George Edwards / Mbed 2 deprecated BLE_GATT_Example_OCT_15_LIBARY_COMPATIBLE

This fork is functionally identical to the main path, but has been updated to reflect changes in the library APIs, so this code now builds straight "out of the box" without needing modifications

Dependencies:   BLE_API mbed nRF51822

Fork of BLE_GATT_Example by Bluetooth Low Energy
