hi
I am trying to discover services on my cellular phone a Sony Ericsson k750
i. I am running ubuntu and the Bluez bluetooth protocol stack. I have
followed this example:
http://people.csail.mit.edu/albert/bluez-intro/x601.html
I have ofcourse changed the bluetooth address and the uuid to match my
phone and service. But still my program finds no services on the phone??
What is wrong here? Anybody have some hints?

Thanks
Markus

hi again
I have finaly found what my problem is, I am using:
uint32_t svc_uuid_int[] = {0x1c712d88, 0xaac711da, 0x818a000b, 0x0000ffff};
sdp_uuid128_create( &svc_uuid, &svc_uuid_int);

to create the service i am looking for. But something goes wrong using the
sdp_uuid128_create function I think. Using the uuid created returns nu
results. But using:
sdp_uuid16_create(&svc_uuid, 0x1002);

gives me a lot of results. I have dobbel checked that the uuid is correct
and that the service is running on my phone so why can i not use
sdp_uuid128_create()??
