iBeacon is a protocol developed by Apple. The main purpose of Beacons (which are simply Bluetooth advertisers - not connectable) is for location-data and proximity marketing.

The MetaWear firmware supports the iBeacon format and can advertise itself as an iBeacon.

To enable iBeacon mode, all you need to do is call mbl_mw_ibeacon_enable and disconnect from the board.

The other functions in the ibeacon.h header file configure the advertisement parameters.
