Bluetooth Low Energy Serial Communication

[Donald Gordon]

I am using a Sparkfun Pro nRF52840. I wish to  communicate with it serially. I found the UUIDS it exposed : UART Service = 6E400001-B5A3-F393-E0A9-E50E24DCCA9E TX Characteristic = 6E400002-B5A3-F393-E0A9-E50E24DCCA9E RX Characteristic = 6E400003-B5A3-F393-E0A9-E50E24DCCA9E. These I believe are Nordic UART ids. I've written a Bluetooth classic android app using BroadcastReceivers and the SPP uuid. I'm not sure how to communicate serially via BLE. Any Help/tutorial recommendation would be appreciated.

Won't work - it must be BLE.

At the Android end?
