Hi All, Sorry if I have posted this twice. Put last time I did not see my mail come trough the mailing list. I have used your examples in dund.c to make a proper SDP client that can advertise my protocol (L2CAP) and PSM correctly to the sdpd daemon. All the attributes looks correctly and functions ok. My question is now: How do I update my SDP record (more specifically the PSM attribute)? I can't find any example or anything. Explaination or example files are appriciated! :-) Thanks in advance.. /Steffen Larsen
