Hi, I bought a bluetooth keyboard but despite doing the connection procedure, which apparently is successful, the keyboard does not work. I have tried several times without success and trying it with windows 10 it works. Ubuntu Mate 20.04.2, [KVAGO keyboard for Tablet 10.4" Samsung Galaxy Tab A7 2020 SM-T505/T500/T507,keyboard Bluetooth Wireless],ASUS S550CB.
Solutions?
