AltBeacon program for embedded BLE. This program demonstrates how to set up a BLE device to broadcast AltBLE compatible data. Please see the official website for more details. https://github.com/AltBeacon/spec and http://altbeacon.org/
Dependencies: BLE_API mbed nRF51822
Fork of BLE_AltBeacon by
Description
AltBeacon is an open beacon standard developed by Roving Networks. AltBeacons an alternative to the closed sourced and heavily licensed iBeacon standard.
