Hi Marcel,
I am having a problem adding the 1284ID attribute. The 1284ID is of type String. (So I use SDP_TEXT_STR8) However, the first 2 characters of this string are to be interpreted as a 2-byte length field. The length of my string is 80 which is 0x0050 in HEXADECIMAL. So when I add it as a string, the SDP function interprets the 1st byte as a null terminator and sends an empty string.
I tried increasing the length of my string to 0x0101 to avoid a 0x00 byte. However, this cannot be done since the maximum length for an SDP_TEXT_STR8 is only 255 which is 0x00FF.
In this case, how will I be able to add a 1284ID string attribute whose length field contains a 0x00 byte?
Thanks,
Arch Sayo

Hi Marcel,
I'm having problems like this too. I cant add a 1248
id because of 0x00 that I assume is interpreted by the
bluezstack as a null terminator.
Thanks!

Hi Marcel,
I'm still having problems with the 1248 id. I already
used the bluez-lib-2.23 function
sdp_data_alloc_with_length for this. Im seeing nothing
still in my 1248 id.

As seen in the trace -- aid 0x0358 (unknown) is blank
or data is nothing. Do you have any idea whats the
problem? How do I solve this problem?
Thanks for your time.

Hi Marcel,
Just to add.. If I dont use 0x00 to my 1248 id, it
works. But If I put a 0x00 to the data it wont work.
So I guess it is a problem considering that the first
two bytes is the length of the id and for the first
byte not to be 0x00 I should give a data that the
length is more the 255. for the first to bytes not to
be 0x00, the lowest that i can to use is 0x01 and
0x01... this is equal to 257. Is there a way to
correct this problem?
Thanks for your time.

I might haven't fixed the parts in hcidump to deal with binary strings.
Add the 1284 ID with your tool and then run "sdptool browse --raw local"
to see what has been added to the SDP server.

Hi Arch,

last week ago or so, Collin ran into the same problem with the HID
report descriptor. It is also a binary string. With bluez-libs-2.23 you
can use sdp_data_alloc_with_length() to specify the length of the string
and then it should work fine.
