This patch changes the behavior of the headset=auto switch for
module-bluez5-discover.
With headset=auto now both backends will be active at the same time
for the AG role and
the switching between the backends is only done for the HS role.
headset=ofono and headset=native remain unchanged.
This allows to use old HSP only headsets while running ofono and to
have headset support
via pulseaudio if ofono is started with the --noplugin=hfp_ag_bluez5
option.
Not really related to the patch, I'm just curious: Does hfp_ag_bluez5
make ofono act in the AG role?
Yes, it does. However this only works if you have a modem in your system
or simulate one with phonesim. When I tested it (at least a year ago),
ofono
would support the AT commands of the headset, but audio did not work.
This is why I switched the AG support off.
Is the plugin loaded by default?
Yes.
Does
that work nowadays? Or is it still work in progress?
I'll pull a fresh ofono tree later today and check. The version on my
system
is rather old.
It still does not work in multiple ways. More detail:
- You need an enabled modem in your system before ofono exposes the
HFP AG role. This means you must at least have phonesim installed and
running and then use some D-Bus command to power on the simulated
modem.
- When the headset connects to ofono, you cannot switch the profile to HFP
using pulesaudio (it says "not connected", although the headset is
connected
to ofono)
- When I simulate a call with phonesim and ofono tries to pass the audio
connection to pulse, pulse crashes with an assertion:
module-bluez5-device.c: Assertion 'cp =
pa_hashmap_get(u->card->profiles,
pa_bluetooth_profile_to_string(t->profile))' failed at
modules/bluetooth/module-bluez5-device.c:2068, function
handle_transport_state_change(). Aborting.
I'm investigating why that happens.
So all in all I would say that the ofono AG role support is completely
broken
and I can only recommend to run ofono with the --noplugin=hfp_ag_bluez5
to disable it.
