Description Ilya Bizyaev 2024-01-15 21:08:03 UTC

SUMMARY

When I log in to the Plasma session, Bluetooth is disabled (even though I've configured it to always be enabled on login through System Settings, but that's for another bug report). In the applet, Bluetooth is shown to be off, but my saved devices are still listed. Clicking “Connect” on any of them creates a push notification saying that “The device is not ready”.

Then I flip the switch to “on” and connect to the devices normally.

Disabling Bluetooth again does make the placeholder screen appear, so the issue only occurs after session startup.

OBSERVED RESULT
A list of my paired devices is shown in the Bluetooth applet when I log into the session, even though Bluetooth is disabled.

EXPECTED RESULT
The placeholder screen is disabled instead of the device list whenever Bluetooth is off.

When this happens, is Bluetooth in fact disabled? Or is the switch showing the incorrect state, and Bluetooth is actually enabled?

Comment 3 Ilya Bizyaev 2024-01-19 21:21:44 UTC

It is disabled, according to bluetoothctl > "show"
(because of https://bugs.kde.org/show_bug.cgi?id=479868)

Might be related. Actually, the switch in the header of the applet doesn't disable bluetooth. Here's the output of rfkill after "disabling" bluetooth using this switch:

> $ sudo rfkill list
> 1: tpacpi_bluetooth_sw: Bluetooth
>         Soft blocked: no
>         Hard blocked: no
> 2: hci0: Bluetooth
>         Soft blocked: no
>         Hard blocked: no

It's Neon User Edition, Plasma 6.0.0.

This is all very strange. Is anyone able to reproduce it with newer versions of Plasma, bluez, and the kernel?
