I managed run in module BLE nRF51822, thanks to the project nRF5 Arduino Core

https://github.com/sandeepmistry/arduino-nRF5

and the branch nRF5 of the library arduino BLEPeripheral

https://github.com/sandeepmistry/arduino-BLEPeripheral/tree/nRF5

You can get a module nRF51822 in Alixpress for less than $7 dollars

We continue to expect the activation of Bluetooth in the application for testing

Thanks!
