Hi, I have a PS3 controller connected, wired, to my LibreELEC device (a raspberry pi 2), as well as a bluetooth adapter, both are working within LibreELEC. Is it possible to configure LibreELEC to use the controller wirelessly?
Activate bluetooth in the LibreELEC settings addon.
Plug the controller in with a cable. Press the PS button on the controller. Then unplug the cable, you should be prompted on screen to pair the device.
