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.
