I just paired my bluetooth gamepad using https://www.cnet.com/how-to/how-to-setup-bluetooth-on-a-raspberry-pi-3/
Since it's a gamepad (it has a keyboard button but I'm usng in gamepad ode), it should appear at /dev/input or /dev/jsX, right? There's only mice in /dev/input and /dev/jsX doesn't exist.
Maybe I should bring a kernel module myself?
I'm using raspbian server.
