Description
Is there an existing issue for this?
- This is a bug in RetroArch frontend
- I have searched the existing issues
Description
System: Debian 11 amd 64, linux kernel 6.1, libsdl2 v2.30.11
Bluetooth: tp-link cpi express Wifi6 + bluetooth v5.2
RA version: 1.20.0 last commit.
Compilation: GCC 10
Problem: Rumble not works way bluetooth.
Expected behavior
The problem I have is with the Xbox one S gamepad and Amazon Luna. They work fine via cable, both rumble and controls, especially in udev.
The problem is with bluetooth, if I charge the controllers via udev it is impossible for me to calibrate the sticks, the recognition is totally unbalanced to the point of not recognizing some directions, but the rumble works fine, at least on the xbox controller.
On the luna controller neither the sticks nor the rumble work well, and some buttons overlap, something that does not happen with cable.
However, if I choose the controller driver via SDL2 (in whose code there is support for the luna controller vibration) the xbox controller seems to work correctly via bluetooth, at least there are no problems with the buttons, but some rumble motor seems to fail.
The Luna controller in the only mode that works well via bluetooth is way SDL2, with the other controls it has duplicate buttons, but there is no way for the rumble to work. I understand that the sdl2 joypad code would have to be updated.
Steps to reproduce the bug
-
Connect gamepads way wire and test in pcsx rearmed with padtester 1.1 elf, all works fine.
-
Same that stip 1 but way bluetooth, problems in the button, in SDL2 drivers buttons works, but not rumble in luna gamepad.

Research direction
Start with the SDL2 joypad code, since the issue identifies it as the path where the Luna controller works over Bluetooth but lacks rumble. Reproduce the behavior on Debian 11 with the Xbox One S and Amazon Luna controllers using the listed wired and Bluetooth steps, then verify button mapping, stick calibration, and rumble for both controllers.
