'Is there a way of knowing which bluetooth keyboard sent a key event in Android?
Brief description
I have two wireless keyboards connected to the same Android device through Bluetooth LE. Is there any way of knowing which device sent a key event?
Use case
I can call specific Bluetooth methods on each individual keyboard. By pressing any key on each keyboard, I would like to be able to mark it as the currently active device and show it to the user by marking it in green.
What I've tried
I am able to read the KeyEvent through onKeyDown override. Through this, I can use getDevice() and obtain the InputDevice object. But I can't link this to the BluetoothDevice that originated the event. I also tried to use getevent and although it works on the adb shell, I don't have permissions to use this on the app since I must assume the Android device will not be rooted. I have also tried getting the BluetoothHIDDevice through the profile proxy, but I can't get the HID report information.
Is there any way of distinguishing between the two Bluetooth Keyboards on Android?
