Bluetooth for Dune HD R4 remote

Received my new Dune HD R4 remote control, yesterday. How would I get a Bluetooth driver for this device.
I was able to get the “Homatics-B21-local-keyboard.hwdb” to work for just the basic functions, except the “enter” button.

You don’t need driver: only hwdb fix. Like this: Report about Amlogic S905X4 HK1 RBOX X4 - #217 by hungphutho
