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

I have a Nexus 5 with CyanogenMod 11.0.

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 Expand

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

Code Select Expand

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...
