Hello and a Happy New Year,
I'm new in the community and I have a problem with my Bluetooth. It seems to works and scanning, but it doesn't find any of the nearby devices. I haven't found something helpful from different articles on the internet.
I think that my Bluetooth it's on my network controller atheros ar9285 with kernel ath9k and I have Ubuntu 20.04.6 LTS.

Do you have any idea that can I do to fix this issue?
Thanks!

I want to add that when I had windows, Bluetooth was working normally.
If it helps this is the specifications for my laptop:
