The system shown above reduces burdens involved in host software development by integrating a TCP/IP protocol stack in the WLAN module. User only needs to prepare a host interface driver. For data sent from the host, the BU1805GU automatically add headers according to the TCP/IP, UDP/IP, and WLAN protocols. This allows user to facilitate wireless LAN communication. The system incorporates an UART for host interface focusing in its manageability and versatility even though it has low throughput. The system also incorporates protocols to ensure data transmission and reception, thus enhancing the reliability of data.

2.4. Function Overview The TCP/IP built-in WLAN provides two communication modes according to their intended use (i.e., terminal mode and communication mode) and setting function.

2.4.1. Terminal mode Terminal mode is a communication mode allowing for WLAN communications as if devices were connected with each other via RS-232C interface. As the terminal mode is the same communication method as that for performing communication via the COM port using terminal software (e.g. Hyper Terminal), the said mode is called like this. The terminal mode is initiated by reading the TCP/IP or WLAN setting that was saved in advance at the time of startup. For detail, refer to information in “5. Terminal Mode”.

2.4.2. Communication mode Communication mode is able to achieve a more complex function compared to terminal mode. Since the TCP/IP built-in WLAN employs a packet communication system, it allows communication mode not only to start a system according to preset values of setting parameters like terminal mode, but also make setting changes while in operation. In addition, the communication mode allows for monitoring of device status in real time and use of more advanced functions (e.g. access point detection function). For detail, refer to information in “6. Communication Mode”.

2.4.3. Setting function The setting function allows for setting of UART, WLAN, and TCP/IP. The setting functions are available in two procedures: setting with the use of interactive shell via UART and that with the use of Web browser via HTTP. Setting items can be saved in WLAN device and reflected at the time of a subsequent startup. For detail, refer to information in “4. Config Mode”.

System receives “020” consecutive 8 times

System receives “0F1” or “0x09” consecutive 8 times (ASCII - HEX Frame format)

System receives “0F0” or “0x08” consecutive 8 times (Binary Frame format)

The following table describes the overview of each operation mode.

Mode Description

Initial mode Initial mode is a mode to which the system is set right after the system starts up and used to select an operation mode. While in initial mode, the system waits for an instruction for mode selection from the host for a given period of time (mode selection time). For details of initial mode, refer to information in “3. Initial Mode”.

Config mode Config mode is a mode used to change settings and save setting items.

The system will transit to this mode when “020” is sent in consecutive eight bytes within a period of mode selection time while in initial mode. For details of config mode, refer to information in “4. Config Mode”.

Terminal mode Terminal mode is a communication mode designed to pursue facilitating communications. The system will transit to this mode if no command is sent within a period of mode selection time while in initial mode or run command is entered while in config mode. For details of terminal mode, refer to information in “5. Terminal Mode”.

Communication mode

The communication mode which considered use of the high function. When 0xF0 or 0x08 is sent to a communication mode of ASCII-HEX frame format continuously 8 bytes when 0xF1 or 0x09 is sent continuously 8 bytes in the mode selected time by a mode of initials, I transfer to a communication mode of binary frame format(When shifting to a communication mode, it's notified of by a NULL packet (0x2A and 0x0D)). Data width of UART be 0x09 or 0x08 in case of 7 bits, and please do shifting between terminal modes. Refer to "6. Communication mode" for details of a communication mode.

3. Initial Mode Initial mode is a mode to which the system is set right after the system starts up and used to select an operation mode.

While in this mode, the system sends “’’ (02B)” to the host with a period of 100 ms until the mode selection time is completed (the default is 1 seconds). (It is not sent for a period of one second right

after startup.) The system will transit to config mode when receiving “’ ‘(020)” in consecutive eight

bytes during the said period of time, or will transit to communication mode when receiving “0F1 / 0x09” or “0xF0 / 0x08” in consecutive eight bytes. The system will transit to terminal mode if it receives no command until the mode selection time is completed.

3.1. Automatic Baud Rate Detection While in initial mode, baud rate adjustment can be performed with the automatic baud rate detection function. Note that this function can be used only when data bit is set to 8bit.

The host can trigger baud rate adjustment by continuously sending ‘A’ or ’a’ (“041” or “061”). When

a baud rate is determined, the system will receive “02A” and “00D”.

Sending eight byte of given characters (020 or 0F1/0x09 or 0F0/0x08) after the baud rate is determined allows the system to make a mode selection. Automatic baud rate detection sequence:

5. Terminal Mode Terminal mode is the best suited mode to perform WLAN communications in the same way as that to perform UART communications. Once the configuration has been done, the system can initiate communication without making any setting at the time of startup. Consequently, terminal mode allows for WLAN communications as if devices were connected with each other via RS-232C interface. However, it is not allowed to make any change to TCP/IP and WLAN settings in this mode.

5.1. Features of Communication Protocol Features of the communication protocol used in terminal mode include:

■ Data communications can be done using terminal software ■ Communications performed by the character (No frame needs to be created); ■ Automatic startup/connection (Presetting needs to be done); ■ No online setting changes are allowed ■ Support for power saving ■ Only stand alone mode can be used for WPS The AP More than one STA and Wireless LAN access are made of a mode, but it's only to 1 of STA that you can communicate by a terminal mode.

5.2. Communication Method Terminal mode allows for sending and receiving of data in the range of “000” to “0FF”.

Data are sent in a batch over WLAN after a lapse of set send interval (default 100 ms), or when a

delimiter (default 00D) is sent from the host or data reaches the send buffer size (default 1,460 bytes). Until then, data are accumulated in the internal buffer. Received data from WLAN side are not accumulated in the internal buffer, but sent to the host at the time when the data is received. Note: It is possible to change send intervals with the “uart_intvl” command, delimiter with the

“uart_dlnum” and “uart_dl1/uart_dl2” commands, and send buffer size with the “uart_bufsz” command.

5.3. Support for Power Saving In terminal mode, the power management function compliant with the IEEE802.11 standard can be used as a power saving function. The power management function can be enabled in config mode. When the power management function is enabled, the BU1805GU will be normally in sleep mode. Consequently, the BU1805GU should be awaked to send data. To awaken it, awake characters should be sent as described below. ■ Awake character and limitations

The awake character is four-byte(8bit data only) / five-byte(no data width restriction) “U” (055) character. Although BU1805GU will wake up by other character, DO NOT not use such character other than “U”. There are some implementation which assume “U” as awake character. The following transfer limitations are levied on the awake character:

1) A wait for a period of not less than 300 sec should be provided between first two bytes (or three bytes) and last two bytes. (However, the said wait is not required to transfer data at the baud rate of not faster than 9600 bps.)

2) The four-byte (or five-byte) awake character should be transferred within a limited period of time. This period of time is referred to as a limitation on awake character transfer time and served as a limit value that varies with baud rate.

3) A given wait is required after the BU1805GU is waken up with the awake character until data is

sent (i.e., it is required to wait for the BU1805GU to awake).

■ Baud rates and limit values

Limitation 1 [Wait between awake characters]

Limitation 2 [Limitation on awake character transfer time]

Limitation 3 [Wait between awake character and data]

1200 Not required (4/5 bytes) 45 msec 96 msec




19200 Required (5/6 bytes) 3600 μsec 8 msec







Reference value of the number of awake characters with consideration of Limitation 1 wait. (4byte case/5byte case) Limitation 1 is satisfied by sending specified number of awake characters.

■ No procedures are required to receive data. Just receive data sent from the BU1805GU in the normal way.

■ Awake characters may be sent as WLAN data. (Since the BU1805GU wakes up at a constant period, receiving awake characters at this time will send them as WLAN data.) Consequently, some handling to ignore the awake characters on the receiver side might be required.

■ When the configured power save mode active time (default 10,000 ms) is completed after the BU1805GU wakes up, it will return to the sleep state again. In order to send data from the host after the awake time has elapsed, execute the awake sequence once again. (The power save mode active time can be changed with the “uart_pmact” command.)

■ If only awake character is sent when the power management function is enabled, BU1805GU keep awaking and will not go into sleep state. Therefore make sure to send awake character and data without violating the limitations.

6. Communication Mode Communication mode is suitable to build a more advanced system compared to terminal mode. For terminal mode, settings should be made before the system starts up. In contrast, communication mode allows setting changes to be made online while the system is in operation. Furthermore, utilizing the WLAN functions with the use of configuration packet called WID allows for use of more advanced functions (e.g. the function of detecting access points (site survey function) and that of received signal strength indicator (RSSI)).

6.1. Features of Communication Protocol Features of the communication protocol used in communication mode include:

■ Variable packet length ■ Data form is "ASCII-HEX Frame" or "binary frame". ■ Data transfer identification by socket ■ Online setting changes enabled by using WID ■ Support for power saving As data transfer is performed by frame in communication mode, the data is sent to WLAN when End of Frame (EOF) is detected.

6.2. Communication Frame The following section describes the format of communication frame for communication mode.

There are "ASCII-HEX frame" and "binary frame" in communication frame format of a communication mode. You decide about choice of communication frame format by the data which is at the time of a communication mode shift. ■0xF1/0x09 is received continuously 8 bytes → ASCII-HEX Frame format ■0xF0/0x08 is received continuously 8 bytes → Binary Frame format

6.2.1 ASCII-HEX Frame format Data between SOF and EOF of the communication frame should be converted into ASCII-HEX format. It's mentioned by the binary form so that it may be easy to judge from this specification but an actual length starts to be the next example(HDR=4byte and MSG=0-2936byte).

6.2.2 Binary Frame format

The system the data inserted into SOF and EOF is binary and to which is forwarded. An escape sequence is used to classify cable in the data as SOF/EOF. An escape code is 0x1B (ESC). When 0x2A (SOF) and 0x0D (EOF) exist in whole binary data inserted into SOF and EOF (HDR and MSG), an escape code (0x1B) is added in front of it. Please include an increment of the number of characters by the escape code of MSG in frame size of HDR.(The escape code number of characters of HDR isn't included in frame size of HDR.)

SOF HDR MSG EOF

Before conversion: * 0 8 4 0 5 1 0 A 0 8 0 0 0 2 0 0 0 1 0 B CR

After conversion: 2A 0A 40 51 1B 2A 08 00 02 1B 0D 01 0B 0D

(1) Start of Frame (SOF) SOF is an identifier that indicates the head of a frame (‘’ (02A)) and can be used to detect data misalignment. If data misalignment occurs, the data will be skipped until end of frame (EOF) is received.

(2) Packet type (Parameter “PT” of HDR) Packet type is an identifier that identifies the types of packets. Packets are classified broadly into WLAN communication packets, WID packets, and control packets. WLAN communication packets (DATAIN, DATAOUT) and WID packets (CONFIGRSP, CONFIGREQ) are bidirectional.

(3) Packet length (Parameter “L2-0” of HDR) Used to specify the byte length of MSG region by 12 bits. Since control packets have no MSG region, this parameter is set to “0”.

(4) Message body (MSG) MSG is the body of MSG region. The structure varies with packet types.

The number of characters of the

escape code. (2byte) is included.

Control packets have no MSG region. The contents of WLAN communication packets become the payload of TCP/IP or UDP/IP.

(5) End of frame (EOF) EOF is an identifier that indicates the end of frame (CR (00D)). Data is accepted as frame at the time when this character is received.

besides 0, UDP is effective. [About ICMP Echo Request] ■ Transmission Setting of a socket (10.2.WID in-depth specification referring) isn't necessary like TCP and UDP by a transmission of ICMP Echo Request. The socket ID is set as 0 and the remote address (RADR) is designated. Please give dummy data of a sent length to the message body (MBODY). Data of ICMP Echo Request sent actually (the ID and the sequence number, etc.) is generated by firmware. ■ Reception When firmware receives ICMP Echo Reply to sent ICMP Echo Request, data of socket ID=0 is sent to the host. The sender address is stocked in the remote address (RADR Note-3). ■ Time-out

Retransmission processing is performed as follows by firmware. A host can judge that time-out occurred when the remote address (RADR Note-3) received data of 0. (It'll be sent to a host at most 14 seconds later.) When data of socket ID=0 doesn't return to a host, there is a possibility of (lack of dummy data/data Lost) that ICMP Echo Request from a host isn't normally reaching firmware. ■ Packet example When ICMP Echo Request was sent to "192.168.3.8", and ICMP Echo Reply was received.

Sockets The following combinations are referred to as a socket, respectively. • UDP socket: Local IP Address and Local Port Number • TCP socket: Local/Remote IP Address and Local/Remote Port Number While in communication mode, settings, reference, and data transfer are executed to sockets. A maximum of eight sockets (four each for TCP and UDP) can be used. Accesses to the sockets are identified by relevant socket ID.

6.7. Support for Power Saving Two types of power saving functions are available for use in communication mode.

■ IEEE802.11-compatible power management function (set by WID_POWER_MANAGEMENT)

■ Sleep function of the ROHM’s proprietary specification (set by WID_POWER_SAVE) These power saving functions can be used only by STA mode. The power management of IEEE802.11 standard is practicable only by BSS-STA mode. In order to execute the IEEE802.11-compatible power management function, set “WID_POWER_MANAGEMENT” to “Enabled”. While the power management function is set to “Enabled”, the BU1805GU repeats awake and sleep modes at its own timing. To send a frame from the host, the BU1805GU should be set to the awake state in advance. In order to execute the sleep function of the ROHM’s proprietary specification, set “WID_POWER_SAVE” to “Sleep”. While in sleep mode, all functions except for the function of detecting UART reception are disabled. Setting “WID_POWER_SAVE” to “Active” will return the BU1805GU to the state before sleep mode. In both power saving modes, BU1805GU should be set to the awake state in advance to send data.

■ Awake character and limitations

The awake character is four-byte(8bit data only) / five-byte(no data width restriction) “U” (055) character. Althgouh BU1805GU will wake up by other character, DO NOT use such character other than “U”. There are some implementation which assume “U” as awake character. The following transfer limitations are levied on the awake character:

1) A wait for a period of not less than 300 sec should be provided between first two bytes (or three bytes) and last two bytes. (However, the said wait is not required to transfer data at the baud rate of not faster than 9600 bps.)

2) The four-byte (or five-byte) awake character should be transferred within a limited period of time. This period of time is referred to as a limitation on awake character transfer time and served as a limit value that varies with baud rate.

3) A given wait is required after the BU1805GU is waken up with the awake character until data is

sent (i.e., it is required to wait for the awake of the BU1805GU). ■ Baud rates and limit values

Baud Rate (bps)

Limitation 1 [Wait between awake characters]

Limitation 2 [Limitation on awake character transfer time]

Limitation 3 [Wait between awake character and data]

1200 Not required (4/5 bytes) 45msec 96msec




19200 Required (5/6 bytes) 3600μsec 8msec





460800 Required (22 /23bytes) 1000μsec 4msec


Reference value of the number of awake characters with consideration of Limitation 1 wait. (4byte case / 5byte case) Limitation 1 is satisfied by sending the specified number of awake characters.

■ No procedures are required to receive data. Just receive data sent from the BU1805GU in the normal way.

■ Awake characters may be sent as WLAN data. (Since the BU1805GU wakes up at a constant period, receiving awake characters at this time will send them as WLAN data.) It

might be required to implement some handling procedure to ignore the awake characters on the receiver side.

■ When the configured power save mode active time (default 10,000 ms) is completed after the BU1805GU wakes up, it will return to the sleep state again. In order to send data from the host after the awake time has elapsed, execute the awake sequence once again. (The power save mode active time can be changed with the “uart_pmact” command.)

■ If only awake character is sent when the power management function is enabled, BU1805GU keep awaking and will not go into sleep state. Therefore make sure to send awake character and data without violating the limitations.

Note: Limitation 3 [Wait between awake character and data]

Communication mode allows for making a query about awake using null packet (02A, 00D). Sending a null packet instead of Limitation 3 (wait between awake character and data) and then waiting for another null packet makes it possible to confirm that the BU1805GU wakes up.

9. TCP/IP Protocol Stack This Chapter describes specification for TCP/IP protocol stack.

9.1. Features ■ Support IPv4, ARP, ICMP, UDP, and TCP protocols ■ Support DHCP client and DNS client functions ■ TCP/IP configuration allowed in config mode or using WID in communication mode

9.2. Host Communication Data User can perform communications just by exchanging the payload of TCP/IP and UDP/IP according to the frame format specified in “14. UART Communication Specification”, without regard to TCP/IP, UDP/IP, and WLAN.

Payload FCS

Portion user sends and receives

Ethernet header

IP header

TCP, UDP header

WLAN header

ARP and ICMP are automatically processed by internal TCP/IP protocol stack of the BU1805GU. As described in “6.3 Data Packet Structure”, the information of the remote terminal can be derived from the received data in communication mode. In addition, the destinations of UDP/IP can be changed for each data.

9.3. Setting Parameters The table shown below lists user-configurable parameters related to TCP/IP protocol stack.

Setting Parameter Setting Item Default

Use of DHCP DHCP function enabled or disabled Disabled

IP Address Local IP address 192.168.0.1

Subnet Mask Subnet mask 255.255.255.0

Gateway IP address of default gateway 192.168.0.254

DNS Address IP address of DNS 192.168.0.100

Protocol Protocol (UDP, TCPs, or TCPc) TCP server (*)

Local Port Number Local port number 16384 (*)

Remote Port Number Port number of remote terminal 16384 (*)

9.4. Specification of Each Block This Section describes the specification of each block contained in the TCP/IP protocol stack.

9.4.1. IP block (Internet Protocol) The BU1805GU receives and processes a packet only when the destination IP address of the packet corresponds to own IP address, or it is broadcast IP address.

(1) TOS (Type of Service) TOS is a value indicating the service quality of IP being sent. With the BU1805GU, TOS is set to “0”.

(2) TTL (Time to Live) TTL is a value indicating how many routers data is allowed to pass through. With the BU1805GU, TTL is set to “64”. If the number of router passed exceeds this value, the packet will be discarded.

(3) Broadcast and Multicast It is always ready to send and receive broadcast frame. UDP protocol must be used to send and receive broadcast frame. BU1805GU supports directed broadcast addresses such as “192.168.11.255” and limited broadcast address such as “255.255.255.255”. The reception of a multicast and the setting are possible by only a communication mode.

(4) Fragmentation No fragmentation is performed on frames.

9.4.2. ICMP (Internet Control Message Protocol) Echo Reply and Time Exceeded message of ICMP is supported. Due to a limitation on internal buffer size, echo reply will not be returned if echo request size exceeds 1,460 bytes (That ICMP Hedda is included, 1468 bytes).

9.4.3. ARP block (Address Resolution Protocol) APP cache size is “8”. APP entry information that has not been used for a period of 20 minutes is automatically deleted.

9.4.4. UDP block (User Datagram Protocol) UDP sends and receives data without being connected to the remote host. The number of ports that can be used at a time is a maximum of 4 (1 in terminal mode). Broadcast frame can be sent and received only with UDP.

62/172

9.4.5. TCP block (Transmission Control Protocol) Unlike UDP, TCP is the connection type and thereby sends and receives data after securing a communication channel with remote terminal. TCP supports only unicast frame communication. The number of ports that can be used at a time is a maximum of 4 (1 in terminal mode).

(1) Number of Session The number of sessions that can be used at a time is 4 (1 in terminal mode).

(2) Time-out Value The table below shows time-out value settings.

Parameter Set time

Connection time-out 75 sec.

Disconnection time-out 75 sec.

Send time-out 64 sec.

Resend time-out Default: 3 sec., Setting range: 500 ms to 60 sec.

Delay ACK time-out 200 ms

(3) TCP Congestion Control This control supports high-speed resend and high-speed restore. The number of duplicate ACK is 4.

9.4.6. HTTPs block (Hyper Text Transfer Protocol Server) The HTTPs block is provided to make settings of TCP/IP Built-in WLAN using Web browser, and not available for communications.

9.4.7. DHCPc block (Dynamic Host Configuration Protocol Client) DHCP client acquires IP address that can be used over a network from the DHCP server. The IP address acquired can be retrieved.

9.4.8. DNSc block (Domain Name System Client) The DNSc block allows for specifying a destination by name of 255 or less characters (34 or less

characters in terminal mode) in place of IP address. IP address is acquired by DNS client by making an inquiry to the DNS server.

See WID_IP_RESOLVE.

9.4.9. DHCPc block (Dynamic Host Configuration Protcol Sever) A DHCP server distributes an IP address to a DHCP client. It's possible to establish distributed IP address and lease time.

9.4.10. IGMP block (Internet Group Management Protcol) IGMPv2 is being supported. (IGMPv1 plug-compatible is also supported.) Participation in a multicast group (Join), Leaving from a multicast group (Leave), Maintenance of a multicast group (Report reply to Query), There is a function which says so. A Report response time to Query is 10 seconds.

10.2.13. WID_WEP_KEY_VALUE 0x3004 String R/W

Description: Used to set WEP key and refer to the setting. Before setting WEP key, be sure to make setting of the “WID_802_11I_MODE” command. This WID command supports only WEP key index “0”. (Be sure to set the WEP key on the AP side to index “0”.)

Set value: Null-terminated hex string of 10 or 26 characters

Default "0000000000" Make WEP key setting with a hex string of 10 characters for WEP64 and a hex string of 26 characters for WEP128. WEP key setting with insufficient number of characters impairs operation guarantee. Example:

To use the registration key of “AIR01” with WEP64, the registration key setting comes to "4149523031", and further converts the characters to ASCII code 0x34 0x31 0x34 0x39 0x35 0x32 0x33 0x30 0x33 0x31. Then, take these values as set values.

'A' → 0x41 → 0x34, 0x31 'I' → 0x49 → 0x34, 0x39 'R' → 0x52 → 0x35, 0x32 '0' → 0x30 → 0x33, 0x30 '1' → 0x31 → 0x33, 0x31

10.2.20. WID_POWER_MANAGEMENT 0x000B 8bit R/W

Description: Used to make setting of IEEE802.11-compatible power management function and refer to the setting. Setting the power management function to “Enabled” will allow for data communication while achieving reduction of power consumption and maintaining connection to AP. (However, this results in communication performance degradation.) The following section describes precautions to be taken during the power management function is being executed:

Processing while in AP scan mode is changed to intermittent processing. While in any mode other than scan mode, the system is put into a sleep mode.

Setting this WID to Power management (Max) will ignore the DTIM interval of AP. Consequently, communications may present problems depending on applications to use.

Set values:

Set Value Function Remark 0x00 Power management disabled

0x01 High-speed power management (Normal)

0x02 High-speed power management (Max)

0x03 PS-POLL power management (Normal)

0x04 PS-POLL power management (Max)

The high-speed power management is a process that, when AP provides notification that it wants to send data, temporarily exits from power save mode (sends a awake NULL frame) and receives data sent from AP all at one time, and subsequently returns to power save mode (sends a sleep NULL frame). In contrast, the PS-POLL power management is a standard process that, when AP provides notification that it wants to send data, sends a data request frame called PS-POLL while maintaining the power save mode to receive MSDUs one after another. Consequently, if two or more MSDUs are accumulated at AP, the high-speed power management function provides higher responsiveness.

Packet example: Example where it turned out that this WID had been set to “Disabled”, when referring to the power management function setting:

TX: 0640510106000B00

RX: 0830520108000B000100

10.2.21. WID_POWER_SAVE 0x010D 8bit W

Description: Used to make setting of power save function of the ROHM’s proprietary specification and refer to the setting. This function can be used to stop WLAN for an extended period of time. If this WID command is set to “Sleep”, the system will be put into a sleep mode as soon as it receives the WID command. Since it is the same even if AP is connected, data frames that have been sent later may be discarded. Returning from the quiescent mode impairs guarantee for line connection to AP. If AP already disconnects the line, the device tries to reconnect the line. To return from sleep mode, set this WID to “Active”. CAUTION: Do not set this WID to “Sleep” while in sleep mode. Be sure to set the WID to “Active” once, and then issue a sleep instruction again. While in sleep mode, the time management function in the module stops and the time maintained by the timer is not guaranteed.

Set value:


0x00 Active

0x02 Sleep

10.2.22. WID_LISTEN_INTERVAL 0x000F 8bit R/W

Description: Used to set listen intervals and refer to the setting. This WID is designed to make adjustment of awake timing of the BU1805GU in power management mode. The larger the set value, a period of time to continue sleep mode becomes increasingly longer. This contributes to power saving, but correspondingly results in longer time to respond to communication. Furthermore, setting this WID to an excessively-large value may cause the AP side to refuse connection. (Whether or not the AP side refuses connection depends on the AP specification.)

Set value: 1 to 255

Default 3 The set value means the number of beacons. Beacon interval setting is done by the “WID_BEACON_INTERVAL” command.

10.2.23. WID_WPS_DEV_MODE 0x0044 8bit R/W

Description: Used to set WPS device mode. Device mode is designed to specify whether to maintain a credential within the device (stand-alone mode) or by the host (host control mode). While in stand-alone mode, a credential is recorded in EEPROM within the device and the device tries to make connection according to the stored credential for the subsequent startup. Note that only one credential can be recorded. Host control mode is designed not to record any credential in EEPROM. The host will save and set credentials instead. This mode allows two or more credentials to be managed by performing WPS protocols with two or more APs. Setting this WID to “Stand-alone mode” will automatically initiate connecting to the relevant AP after completion of WPS protocol. In contrast, setting the WID to “Host managed mode” will not initiate connecting to the AP even after completion of WPS protocol until the host makes credential setting.

Set value:

10.2.31. WID_SITE_SURVEY 0x000E 8bit R/W

Description: Used to set mode of site survey (AP/STA scan) function and refer to the setting. Site survey is the function of consciously searching for AP and STA and acquiring a list of them. The following section describes the procedure for connecting to intended AP and STA. 1. Select a mode with the “WID_SITE_SURVEY” command. 2. Make filter setting with the “WID_SCAN_FILTER” command. 3. Start a site survey with the “WID_START_SCAN_REQ” command. 4. Acquire the results of the site survey with the “WID_SITE_SURVEY_RESULTS” command. 5. Request connection to the intended destination with the “WID_JOIN_REQ” command. Making a connection request with the “WID_JOIN_REQ” command will automatically return the

set value of the “WID_SITE_SURVEY” command to “Site survey disabled” (002). When connection is made with the “WID_JOIN_REQ” command, the connection operation will be continued until it is detected even if the specified AP cannot be detected for some reason (Forced connection mode). To clear forced connection mode, use the “WID_SSID” command to make SSID setting again.

Set value:


0x00 Single channel scan mode

0x01 All channels scan mode

0x02 Site survey disabled

Single channel mode is used to execute AP and STA scan on the channel set with the “WID_CURRENT_CHANNEL”. (There are cases where AP and STA of adjacent channels are included.) All channels scan mode is used to execute AP and STA scan on all channels. When site survey disabled is selected, site survey is not performed and the device will try to connect to the AP of specified SSID. Unless this WID is set to “Site survey disabled”, the function of automatic connection to the specified SSID will not become enabled. (In order to autonomously maintain the connection wait status while in ad hoc mode, set this WID to “Site survey disabled”.)

Packet example: Example where it turned out that this WID had been set to “Single channel scan mode”, when referring to the site survey setting:

TX: 0640510106000E00

Description: The session cutoff time-out which is at the time of TCP/IP transmission. When this set time (second) is exceeded after TCP data transmission, a session is cut. A buffer inside the firmware is limited, so when doing transmission processing in more than one session, for example the buffer which is used for only 1 session in it at the other sessions when retransmission processing of TCP is repeated, becomes little.Advance cutoff of TCP/IP by making this set value short and do communication of a normal session smoothly by such case. But, when this setting is established short, the cutoff measure which is at the time of TCP/IP transmission is advanced, so please be careful.

Set value: 1 to 255 (Unit : Second) Default = 64 second It's necessary to establish this setting before building of TCP/IP session. This timer is exercised in the time when a transmission timer of TCP/IP has expired. In other words, the session cutoff time-out when sending, will be this setting + the expiration time of a transmission timer. (Choose a transmission timer in the communication state by the price of at most 60 seconds and fluctuate)

Line feed code ReceiveCR(0x0D), SendCR(0x0D)

Firmware is downloaded and activated by sending a command to the boot loader of the BU1805GU.

12.1.1 Commands The table shown below describes commands used to download firmware.

Command Function

fld Used to set the system to firmware download mode. For this purpose, baud rate must be set to “115200”.

fgo Used to start firmware execution.

12.1.2 Procedure ■ After starting terminal software, power up BU1805GU in UART host load mode. Then a

prompt “ROM>” is sent from BU1805GU and displayed on the console. ■ When the "fld" command is sent after the prompt is received, the boot loader will be put into

download mode. ■ After sending the "fld" command, send the binary file of firmware as continuous data. ■ By sending “fgo” command after the "ROM>" prompt is received, the downloaded firmware

execution will start. Downloading flow is as described below. (Characters sent from the host are italicized.)

13. Firmware Writing This section assumes the external flash memory is used in the system, and describes about flash writing procedure and how to start executing firmware. Flash writing must be done in UART host load mode and the firmware execution with the program store in the flash memory must be done in Flash ROM load mode. The UART setting and the commands used in the procedure are same as that described in “12 Firmware Execution”

13.1 Firmware Writing Procedure ■ After starting terminal software, power up BU1805GU in UART host load mode. Then a

prompt “ROM>” is sent from BU1805GU and displayed on the console. ■ After the prompt is received, download firmware and the flash writing program as binary data

using “fld” command. ■ (flash writing program is different for flash area 0 and 1). ■ After receiving "ROM>" prompt, entering “fgo” command will start flash writing program

execution and the firmware is written into flash memory. These operation flow is shown below.(Characters sent from the host are italicized)

13.2 Flash ROM Boot In order to start operation with the firmware stored in the external flash memory, power on BU1805GU in Flash ROM load mode. Then the firmware is automatically downloaded from the external flash memory after the reset is released and the firmware execution start. FLASH_SEL pin is used to select the flash area 0 or 1 where the firmware is loaded from. Refer to “3 Initial Mode” for operating mode selection after firmware execution start. The following example shows the flow of entering config mode and confirm firmware version by ver command.

13.3 Initialize Setting When the firmware is updated, default setting needs to be restored. The procedure is shown below.

13.4 Change in firmware It's returned in the state before a firmware start by a PRST (power-on reset) signal and firmware is started once again based on setting of reset latch (11.2. Setting referring of reset latch) to change moving firmware. (STA calls the AP mode STA and the AP firmware at this chapter.)

13.1 About the set value of EEPROM The setting is reflected by the preserved set value at the time of a firmware start in EEPROM.A host can change it to the optional price after a firmware start by a communication mode, so while it "is until a host establishes it from a firmware start that the set value in EEPROM influences", it'll be. The set value in EEPROM is interchangeable by STA and the AP firmware. It's possible to share and use, but please confirm the following about the function to which each firmware is peculiar. [Function to which STA firmware is peculiar] * The communication type :IBSS-STA (ad hoc) and BSS - STA (infrastructure) After preserving this setting by STA firmware, when the AP firmware is started, the communication type

will be "The AP (wlan of an access point/a terminal mode_type It's transcribed with infrastructure by the command.)".

[Function to which AP firmware is peculiar] * The communication type :AP(Accsess point) After preserving this setting by the AP firmware, when STA firmware is started, the communication type

will be "BSS-STA (infrastructure)". * DHCP fanction :DHCP server After preserving this setting by the AP firmware, when STA firmware is started, the DHCP function will

be "invalidity".

13.1 About default value setting One copy is different in the default value of STA and the AP firmware. When returning it to the default value, please be careful.

Setting Default of STA firmware Default of AP firmware Gateway address 192.168.0.254 192.168.0.1 DNS address 192.168.0.254 192.168.0.1 DHCP fanction Disenable Server

14. UART Communication Specification This Chapter describes the specification for UART communication between the host and the BU1805GU.

14.1. Setting The table shown below describes UART setting specification.

Parameter Setting

Baud rate 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600

Data width 7, 8 (bits)

Parity None, Odd, Even

Stop bit 1, 2 (bits)

Flow control None, RTS/CTS

Inter-character delay time 0, 100, 200, 300 (us)

14.2. UART Flow Control BU1805GU is designed to support hardware flow control with RTS/CTS. Signal specification is compliant with the RTS/CTS flow control of UART. RTS is used to request not to send data. If data is too much to be received, the BU1805GU will set RTS to “High”. If data becomes able to be received, it will set RTS to “Low”. CTS is used to confirm the receive ready status of the counterpart. Data cannot be sent while CTS is set to “High”, and be sent when it is set to “Low”. (Using the flow control allows for enhancing the reliability of communication data, but this does not guarantee of the prevention of data loss at the UART level.)

15. WPS Connection Examples The function with which security information on WLAN is registered is called Registrar. The function which receives a delivery of WLAN security information is called Enrollee. It's possible to use the Enrollee function by BSS-STA mode. It's possible to use the Registrar function by the AP mode. A setting example of a WPS connection of the Enrollee function and the Registrar function is indicated.

15.1. Connection example of Enrollee

15.2. Shell Setting The following section describes the procedure for making a WPS connection using the Shell command. Only WPS stand-alone mode (that automatically saves credentials in EEPROM) can be used with shell setting. ■PBC method … Push PBC button of AP and then enter the following command.

wlan_wps set pbc Start a WPS connection using PBC method.

■PIN method … Set the PIN code to AP and then enter the following command.

wlan_pin set xxxxxxxx Enter PIN code.

wlan_wps set pin Start WPS connection using PIN method.

■Confirm a WPS connection.

wlan_wps get If “stop” is displayed, this means that WPS has been completed.

wlan_con If “Connected” is displayed, this means that the connection has been completed. (CAUTION: While in ad hoc mode, “Connected” is displayed at all times. However, by starting a WPS connection, “Disconnected” is displayed.)

■To enable WPS connection using credentials when turning ON the power supply, enter the following

command.

wlan_crdl set on Enable a WPS connection at startup.

15.3. Web setting The following section describes the procedure for making a WPS connection using the Web setting. Same as the Shell setting, only WPS stand-alone mode (that automatically saves credentials in EEPROM) can be used with Web setting. In the following description, the parameters shown in the table below (same as default) are assumed to be used for connection. The IP address of access point is assumed to be “192.168.0.254”.

■Connection procedure (Example of PBC method) (1) Disconnect the wired LAN cable from a personal computer. (2) Enable the WLAN of the personal computer and the set IP address to “192.168.0.2”. (3) Make the WLAN setting of the personal computer to the parameters listed in the table

above. (4) Access to “192.168.0.1” using the Web browser. (5) Press the WPS push button of AP. (6) Set the “WPS Connection” parameter in the “WPS Window” in the Web browser to “PBC”,

and then press the “Apply” button. (7) Disable the WLAN of the personal computer. (8) Connect the personal computer to AP using the wired LAN cable, and then set the IP

address of the wired network to “192.168.0.2”. (9) Access to “192.168.0.1” using the Web browser. (If the access is possible and the setting

menu is displayed, this means that the WPS connection has been successfully completed.) (10) In order to enable a WPS connection using credentials for the next startup, Set the

“Credential connection on startup” parameter in the “Wireless Config Window” to “Enable”, and then press the “Apply” button. Subsequently, set the “Save" parameter in the “System Window” to “On”, and then press the “Apply” button. WLAN will be connected to AP according to the credential information even after turning OFF and ON the power supply.

(11) If Step (10) is not conducted, WLAN connection will be done based on WLAN setting without using credential after OFF and ON the power supply. Since the credential information is saved, setting the “Credential connection on startup” parameter in the “Wireless Config Window” to “Enable” and “Save” it will allow WLAN to be connected to AP after turning OFF and ON the power supply.

15.4. WID Setting The following section describes the procedure for making a WPS connection using the WID command. The WPS stand-alone mode (that automatically saves credentials in EEPROM) and the host managed mode (credentials are retained by the host) are available for selection. ■Connection procedure (Example of PIN connection using the stand-alone mode)

(1) Set the “BSS type” parameter to “Infrastructure” (WID_BSS_TYPE0).

(2) Set to WPS stand-alone mode (WID_WPS_DEV_MODE0). (3) Set PIN code (WID_WPS_PIN). (4) Put AP into a WPS ready state (Enter the PIN code to AP).

(5) Start WPS connection (WID_WPS_START1). (6) Set the “Credential connection for startup” parameter to “Enabled” when turning ON the

power supply (WID_MAINTE_CRDL1). ■Connection procedure (Example of PBC connection using the host managed mode)

(1) Set the “BSS type” parameter to “Infrastructure” (WID_BSS_TYPE0).

(2) Set to WPS host managed mode (WID_WPS_DEV_MODE1). (3) Put AP into a WPS ready state (Press the push button).

(4) Start WPS connection (WID_WPS_START2).

(5) After completion of the WPS connection (WID_WPS_START0), acquire credential (WID_WPS_CRED_LIST).

(6) Make setting of the acquired credential (WID_WPS_CRED_LIST). Note: For the next startup, conduct Steps (1), (2), and (6).
