Hi all. trying to use some bluetooth headphones and struggling to connect them.
Bluetooth works fine on Windows and, as far as I can tell, should be working with linux…
Any ideas for next steps? I’m relatively new to linux… I’ve reached the limit of my google/chatGPT finds.
Any help appreciated!!!

most bluetooth controllers are USB, run the command lsusb -v and look for a USB controller.
On my desktop computer I have a USB bluetooth controller in a SDcard reader 3.5 inch floppy disk driver format insert in the computers case, and it gives me the following (only top few lines shown as its quite long)

and the systemctl status is as follows.

and mine is working fine, via KDE’s bluetooth panel.
update quick look on your board and I believe the wifi module is an The Intel AX210 chipset.
if thats correct its not supported until kernel 5.10 so an upgrade to rocky 9 may be the simplest solution.
Sorry I missed this, I appreciate the reply. it’s actually mediatek, not Intel. I am considering switching to 9. thanks for the input. One distint difference between our output above is when you run ‘show’ for bluetoothctl, you get a controller. mind can’t fine the controller. I’m assuming that’s the root of it.
same problem then as the intel i mentioned
needs kernel 5.17 as detailed in this link
as that will be the MT7922A22M acording to searches i have found.
then i searched to check if you can install 5.17 on rocky 8 (well i searched on rhel8/centos 8, but you get the jist.
and i found this.
so rather than do all that work to see if it fixes your problem why not try an upgraded kernel first and see if that fixes the problem, then you can consider EL9 upgrade, but hold off a few people have been having issues with 9.2, so may be worth seeing if that problem resolves itself and just get the kernel for now.
