Hi Denis,

Neither oFono nor BlueZ will enable the plugins for HFP support unless
DBus-1.3 is installed (or alternatively a hacked dbus-1.2 with file
descriptor passing support)

That explains a lot.

 
If you want this, then you will need to eventually write your own plugin
that will manage the RFCOMM and SCO sockets.  Today, BlueZ does this part...

I will look into that then. Thanks a lot for the response. This puts me back in the right track.

Regards,
