title: Bluetooth connection state
body: <p>I've been searching for a while and there doesn't seem to be a way. But..</p>
  
  <p>Is there any intent filter for the connection state of a bluetooth device? I tried using. <code>BluetoothAdapter.ACTION_CONNECTION_STATE_CHANGED</code> but that is never recieved. Yes I do register the intent filter.</p>
  
  <p>In logcat I see BluetoothService Making callback for "UUID" with result 1 right after the device is connected but nothing os received </p>
