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/ file
bluetooth-headsets-media-api.
Recompiled the raspbian kernel with
*CONFIG_BT_SCOCONFIG_BT_HCIUSB_SCO*
enabled
Added
*Enable = Source,Sink,Headset,Gateway,Control,MediaDisable = 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_gatewayFailure: 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?
