Xbox Series X controller Joysticks too sensitive in wireless with PICO 2 W

[LeGittee]

The Xbox Series X controller is too sensitive when used wirelessly with the PICO 2 W board. I tested this on an Xbox 360 with the 1.0.0.9 build. This problem does not happen when the same controller is used wired on the RP2350 USB-A or the Pico, it makes game play more difficult in action games.

The controller was an Xbox Series X controller, I assume the Xbox One controller behave similarly

Tested on: Xbox 360

Board used: PICO 2 W

Have you tried changing your sensitivity in the Web App?

No, I hadn't tried the webapp, I did not know I could. After a few minutes figuring out how to use it, I could try it. The bluetooth feature makes it easy to go back and forth to tweak the values however the adapter seems to stay "stuck" sometimes after saving the settings. Unplugging-plugging seems to get around the issue. Also, some values seems not to display at the value they were previously set when coming back to the webapp, which is a little confusing.
Tweaking the deadzone (value between 5 and 10 %) and the "curve" (value of 0.30) values reduced the sensitivity and improved playability.
However the sensitivity curve is still different from the one of an Xbox 360 controller. My impression is that they have a steeper curve towards the end of the range, the steeper part beginning maybe in the last 3rd or quarter of the range. Maybe a curve similar to the positive side of the -400/(x-104) function for example.
But I don't know what the "curve" feature of the webapp does, maybe it is already doing this ?
Also I wanted to ask what the uncap feature does, could it help with this issue ?

I do apologize I haven't looked much into the web app as I know it does certain things but I don't know everything on it atm. I've mostly just updated the firmware side. I can absolutely take a look and see what those values do.

For the time being it may be best that you adjust the values to your preference in the web app as if I change it for everyone then everyone may not agree with the default sensitivity and keep requesting it to be changed.

I will gladly look into the rest of your questions and see what the issue is that's causing the freezing when I have a moment!
