Package: blueman
Version: 2.3.5-2+b1
Severity: important
After a fresh boot of the PC, sound is routed through hardware audio chip as
Profile: "Analog Stereo Duplex" selected in pavucontol (graphical Tool)
and works fine via pipewire and pipewire-pulse.
When I want to use my Headset (ear-buds with micro build in), i.e. to make a
phone call
using linphone I have to connect them via bluetooh to my adapter build in Intel
AX200 WiFi card.
Headset/ear-buds are "Hama Freedom Light" with bluetooth 5.1 supporting these
profiles:
A2DP v1.3
AVRCP v1.5
HFP v1.5
SPP v1.0
Connection fails when performing the usual way using blueman after pairing and
trusting.
Blueman reports (auto-)"connected", but the device is not available for
selection,
neither in linphone, nor in pavucontrol.
I tried various settings in /etc/bluetooth/main.conf without any success.
But I found a dirty workaround by watching bluetooth messages and "try and
error".
Executing the interactive "bluetoothctl" command shows following.
ingo@xpc:~$ bluetoothctl

Additional info:
When blueman reports "connected" at the first discovery of my ear-buds nothing
is logged in system journal.
When I then issue the "bluetoohtctl connect 3C:F8:A8:B9:CE:A1" comand another
time to comlpete setup,
journal logs:

I do not have the knowledge for further debugging this complicated bluetooth
attitude.
My guess currently is, the first auto-connect is with AVRCP profile only and
the ear-buds are
waiting for further information and/or callback. The second (manual) connect
then registers the
selected profile and completes connection.
