Generating SDP Records - Glitches #144

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
When creating records in btstack and then viewing them with 'sdptool browse 
--tree --l2cap ....' there are some records which don't show correctly (or at 
least the same as Bluez provides).

UINTs are displayed as 'integer', not UINT8/UINT16/UINT32 as under Bluez
--
    de_add_number(sppServiceRecord, DE_UINT, DE_SIZE_16, SDP_ServiceAvailability);
    de_add_number(sppServiceRecord, DE_UINT, DE_SIZE_8, 0xFF);
--
Attribute Identifier : 0x8 - ServiceAvailability
  Integer : 0xff
--

Strings shows a list on uchars, rather than strings
--
    de_add_number(sppServiceRecord, DE_UINT, DE_SIZE_16, 0x0101);
    de_add_data(sppServiceRecord, DE_STRING, 4, (uint8_t *)"COM1");
--
Attribute Identifier : 0x101
  Data : 43 4f 4d 31 00
--

I have attached the record I expect to see/am trying to copy, generated by 
adding a single SP to hci0 in Bluez.

Cheers,
Simon.

can you also post a hex dump of the sdp record created with BTstack's SDP 
utils? also, you may tweak that manually for testing -> use hexdump and put 
into an array - I did that while debugging HID descriptors for WeBe++ before.

thanks for the BTstack output. Obviously, something is different. But what's 
the difference between both encodings of an UINT8. Can you provide both SDP 
records as hex dump for comparison?

OK, I put this one down to operator error. Looks like different flags in 
'sdptool' report the data in different ways.

Please close this bug as invalid.
Simon.

I put this down to 'operator error', it looks like sdptool reports differently 
when different flags (ie. '--raw') are used.

Please close out this bug as invalid.
