Hi,
I am trying to configure HFP with Bluez(5.34), Ofono(1.17) and
pulseaudio(6) on a Freescale i.MX6 board using Linux 4.1.15 kernel,
the idea is to use the target board in HFP/Handsfree Unit role. The
bluetooth controller is a Pluggable USB Bluetooth Dongle (0a5c:21e8
- BCM20702A0) with updated firmware.
The procedure followed is,
* Pair & connect with the android mobile phone with the bluetoothctl
* Enable modem and dial number using ofono test scripts
After this the call is being made but the audio routing fails with
"Reject SCO : Agent not registered" message from oFono. While
checking with btmon its found that the SCO Connect Request has been
rejected with the reason of limited resources(0x0d).
Can anyone help me to identify the root cause, I spent a lot of
time trying different version combinations, loading firmware and
checking logs but still nothing.
This looks like a problem with PulseAudio configuration. oFono does not
handle SCO data, PulseAudio does that. In order to do that, PulseAudio
needs to register an agent with oFono. Then the SCO socket will be
established and the fd handed off to PulseAudio to process the audio data.
I have no idea how this is accomplished in PulseAudio. This question is
being asked fairly often recently. Does PulseAudio have an
FAQ/documentation for this yet?
In /etc/pulse/default.pa, add parameter headset=ofono to module-
bluetooth-discover. That should be all that's needed at PulseAudio
side.
Denis, would you be willing to help me with the oFono parts, if I write
a document explaining how to make bluetooth audio work with
BlueZ5+PA+oFono?
Sure.
Regards,
-Denis
