Hi and welcome to devnet,

From a quick look at the module, I would first use the QGamepadManager class to check what is available.

I checked the connection with QGamepadManager, its output:

it shows that No.(2848) gamepad has been connected,

If you only have one controller, a more flexible approach would be to take the first value returned by the QGamepadManager rather than hard coding it like that. It's not guaranteed that you will have the same value each time.
