Since the latest upgrade of bluez to bluez-5.73-3.fc39.x86_64 the plasmoid/widget for bluetooth does not show connected devices any more, although they are (still) connected and working. (that's what i assume, as this is the only bluetooth related upgrade since then) Typically, the bluetooth/widget icon is surrounded by dots (--B--) if a device is connected. Strangely, the battery information (here: for my headphone) is shown correctly, but the widget does not toggle the 'connect/disconnect' button to the connected-state. I also cannot 'disconnect' a device using the widget A second connected device also does not show in the list as 'connected' But, both devices are active and visible in pavucontrol and play sound quite happily :-D Operating System: Fedora Linux 39 KDE Plasma Version: 5.27.11 KDE Frameworks Version: 5.115.0 Qt Version: 5.15.12 Kernel Version: 6.8.4-200.fc39.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 PRO 7840U w/ Radeon 780M Graphics Memory: 58,6 GiB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: LENOVO System Version: ThinkPad P14s Gen 4
additional info: bluetoothctl devices Connected does not show those active and connected devices either... (i am testing with jabra and musicbox) But, they are in the 'paired' list as expected bluetoothctl devices Paired Device 50:C2:75:17:06:2A Jabra Evolve 65 SE Device 28:11:A5:74:D4:70 Bose QC35 II Device CC:90:93:07:3B:09 musicbox XS 3B09
so, i downgraded to bluez-5.69-1.fc39.x86_64 and upgraded again to bluez-5.73-3.fc39.x86_64 and now it seems stable, 'bluetoothctl' and widget do their job as expected. Maybe some upgrade problem (package definitions?) I'm inclined to close this but if there are no objections?
Indeed, sounds like an upstream library was to blame.
It reappeared after some reboots. Maybe the closing was too early... Meaning: plasma-applet does not show the dots (--B--) and does not show the connection state "bluetoothctl devices Connected" show no connected devices but: everything works (jabra headphone works as active BT connection)
i did the same approach as last time... downgrade, update again. But, the situation did not improve, bluetoothctl does not show the connected devices, nor dos the plasma applet (still i have an active connection and audio for the headphone works) This is some other error we have here ... What kind of logs do you need to investigate?
found this in the meantime: https://bugzilla.kernel.org/show_bug.cgi?id=218680
I see the upstream bug report was closed, with a fix merged. I'll close this out for now. If you're still seeing the exact same issue, in Plasma 6.4.4. or later, feel free to reopen it. Keep in mind, however, that if bluetoothctl can't show the device, the problem isn't in Plasma it is indeed in the kernl.
