Paul Russell / Mbed 2 deprecated bleIOv04_pr

Experimental BLE project showing how IO can be made with an App over BLE. Pointer to matching App will be added when ready, initially this works with: - Android App [nRF-Master Control Panel], supports Write,Read,Notify - Android Project [BluetoothLeGatt]

Dependencies: BLE_API mbed nRF51822

This is an experimental project for BLE (Bluetooth LE == Bluetooth Low Energy == Bluetooth Smart).

It supports general IO over BLE with Read/Notify/Write support.
It is compatible with FOTA using Android App "nRF Master Control Panel" (20150126)
IO supported by:
- Custom Android App is in the WIKI under: Android-App, developed from Android Sample "BluetoothLeGatt"
- Android App: nRF-MCP (Master Control Panel)
- iOS App LightBlue.
- General HRM, HTM, Battery and similar apps should be able to access the matching services.
It includes combinations of code from other projects, alternative code included can be tried by moving comments (, //)
20150126 bleIO r25: It compiles for both "Nordic nRF51822" and "Nordic nRF51822 FOTA" platforms
20150126 The matching bleIO App (in wiki) doesn't support FOTA yet, use Android App "nRF Master Control Panel"

Feedback and ideas greatly appreciated!!!
