[SOLVED] Bluetooth refuses to connect to keyboard

Hello. I have been using my bluetooth keyboard to switch between my arch and Windows laptop without any issues until yesterday, when i updated my arch system and after rebooting, bluetooth will refuse to connect to my keyboard. i have tried re-pairing it, but it will connect momentarily before disconnecting again. Interestingly this doesn't affect other bluetooth devices such as my speaker and phone, which connect and function without issue. i have since tried deleting /var/lib/bluetooth, switch off and restart bluetooth.service but am still stuck with this problem and am clueless as to how to proceed further. any help will be much appreciated.

bluez sometimes has regressions, you're likely hit by one, try to downgrade bluez to 5.79: https://wiki.archlinux.org/title/Downgrading_packages

That fixed it, thanks! Ive downgraded to bluez 5.79 and my keyboard is working like normal again! The question now is, do i avoid updating bluez until a newer version is out?

That's the approach you could take, a better one would be to gather logs of your exact issue and report it to the bluez devs so it can get fixed.  There's already a bigger discussion on similar issues here: https://github.com/bluez/bluez/issues/1138 with https://github.com/bluez/bluez/issues/1 … 2741495921 being particularly interesting which would allow you to set a config option.
