ERROR:Reject SCO: Agent not registered.

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?

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most of what you find on the web is outdated (like the link above) 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
http://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Modules/#index35h3

Regards
              Georg

I've found a way to use pc like an headset with Android phone (for making
callings).
!!! I've use pulseaudio from jessie-backports: I don't know how much this
takes risks ;-) !!!

In /etc/apt/sources.list add:

deb http://ftp.jp.debian.org/debian/ jessie-backports main contrib non-free
deb-src http://ftp.jp.debian.org/debian/ jessie-backports main contrib non-free

$ sudo apt-get update
$ sudo apt-get install pulseaudio=7.1-2~bpo8+1 pulseaudio-utils=7.1-2~bpo8+1 \
    pulseaudio-module-x11=7.1-2~bpo8+1
pulseaudio-module-bluetooth=7.1-2~bpo8+1 \
    libpulse-mainloop-glib0=7.1-2~bpo8+1 libpulsedsp=7.1-2~bpo8+1
libpulse0=7.1-2~bpo8+1 \
    libpulse0:i386=7.1-2~bpo8+1

create a file (with same ownership of /var/lib/gdm3) (create directories if
necessary)
/var/lib/gdm3/.config/pulse/client.conf

autospawn = no
daemon-binary = /bin/true

[http://www.gem.mydns.jp/daitei/linux/jessie/bt-headset/]


Install "ofono"

in /etc/pulse/default.pa 
modify the line:
load-module module-bluetooth-discover
in:
load-module module-bluetooth-discover headset=ofono

Restart pulseaudio:
killall -9 pulseaudio
(is not necessary "pulseaudio --start" because from pulseaudio 6 it will
restart automatically)

For now it seems that:
- if in /etc/pulse/default.pa you have add "headset=ofono" you will have the
headset;
- if not you will have a2dp (restart pulseaudio every time).

Good luck

UPDATES
About parameters of "load-module module-bluetooth-discover":
headset=native -> only a2dp
headset=ofono -> only headset
headset=auto -> a2dp and headset !!!

so in /etc/pulse/default.pa 
add "headset=auto" to line "load-module module-bluetooth-discover":

load-module module-bluetooth-discover headset=auto

It works!
