            Bug ID: 218680
           Summary: bluetooth connected status not shown in KDE desktop
                    GUIs
           Product: Drivers
           Version: 2.5
    Kernel Version: 6.8.2
          Hardware: Intel
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Bluetooth
          Assignee: linux-bluetooth@vger.kernel.org

           Bisected 81526f2920bf8a03b670dbc2d45f35f204344d55
         commit-id:

Since 6.8.2 bluetooth connected status is not shown any more in KDE desktop
GUIs: it looks disconnected but in fact is connected and working (bluetooth
headset).

$ systemctl status bluetooth
bluetoothd[413]: Authorization request for non-connected device!? (in RED)

The "Authorization request for non-connected device!?" also appears in the
journalctl output.


It turned out that commit "81526f2920bf8a03b670dbc2d45f35f204344d55" is
responsible for this malfunction: I made an Arch Linux package build for
6.8.2.arch1-1 with this single commit
"81526f2920bf8a03b670dbc2d45f35f204344d55" reverted and it worked again. So
"81526f2920bf8a03b670dbc2d45f35f204344d55" is the one and only cause for this
malfunction.

    Bluetooth: hci_event: Fix not indicating new connection for BIG Sync

    [ Upstream commit eeda1bf97bb500a901f7a9ee5615bad2160f2378 ]

    BIG Sync (aka. Broadcast sink) requires to inform that the device is
    connected when a data path is active otherwise userspace could attempt
    to free resources allocated to the device object while scanning.

    Fixes: 1d11d70d1f6b ("Bluetooth: ISO: Pass BIG encryption info through
QoS")
