I forgot to add, suspending of the sink/source seemed to cause
disconnection by the AG, so you might want to disable
module-suspend-on-idle when testing. BTW, Lennart, is there any way to
mark a source/sink to not be suspended?

Create the 'Handsfree Gateway' profile for bluetooth cards and add
filters for 'org.bluez.HandsfreeGateway' to the discover module so
module-bluetooth-device is loaded with the correct profile when a
Handsfree Gateway connects to bluetoothd (in this case bluetoothd
is acting as the headset).

I think loading module-bluetooth-device only when there is an active
call can be a good solution. But I'm concerned about other audio
events, i. e.: ringing, SMS notification etc.: doesn't the AG
establishes a SCO channel for the these events? Also, I don't think
pulse should listen to ofono signals, it should be agent-agnostic. But
a signal could be added to the agent interface in this case.
And I'm not sure if automatically loading module-loopback is a good
idea, I think we better expose through the UI how to handle the audio
stream. Some users may have a bunch of soundcards or some very weird
audio setup, and it's up to them to decide which soundcard to connect
the HFP stream.

Yep, Media API is supposed to handle this, that why I asked them to be
though in an integrated manner maybe being registered in the same
interface (although hfp is not really media only), anyway basically we
should have pa acting as a2dp source/sink and/or hfp gateway/headset
endpoint handling the audio. So in essence ofono is acting as a
controller/target in a very similar way as avrcp does for a2dp,
although for avrcp we don't really need an agent as we use uinput.

The output from bluetoothd likes below:
bluetoothd[21141]: Accepted AG connection from 00:BD:3A:D4:4E:53 for
/org/bluez/21141/hci0/dev_00_BD_3A_D4_4E_53
bluetoothd[21141]: Accepted SCO connection from 00:BD:3A:D4:4E:53

bluetoothd[21141]: sco connection is released
I think you should not load module-bluetooth-device until a voice call
is started, no matter incoming or outgoing. Because PA may play music
from other device at the same time. And bluetooth-device and loopback
module are loaded together. According to HFP v1.5 4.13, there are two
cases for incoming call. And outgoing call is simpler than incoming call.
If AG and HF both support in band ring tones, we should send a signal
from oFono to PA when callsetup=1. If not, we should send it when call=1.
I had a patch originally but I cannot find it now. :-(. The basic idea
is to add a filter in ciev_notify() to emit signal (CallStarted and
CallEnded) to PA. And PA loads module once it got that signal. Maybe the
signal name was bad and you could choose better one as you want. ;-)
Thanks.

Good work! Looks like it works pretty fine. :-). At the last of video, I
saw you load loopback module manually. Zheng Huan made a patch to load
loopback automatically. I believe Padovan has a copy of that. You may
also integrate it with upstream.

AFAK, the SCO connection request is from AG side and BlueZ will check if
no SCO stream comes from AG(??), it will shutdown the connection. In my
memory, I don't get POLLHUP event in my original patch. You can turn on
debug flag to see more BlueZ output.

Just updating, this patch actually worked when testing with a
different adapter (Fujitsu-Siemens CSR-based). The adapter causing
problems was a Broadcom 2.1, the internal adapter of a Dell Mini10.
Also, suspending the source / sink actually doesn't interfere.
I did a small video of the whole stuff: http://www.vimeo.com/9078799
There are still some problems when testing against Nokia N900 and
2660. After the "enable-modem" step, the RFCOMM link is connected and
the SCO just after that, leading module-bluetooth-discover to load
module-bluetooth-device. Sometimes after that the polling on the
stream fd get a POLLHUP and the module-bluetooth-device unloads
itself. Other times the POLLHUP doesn't happen and the remaining steps
go without any problem.
Ideas on how to improve this scenario will be very helpful.
