BLE FOTA / Mbed 2 deprecated mbed_fota Featured

Bluetooth Low Energy based Firmware Over The Air with Mbed. Mbed part is a external processor of the IoT devices and communicate with a Bluetooth module. The Bluetooth module have to support BLE and implement BLE FOTA profile designed by ours. BLE FOTA profile specification is available from our GIT hub wiki(https://github.com/sevencore/BLEFOTA).
