Description Patrick Silva 2024-02-25 00:03:04 UTC

STEPS TO REPRODUCE
1. pair a laptop and an android phone
2. reboot the laptop
3. make sure the android phone is unlocked and its bluetooth feature is activated
4. try to connect the laptop to the previously paired android phone via Bluetooth applet

OBSERVED RESULT
apparently the laptop was connected (the label of the button of the applet changes to "Disconnect" from "Connect" and we do not see any error message), but the android phone does not detect any connection between the devices

EXPECTED RESULT
the devices should connect, and we should receive some feedback in case of connection failure

Can you reproduce it in Plasma 6.3.4 or later?

Comment 2 Patrick Silva 2025-04-17 12:22:55 UTC

I'm unable to test; my laptop broke a few months ago. Feel free to close if you are unable to reproduce too.

Comment 3 Nate Graham 2025-04-17 17:01:19 UTC

Oh no, that's no good! I can't reproduce it, yeah.

This screenshot shows the originally reported bug. The button of the applet is labeled "Disconnect" despite the device was not connected. The main problem is a connection failure.
