Responsiveness of UR01 remote control

I recently got the Ugoos AM6B plus - the remote UR01 is not very responsive. I copied the right file in /Storage/.config/. It seems that by default the RC works in IR. It frequently stops working and interact with other component (my SONY TV). I would prefer to work in Bluetooth, but I can’t pair the RC in CoreElec settings menu (I put the 2 antenas). Does somebody have a workaround to solve this issue? Thanks for all.

Everything is alright today. Forget it. Sorry.
