I don't know if this is any help, but this is the exception thrown by the app:

I have the same problem with the BLEWatch app crashing. Sending messagas to the TinyDuino with the nRF UART v2.0 app works fine. I have a Nexus 5 with Cyanogenmod 11.

Did someone already manage to fix this?

I looked at the code of the Android App myself, but the only thing I found out is that you have to use

Code: [Select]

BluetoothLeScanner.startScan(List, ScanSettings, ScanCallback) instead of

Code: [Select]

BluetoothAdapter.startLeScan(LeScanCallback)But after that I'm stuck because I'm just not experienced enough to understand how to use those three arguments in the startScan() method...
