https://bugzilla.kernel.org/show_bug.cgi?id=219854 Bug ID: 219854 Summary: Bluetooth devices can't connect after toggling Bluetooth unless they are re-paired Product: Drivers Version: 2.5 Hardware: Intel OS: Linux Status: NEW Severity: normal Priority: P3 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: linux-bugzilla@xxxxxxxxxxxxxx Regression: No Created attachment 307785 --> https://bugzilla.kernel.org/attachment.cgi?id=307785&action=edit dmesg output on Linux Mint during reproduction of bug I noticed that my Bluetooth headsets would fail to reconnect to my NixOS laptop running `6.13.5` if I toggled (disable -> enable) the BT module. When this occurs, attempting to connect again via KDE's Bluetooth panel (or the Cinnamon BT applet in case of Linux Mint) would fail with a "Connection Failed" error. 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 regression 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-after-toggling-bt-unless-i-re-pair/61366) and that post contains some screenshots of the issue occurring on KDE, as well as `dmesg` output from the NixOS system (which seems to be more sparse compared to the Linux Mint output). This was tested on a ThinkPad T480 running the Intel Corporation Wireless 8265 / 8275 (rev 78) card, on NixOS-unstable `6.13.5`. I tested two headsets (Buds2 Pro / Sony WH-1000XM5) and they both "fail" in the same way. -- You may reply to this email to add a comment.
