SCO control in HansfreeGateway

SCO control in HansfreeGateway

[Mikel Astiz]

Hi all,

Some recent patches have made that the State property in 
HandsfreeGateway exposes if the SCO connection is active or not. As far 
as I understand, the state Playing is specifically added for this reason.

However, I don't see any way in the D-Bus API to control the state of 
this connection. One example would be that a phone would drop the audio 
connection (it is allowed to do so at any time) but the user wants this 
connection to be re-established.

Wouldn't this require the addition of some methods like ConnectAudio and 
DisconnectAudio in the HandsfreeGateway interface?

Regards,
Mikel

If you want to control the connection then you need to use the unix
socket or register a endpoint with org.bluez.Media.RegisterEndpoint
(recommended), for the latter you need this is your audio.conf

Enable=Media
Disable=Socket

There is some documentation about it in doc/media-api.txt and a test
script test/simple-endpoint

Nope, this was why we also deprecated Headset.Play/Stop, it is not up
to the application to decide when to connect but to the endpoints e.g.
if you are using PulseAudio make use of set_profile.
