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

success. But what I found disappointing is I cannot find any service in t=

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

becomes "how can I link the SDP setting and socket programming of the ser=
ver together so that the SDP service can be added in my Linux PC followed=
 by waiting the devices, especially T610, and then accept the connections=
?" Thank you very much.
