Hi,
I was trying to setup HFP uing ofono. I have the following setup
Rasperry Pi B+ ( ARM1176JZF-S)
Bluez 5.32
Pulseaudio 6.0
ofono 1.16
Used the following steps
http://padovan.org/blog/2010/02/handsfree-profile-into-bluez-and-ofono/
start pulseaudio, bluetoothd and ofonod
Connect to phone using bluetoothctl
./enable-modem
./dial-number
loopback
I was able to pair my nexus 4 device and use the script ./dial-number
which actually sets a call up. But the audio of the call doesn't route
to the default sink. I see the following error in ofonod
/
Reject SCO: Agent not registered/
Which could be the reason for the audio problem.
Things that I have already tried.
Patched http://cgit.freedesktop.org/~jprvita/pulseaudio/
<http://cgit.freedesktop.org/%7Ejprvita/pulseaudio/> file
bluetooth-headsets-media-api.
Recompiled the raspbian kernel with
/CONFIG_BT_SCO
CONFIG_BT_HCIUSB_SCO/
enabled
Added
/Enable = Source,Sink,Headset,Gateway,Control,Media
Disable = Socket/
to /etc/bluetooth/audio.conf.
Things that could be wrong
When I do a pactl list cards, i see the bluetooth card at #0 with two
profiles.
/
Profiles:
a2dp_source: High Fidelity Capture (A2DP Source)
(sinks: 0, sources: 1, priority: 10, available: yes)
headset_audio_gateway: Headset Audio Gateway (HSP/HFP)
(sinks: 1, sources: 1, priority: 20, available: no)
off: Off (sinks: 0, sources: 0, priority: 0,
available: yes)
Active Profile: a2dp_source
/
But when I try making the headset_audio_gateway the default profile. I
get
/$ sudo pactl set-card-profile 0 headset_audio_gateway
Failure: Input/Output error/
Also read this in the pulseaudio notes
http://www.freedesktop.org/wiki/Software/PulseAudio/Notes/6.0/
"When building PulseAudio, it's possible to choose between "native"
and "ofono" BlueZ 5 headset backends."
How do I specify that I wish to use the ofono headset backend? Is that
the problem?
Hi,
most of what you find on the web is outdated (like the link above)
because it refers
to Bluez 4 which has a completely different API compared to Bluez 5. But
nevertheless
the combination you are using should work. In pulseaudio you have to
enable ofono
support by adding the parameter "headset=ofono" to
module-bluetooth-discover in
default.pa. See also
