Bluetooth controller brand & name

8bitdo Ultimate 2C

What is problem? (only list ONE problem per report)

The Ultimate 2C controller connects but behaves erratically, rapidly firing commands I haven't pressed. I have had the same thing happen with two different 2C controllers. The 8Bitdo Arcade stick however behaves completely normally.

What did you expect to happen?

I expected the controller to not send button presses by itself.

Attach files like logs or Bluetooth traces here

No response

Same thing here. I understand the controller does not support x-input over bluetooth so the analog triggers aren't going to work anyway, but I'm a little confused why blueretro seems to be receiving all kinds of phantom inputs when nothing is pressed.

I'm using the LaserBear BlueRetro GC V3 and the Ultimate 2C Wireless controller in bluetooth mode.

Is it better in v25.01?

[brettinman]

Unfortunately no, same behavior of seemingly random rapid-fire button presses.

Attaching a debug file where I start the console and connect the controller in question (I had to change the extension to .txt for Github to allow the upload, please change the extension back to .bin).

@brettinman your trace is invalid, did you follow the instruction and enable debug mode?
