[Bluez-devel] sdp seq of raw data

["Collin R. Mulliner" <collin@betaversion.net>]

Hi Marcel and list,

I'm trying (for hours now) to put a raw binary string into a sdp
attribute so that it shows up like this:

---8<----
Data Sequence
      Data : 0B 0X 09 06 a1 01 85 01 05 07 19 e0 29 e7 15 00 25 01 75 01
95 08 81 02 75 08 95 01 81 01 75 01 95 05 
05 08 19 01 29 05 91 02 75 03 95 01 91 01 75 08 95 06 15 00 26 ff 00 05 
------>8------

I have tryed two methods, both failed:

SEQ8 method:

unit8_t h_spec[] = { binary_crap };
uint8_t dtd2 = SDP_UNIT8;
uint8_t dtd_data = SDP_SEQ8;
void *dtds[2];
void *values[2];


// this is a other uint8 value which gets placed correctly
dtds[0] = &dtd2;
values[0] = &h_spec_leng;

for (i = 0; i < sizeof(h_spec); i++) {
 h_spec_data_lst[i] = sdp_data_alloc(dtd2, &h_spec[i]);
 h_spec_data_dtds[i] = &dtd_data;
}
// sometimes it crashes here...
h_spec_data_list = sdp_seq_alloc(h_spec_data_dtds, 
  (void**)h_spec_data_lst, sizeof(h_spec));

dtds[1] = &dtd_data;
values[1] = h_spec_data_list;
// sometimes it crashes here
h_spec_lst = sdp_seq_alloc(dtds, values, 2);
sdp_attr_add(sdp_record, SRV_ATTR_1, h_spec_lst);

// and sometimes the attributes added after this one don't get
displayed, and the binary string is only one byte long


TEXT_STR8 method:

works fine but can't use binary, because of strcpy/strlen in sdp part of
libbluetooth


I couldn't find any matching example in all the BlueZ code...

thanks ... Collin

It's a hardware problem!
