[pulseaudio-discuss] bluetooth headset and ofono backend

[Georg Chini]

Hello,

I am still fighting to get my bluetooth headset working properly
with the ofono backend. I cannot get HFP to work with pulse.

When I run ofonod and phonesim and switch on my headset
it seems to connect fine. A card turns up in pulseaudio but the
HFP profile is not available there. Trying to switch to the profile
leads to "not connected" messages in the log.
In phonesim I can simulate a call. If I do so, I get a ring in the
headset and can pick up the call. I am not sure if there is any
audio, I hear silence. If I am playing back with the a2dp_sink
profile at the same time, the a2dp audio is muted (but continues
playing).

Looking at the code I wonder if the HFP profile of a headset can
ever get available. The ofono backend listens for "CardAdded" or
"CardRemoved" DBUS-messages, but it seems that the "CardAdded"
signal is never emitted by ofono when a headset connects.
There is only a call to the associated function when a phone
connects and nowhere else in the code.
Or is there another way pulse is notified that the profile is available?
Did someone get it working and can tell me what I am doing wrong?

Regards
              Georg
