Hi Michael,

your story is just too difficult to follow ... (or maybe it's just me)
You know mentioned about Synchronize but before you spoke about HF and HS=
...

anyway, as far as Synchonize profile is concerned, I have never used it.
(and I actually don't know if sdptool is able to create a record for it).
So you should check this first. If sdptool doesn't allow to create a reco=
rd
for synchronisation profile, you should directly use the bluez library=20
to create it.

And since (if I remember correctly) synchronisation profile is located=20
on the top of the OBEX layer you should use the openobex library and not
RFCOMM sockets directly.

Sincerely,

Alain

"sdp_main()" and then "socket()", "listen()", "bind()" and then "accept(=

by waiting the devices, especially T610, and then accept the connections=
?" Thank you very much.
