Hello Norbert,

you should be using pulseaudio from the current git. Pulseaudio version 5.0 and below do not support HFP in combination with Bluez5. I am running Bluez 5.23 from Debian unstable and a recent ofono and pulseaudio compiled from source. This
works fine for my mobiles.

Hi Norbert,

Please don't top-post on this mailing list. That's just our convention here. Anyway, see below:

Hi Denis,

now I have installed ofono from the debian jessie testing branch (which
has packaged ofono 1.15-2). Bluez is still version 4.99 and all the rest
is debian wheezy as before. Now the list-modems.py script does not show
any modem any more. Are there dependency issues?


BlueZ4 requires --with-bluez4 when configuring oFono.

I already had tried a combination of ofono 1.15-2 and Bluez 5.23, which
was quite promising. I could successfully establish a phone call by
means of the dial-number.py script. But there was no voice connection
established between the endpoints. This was quite astonishing because
A2DP streaming from the smartphone to the Raspberry Pi worked like a
charm. And I don't think that it was a phone issue because a HFP
connection from the phone to a navigation device works well too.


oFono and BlueZ are not the only ones at play. The audio is handled by PulseAudio. So I would check on the PulseAudio mailing list which version of PulseAudio you need.

I have read somewhere that Bluez5 does not support HFP at all, so I did
not further follow this approach.

Correct, sort of.


Any proposal which combination of ofono and Bluez is most promising in
order to establish a HFP voice connection?


As mentioned before, BlueZ and oFono are not the problem here. Check back with PulseAudio folks.

Regards,

Ups, sorry for making the same mistake as Norbert. Anyway, you also have to load the module-bluetooth-discover with the parameter headset=ofono, so add this in default.pa
