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!!!
