Switching profiles

Hi,

I have a device that supports multiple profiles (headset_head_unit/a2dp_sink) and I would like this mode to handle switching between them so that I can stop using pactl.

I found that the Device API has ConnectProfile method that accepts a "remote service UUID for the profile" but I'm stuck because I have no idea how to get this UUID. I see the profiles in bluetooth-show-device-info output but nothing I try seems to work.

I think the ability to display the active profile and to switch between them would be a useful addition for this project.
