Bluetooth Low Energy / Mbed 2 deprecated BLE_AltBeacon

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 Austin Blackstone

Description

AltBeacon is an open beacon standard developed by Roving Networks. AltBeacons an alternative to the closed sourced and heavily licensed iBeacon standard.

For full details please see the AltBeacon repository
