Hi Georg,

Thanks for the quick response.

You should consider using ofono to connect your phone to the PC. It has all the
telephony functions you need and it works well together with PA. See here
for a short introduction:
https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Bluetooth/

I have tried using ofono for connection, but below error is coming continuously when call is initiated
$ /ofono/test/enable-modem

/Bluetooth: hci0 SCO packet for unknown connection handle 0/


As already said, I cannot help you much with the bluetooth stack related problems.



This looks like an error from the bluetooth stack, probably pulseaudio
cannot correct it. I experienced problems with some Bluetooth dongles,
have you tried another one?
I havent tried with other module, The Module which i am using is QCA6174A, which will support HFP profile as per documents. Do we need to route SCO audio as mentioned on section 5.0 in https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Bluetooth ? <https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Bluetooth/>


Some adapters have issues and need firmware or the correct audio routing.
If firmware is missing there should be something in dmesg.
I think you have to experiment a bit and maybe buy another dongle.
