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.
 
My func named getService() which uses sdp_service_search_req

int BTWorker::getService(Device * pDev)
{
  int CPS_err;
  sdp_list_t *CPS_r,*next;
  sdp_record_t *CPS_rec;
  sdp_list_t *CPS_proto_list;
  bool bFound=false;
  uint8_t numoffound=0;
  uint8_t rfcommChannel;
  uint8_t obexChannel;
  char desc[100];

  bdaddr_t source;//the source dongle should be saved in the adaptor, you should config it in the ap.ini
  bdaddr_t target;
  str2ba(pDev->getDeviceAddress()->getAddress_str().c_str(),&target);
      sdp_session_t *session = 0;
  str2ba(adaptor->getAddress()->getAddress_str().c_str(),&source);
  // connect to the SDP server running on the remote machine
  session = sdp_connect_custom(&source,&target,SDP_RETRY_IF_BUSY);
  if(session==NULL)
  {
      return -1;
      }

  // specify the UUID of the application service(s) we're searching for
  uint16_t CPS_svc_uuid_int=CPS_SERV_UUID;   // 0x2222
  uint16_t OBEX_svc_uuid_int=OBEX_SERV_UUID; // 0x 1105
  uuid_t CPS_svc_uuid;
  uuid_t OBEX_svc_uuid;
  sdp_uuid16_create(&CPS_svc_uuid, CPS_svc_uuid_int);
  sdp_uuid16_create(&OBEX_svc_uuid,OBEX_svc_uuid_int);

  sdp_list_t * CPS_search_list;
  CPS_search_list = sdp_list_append(NULL,&CPS_svc_uuid);
  CPS_search_list = sdp_list_append(CPS_search_list,&OBEX_svc_uuid );
  
  // specify that we want a list of all the matching services' attributes

  uint16_t rec_num =2;
  // get a list of service records that have UUID CPS_SERV_UUID + OBEX_SERV_UUID
  sdp_list_t *CPS_response_list = NULL;

  // search
  
   CPS_err = sdp_service_search_req(session,CPS_search_list,255,&CPS_response_list);
  
  printf("CPS_err is %d\n",CPS_err);
  if(CPS_response_list == NULL)
   printf("Rsp is NULL\n");
  sdp_list_free(CPS_search_list,0);
  sdp_close(session);
  //...............other..................
}

My program's output is:

CPS_err is -1
Rsp is NULL
NO CPS or OBEX svc founded
Get service failed!00:12:D1:D1:08:47

The HCIDUMP -X -V output is:
