Marcel,
Thanks for the feedback. Upgrading to 3.33 resolved the immediate problem with accessing UUIDs, and I do get the correct UUID from
the remote (hurray!).
FWIW, with SSP I intend to use only the "Just Works" model at this point, keeping the handshake as simple as possible (not a highly
secure application). So, the capability parameter will be "NoInputOutput", if I am reading the code correctly (adapter.c).
Hopefully, that will "JustWork", and I can proceed with the effort I originally undertook. At any rate, I will be watching CVS
closely...
All the best, and good luck with that server. It always seems that just when you think you can trust a system's to be reliable,
that's when the hard drive crashes...

the CreateDevice needs some more magic in case the remote device has no
public browse group.
Currently we have in device.c the following struct:
static uint16_t uuid_list[] = {
PUBLIC_BROWSE_GROUP,
HID_SVCLASS_ID,
GENERIC_AUDIO_SVCLASS_ID,
ADVANCED_AUDIO_SVCLASS_ID,
AV_REMOTE_SVCLASS_ID,
0
};
So in case the public browse group fails, it will go through the list of
additional UUIDs and search for them. So your AVRCP case should be
handled.

So DiscoverServices will update the UUID list of course, but normally
there should be no need to call it. CreateDevice needs to be fixed to do
the right job.
The DiscoverServices is mainly for applications that need access to the
full service record. Stuff like obex-data-server for example.

Yep. We are almost done with. However you will need kernel changes to
make this work.

I wanna do the release actually today.
