Whenever I connect a Bluetooth controller it doesn't work but when I plug the same controller through USB into the computer it works.

Please specify the OS you're using.

Windows 10

Uh that's very weird.

Please try to look if SDL Gamepad Tool can detect input from your Bluetooth Controller.

Also make sure that the controller name is not orange in LambdaControls' GUI.

SDL Gamepad Tool doesn't detect input and the controller name is not orange.

If SDL Gamepad Tool doesn't detect input then there's not much I can do as it's likely an issue with a driver or something else.

Does the controller with bluetooth work with any other application?

@supsm Yes. Steam detects the controller.

Does the controller work or is it just being detected?

The controller works and I'm able to move and play other games using it.

And btw it's a PS4 Controller. If that's useful info at all.

that's very weird

@LambdAurora in this case it's probably an issue with lambdacontrols as it works with other games which means it's likely not a driver issue
