Hi Marcel,
   
  I have tried writing code to add the Additional Protocol Descriptor List. But it seems that the data still cannot be added as a 3-level sequence (sequence of a sequence of a sequence). The data I added for the Additional Protocol Descriptor List still look similar to the Protocol Descriptor List (2-level sequence of data).
   
  Here is the code corresponding to adding the SDP attribute:
   
  int sdp_set_add_access_protos(sdp_record_t *rec, const sdp_list_t *ap)
{
      const sdp_list_t *p;
  const sdp_list_t *pp;
  sdp_data_t *protos = 0;

  
  for (p = ap->data; p; p = p->next) {
    sdp_data_t *seq = access_proto_to_dataseq2(rec, (sdp_list_t *)p->data);
    protos = sdp_seq_append(protos, seq);  // protos = seq;
  }

  sdp_attr_add(rec, SDP_ATTR_ADD_PROTO_DESC_LIST, protos);
  return 0;
}


int add_additional_proto(void)
{

   /* Add Additional Protocol Descriptor List */
   sdp_uuid16_create(&l2cap_uuid, L2CAP_UUID);
   proto2[0] = sdp_list_append(0, &l2cap_uuid);
   apseq3 = sdp_list_append(0, proto2[0]);
   apseq2 = sdp_list_append(0, apseq3);

   sdp_uuid16_create(&rfcomm_uuid, RFCOMM_UUID);
   proto2[1] = sdp_list_append(0, &rfcomm_uuid);

   channel2 = sdp_data_alloc(SDP_UINT8, &chan2);
   proto2[1] = sdp_list_append(proto2[1], channel2);
   apseq3 = sdp_list_append(apseq3, proto2[1]);
 
   sdp_uuid16_create(&obex_uuid, OBEX_UUID);
   proto2[2] = sdp_list_append(0, &obex_uuid);
   apseq3 = sdp_list_append(apseq3, proto2[2]);
 
   addproto = sdp_list_append(0, apseq3);

   sdp_set_add_access_protos(&record, addproto);
  
   return 0;
}

   
  As you can see, I changed the attribute ID to correspond to SDP_ATTR_ADD_PROTO_DESC_LIST (0x000d) in the sdp_set_add_access_protos(). However, the data was not added correctly. I would like to ask in what other parts of the code should I make corresponding changes to add the sdp data correctly.
   
  Thank you for your time and efforts.

  Hi Arch,

you are welcome. I assume it is working perfect now.

And again Collin already ran into the same problem, 
because you also
need them for HID. So I think we need a 
sdp_set_add_access_protos()
function for this job. Feel free to send me a patch.

Regards

Marcel
