How can the iBeacons do this?

• Bluetooth 4.0 low energy

• Two different roles: Central and Peripheral

• In App control, you can connect your app to the bluetooth 4.0 device without the agreement by user

Peripheral

• Role - Has Data

• It can keep broadcasting the advertisement data event no-one connect to it

• When the central connect to it, it can do the continuous data sending(Notify)

Central

• Role - Need Data

• Although you don't connect to the peripheral devices, you can get the advertisement data they broadcasted

• Central controls the connection

Back to iBeacons

• Definitely it is a peripheral

• iBeacons broadcasting the range from your iPhone to them -> if the range is close enough -> iOS tell your app that you're enter the region what you want -> Your app notify the user! That's it!

Thanks!
