Austin Blackstone / Mbed 2 deprecated ble-scanner-demo-beacon

BLE beacon code designed to be remotely compiled by the ble-scanner-station-demo code. https://github.com/BlackstoneEngineering/ble-scanner-station-demo

Dependencies:   BLE_API mbed nRF51822

Fork of BLE_GAP_Example by Bluetooth Low Energy

This code is meant to be used as a target for remote compilation. Users can pass in the NAME variable to change the broadcast name of the beacon being compiled.

This program is meant to be used in conjunction with the NodeJS ble-scanner-station-demo webapp and the remote compile api JS webapp.

The NodeJS ble-scanner-station-demo will display a webpage like the following. The Orange text will be replaced with the name of the beacon. For more details see the repo page
