            Bug ID: 483485
           Summary: Bluetooth pairing via GUI fails/Freezes on some
                    devices
    Classification: Plasma
           Product: Bluedevil
           Version: unspecified
          Platform: Neon
                OS: Linux
            Status: REPORTED
          Severity: minor
          Priority: NOR
         Component: general
          Assignee: now...@gmail.com
          Reporter: julino.developm...@online.de
                CC: plasma-b...@kde.org
  Target Milestone: ---

SUMMARY
Tried to pair any bluetooth device via the tray or via system settings on my Hp
Omen 16 (2023) Laptop with  Intel AX211 Wireless card does not work. When
clicking on next in the add new device window, the progress bar freezes and
afterwards the pairing fails.
This is sometimes by a message 
bluedevil-wizard[4537]: kf.bluezqt: PendingCall Error: "Did not receive a
reply. Possible causes include: the remote application did not send a reply,
the message bus security policy blocked the reply, the reply timeout expired,
or the network connection was broken."
or
"Authentification cancelled"
Manual Pairing via. bluetoothctl does not work when discovery is enabled.
Disabling this makes pairing possible. In the GUI pairing window, discovery is
enabled all the timing.

(I do not know if this is a bluedevil issue or should be fixed in a lower
layer. But at least it gave me a frustrating experience)
Recommendations:
- Add a possibility to stop discovery (e.g. there is already the scanning
indicator. Maybe introduce a button to stop discovery)
- Disable discovery prior to trying to pair with a device



STEPS TO REPRODUCE
1. Probably only with my bt card
2. Open "Add New Device..." via tray or settings gui.
3. Try pairing with arbitrary device

OBSERVED RESULT
Window freezes and pairing just fails.

EXPECTED RESULT
Pairing working when clicking the button. No Freeze. A more meaningful error
when something fails...
