When this occurs, attempting to connect again via KDE's Bluetooth panel (or the Cinna= mon BT applet in case of Linux Mint) would fail with a "Connection Failed" erro= r. The only way to fix this is to unpair the devices, then re-pair them and connect to them again. Then BT will continue to work until the module is toggled and/or the laptop enters sleep (I guess the module gets power-cycled during sleep). Under Windows this does not occur. On a live Linux Mint boot running kernel `6.8.0-51-generic` the same issue occurs. I am not sure if this is a regres= sion or not as I have not tested earlier versions of the kernel. Attached `dmesg` output from the Linux Mint reproduction, after toggling the module on and attempting to connect to the previously paired device. I also posted about this on the NixOS forums here (https://discourse.nixos.org/t/cant-reconnect-to-paired-bluetooth-devices-a= fter-toggling-bt-unless-i-re-pair/61366) and that post contains some screenshots of the issue occurring on KDE, as w= ell as `dmesg` output from the NixOS system (which seems to be more sparse comp= ared to the Linux Mint output). This was tested on a ThinkPad T480 running the Intel Corporation Wireless 8= 265 / 8275 (rev 78) card, on NixOS-unstable `6.13.5`. I tested two headsets (Bu= ds2 Pro / Sony WH-1000XM5) and they both "fail" in the same way. --=20 You may reply to this email to add a comment.
