Problem,
I have seen that there is a function named sdp_service_search_req,
So,I append two service uuid such as obexpush's uuid and another
service's uuid into the search list, I want to get the two services' info
only call search func once.
and then set the max_rec_num = 2,
then call
sdp_service_search_req(session,search_list,2,&rsp_list);
but ,I have seen that the func return 0, but the rsp_list is NULL.
Who can you tell me why?
thank you.

I would propose you run "hcidump -X -V" as root while you are trying
this and then show us that output.
