please do a "hcitool info <k700i>" as root for me and use the sdptest
program from the libs2 CVS repository to get me the full SDP records.

You don't need to install the libs2 stuff. Only check it out and compile
it with "./bootstrap && ./configure && make". After that you should call

	./test/sdptest records k700i-bdaddr > sdp_records.txt

and then send me the sdp_records.txt file. The output from "hcitool inq"
will also be nice to see what kind of class of device they are using.

>>From the hcidump I see a problem with connecting to the SDP PSM. It
seems that this is disabled when HID is in use and this phone has a
stupid L2CAP implementation that reacts weird and we do the same. But
for you it responds with "Connection refused - no resources available"
and this is great. They offer HID support and can't have three L2CAP
connections at the same time. That is totally stupid.

I need such a phone to tweak around the L2CAP problem and get the hidd
working without retrieving the SDP record. Any sponsor out there?

And btw do you enabled auth and encrypt in hcid.conf? Don't do so unless
you really wanna use security mode 3.

Regards

Marcel
