Hello,

can someone help me with the problem below? Is ofono supposed
to expose an audio card when a headset is connected? If so, could
you explain how this happens?
I am not using SELinux and have ofono and pulse compiled from a
recent source. The rest of the system is Debian unstable witch ships
Bluez version 5.23.

If this is not the right place to ask such questions please tell me, I
never received any response to my previous mails.

Regards
              Georg

I have no idea what SELinux would have to do with anything...

What exactly are you trying to do? Phonesim can only simulate modem 
signaling.  It will _not_ generate audio.  I should also point out that 
oFono does not support audio for HFP AG role with BlueZ 5.

Only HFP Handsfree role with BlueZ5/PulseAudio is supported.

Yes, as I said previously, what you're trying to do is not supported.

Hello Denis,

thanks a lot for the information! That was what I was looking for.

Bluetooth headset and ofono

[Georg Chini]

[-- Attachment #1: Type: text/plain, Size: 1746 bytes --]

Hello,

I have trouble getting my bluetooth headset to work with ofono and 
pulseaudio.
My mobile phones connect without problems and work fine.

First, I do not have a modem in my system, so I installed phonesim. 
Bluez Version
is 5.23 (Debian unstable), pulseaudio and ofono are compiled from 
current git.
When I run phonesim and power on the modem I see that UUID 0x111f is 
available.
When I power on my headset (which is already paired and trusted and HSP 
works
OK with the pulseaudio native backend) it is connected, but I cannot use 
the HFP
profile. Log messages from ofono are:

plugins/hfp_ag_bluez5.c:profile_new_connection() Profile handler 
NewConnection
plugins/hfp_ag_bluez5.c:profile_new_connection() 
/org/bluez/hci0/dev_0C_E0_E4_31_23_2D
plugins/hfp_ag_bluez5.c:profile_new_connection() Picked modem 0x1d64640 
for emulator
src/emulator.c:ofono_emulator_create() modem: 0x1d64640, type: 1
src/emulator.c:ofono_emulator_register() 0x1d52220, 14

And when I disconnect the headset, I get:

src/emulator.c:emulator_disconnect() 0x1d52220
src/emulator.c:emulator_unregister() 0x1d52220
src/emulator.c:emulator_remove() atom: 0x1d669c0
plugins/hfp_ag_bluez5.c:io_hup_cb() Remove 
/org/bluez/hci0/dev_0C_E0_E4_31_23_2D
plugins/hfp_ag_bluez5.c:connection_destroy() fd 15

I see no D-Bus messages at all, I would expect something similar to the 
messages
I get when I connect my mobile. Headset is a Plantronics Backbeat Pro.

In pulseaudio the headset turns up, but only the a2dp profile is 
useable. The a2dp profile
is connected after HFP. When I try to switch to HFP, pulsaudio says the 
HFP profile is not
connected.

Any idea what I am doing wrong?

              Georg
