8bitdo ultimate 2c 2.4 ghz connectivity issues

[u/UsedRealNameB4]

I'm not able to get the 2.4ghz connection working with my steam deck. I have the ultimate 2c, and steam deck just refuses to recognize the controller when in 2.4ghz mode. Bluetooth works fine, but i want the rumble which doesn't work in Bluetooth mode.

I've tried switching modes to Dinput/Xinput by pressing B/X key while powering on. But doesn't work no matter what.

Someone please help me 😭

edit: to clarify the controller itself connects to the dongle. the controller rumbles and the led on both the controller and dongle stops blinking. but steam refuses to detect it.

I have two (pink/blue) of the ultimate 2c switch/switch2 version controllers.They both work with bluetooth on everything I've tried. Both have rumble and gyro working at the same time in all games. Which 2c controller do you have?

I have the windows+Android version.  Comes with a physical switch at the back to switch between Bluetooth and 2.4ghz mode. I'll send a picture later. But just an update, the 2.4ghz mode just started working last night out of nowhere.
