I'm going to go purchase a new whistle. There is a possibility that BT 2.0 does not support the gamepad, despite the fact that it should. Everything functions perfectly via the phone as well as the cable. I will have no choice but to charge the phone with the connection that was attached to the Nintendo Switch Pro Gamepad that I previously used. (It only measures 2 meters in length, but that's adequate for the game. _______________________________________________ . After purchasing a BT 4.0 whistle, I found that the device worked without any issues. _______________________________________________
