That is all it does. 6 | 7 | .To use it: 8 | . Install from Play Store 9 | . Pair your Bluetooth devices using Android settings 10 | . Turn Bluetooth ON 11 | . Place an instance of this widget on your home screen (launcher dependent on how you do this) 12 | . Click it to connect a device, again to disconnect. 13 | 14 | The widget will connect if the device is currently not connected, and disconnect if the device is currently connected. 15 | 16 | Become a Beta tester here: https://play.google.com/apps/testing/a2dp.connect2 17 | 18 | This app is a mess.
