LED brightness control

[XJIOP]

Is it possible to add LED brightness control? I know this can be done when Xbox Controller is connected by wire or Xbox Wireless Adapter except Bluetooth.

What I found:

• LED can be controlled with cmd SETX SDL_JOYSTICK_HIDAPI_XBOX_ONE_HOME_LED 0.05 then start Steam.
• Paid app reWASD can do it.

I thought about this before (months ago) and explored it further then, not long after this commit:
Added the hint SDL_HINT_JOYSTICK_HIDAPI_XBOX_ONE_HOME_LED to control the brightness of the Xbox button LED on the Xbox One controller (libsdl-org/SDL@24cdebe)

I tried it and it did not work so I contacted the creator of SDL (@slouken) to find out why and got the answer that it requires a driver on Windows to work. That is how Steam and reWASD work.

There could be a simple program (just like this one) that comes with a driver and controls only the Xbox Controller's Xbox button light/LED that is also open source and free (just like this one). I am currently not aware of such program. It may or may not exist (yet) and may need to be created.

There is a free solution with Steam, it looks like the best free method at this time:

Perhaps this can be done through xinput.dll?

No, currently a driver is required on Windows.

It should be possible to change the Xbox Controller's Xbox button light/LED brightness using the official Xbox Accessories app. Hopefully it will be added soon.
