So the title pretty much states it, but to be specific: I'm using a generic bluetooth controller that was designed for switch/android/pc but sold mostly as a switch controller. After a bit of a fight I did get the controller paired via bluetooth, and actually staying connected. It initially was disconnecting after a few seconds, but the connection remains stable now. The problem is that after it's paired and recognized by the computer, the system doesn't read any input from analog sticks and buttons. Connecting via USB all functions work correctly, but nothing via bluetooth.
I don't know if it's a compatibility issue, or a driver issue or something else, but I just need to figure out how to read input.
