PRESSING Fn+F1 Fn+F2 HERE: NO EVENTS FIRED. Input device name: 'Bluetooth 3.0 Macro Keyboard' Input device ID: bus 0x5 vendor 0x5ac product 0x22c version 0x11b The manual describes absolutely none of the special functions that the Fn keys map to, so I've guessed them in the comments below. This is the output from evtest when pressing various function keys with and without the Fn modifer key.Īccording to manual that came with the keyboard my revision is: Ver:08+BT/A/2.8 I haven't tested with other Linux distros.) (The keyboard works fine in Windows, fwiw. Maybe someone out there with more Linux knowledge than me (not a high bar to reach) knows how/if this can be remedied. My feeling is it's a Raspbian driver issue, not specific to RetroPie.

I notice that the device name in the Bluetooth Setup menu is simply 'Bluetooth 3.0 Macro Keyboard', which sounds pretty generic to me. the scancodes are not being translated properly by the keyboard driver. I'm guessing (and it really is a guess) that this is a problem at the driver level i.e. Finally, it's not just the function keys, there are other keys that don't work too. Keys F7-F12 return one or sometimes several keycodes that are used by other keys. Keys F1 to F6 have no effect at all in evtest. The issue persists to this day, which is irritating, because other than several keys not functioning in Raspbian this keyboard works flawlessly it connects over BT rapidly after powering on without any hassle, it's small and easy to handle and has decent battery life.

Necroing this thread for anyone else with this keyboard.
