about sdp server

[Arthur Evstifeev]

Good day. I have some questions about sdp service records. As i say in
issue (wrong issue:) ) after registering records i have done some
tests with sdp_record_matches_service_search_pattern and it returning
me that service found, but when i trying SERVICE_SEARCH_REQUEST i`m
not getting 1 of the services... Maybe this is the result of the wrong
records, then why both sdp_record_matches_service_search_pattern
telling me that services found?

i have tried 3 ways of the service records creating:
1. de_add_number(service, DE_UINT, DE_SIZE_16,
SDP_ServiceClassIDList);
de_add_number(service, DE_UUID, DE_SIZE_16, 0x112d);
de_add_number(service, DE_UUID, DE_SIZE_16, 0x1204);
2. // 0x0001
uint8_t *serviceClassIDList = de_push_sequence(service);
de_add_number(serviceClassIDList, DE_UINT, DE_SIZE_16, 0x0001);
uint8_t *serviceClasses = de_push_sequence(serviceClassIDList);
de_add_number(serviceClasses, DE_UUID, DE_SIZE_16, 0x112d);
de_add_number(serviceClasses, DE_UUID, DE_SIZE_16, 0x1204);
de_pop_sequence(serviceClassIDList, serviceClasses);
de_pop_sequence(service, serviceClassIDList);
3. seq2 = de_push_sequence(service);
de_add_number(seq2, DE_UINT, DE_SIZE_16, SDP_ServiceClassIDList);
de_add_number(seq2, DE_UUID, DE_SIZE_16, 0x111f);
de_add_number(seq2, DE_UUID, DE_SIZE_16, 0x1203);
de_pop_sequence(service, seq2);

And another question.. A didn`t saw in function
sdp_handle_service_attribute_request code that is returning requested
attributes by SERVICE_ATTRIBUTE_REQUEST it returning only bytes count,
i also see this in log files...

Thank you!

Hi Arthur

you only tried 3 different versions of encoding SDP attributes - but none of them is correct :)

the attribute ID is stored as a DE_UINT, the attribute values can be a single value or a data element sequence.

Try:

de_add_number(service, DE_UINT, DE_SIZE_16, SDP_ServiceClassIDList);
attribute = de_push_sequence(service);
{

de_add_number(service, DE_UUID, DE_SIZE_16, 0x112d);
de_add_number(service, DE_UUID, DE_SIZE_16, 0x1204);
}

de_pop_sequence(service, attribute);

that's because it's the specified behaviour. The service search pattern matches ANY UUID in the record, independent of any semantics.

that might be related to the incorrect record. Please try again with a correctly formatted one.

In general, the SDP implementation should be 100% for correct records, but it's not helping/verifying yours at the moment.

Hi Arthur,

thanks for the YouTube link, but can you tell us a bit more?

The SDP record said you're implementing Remote SIM Access Protocol with BTstack. I even made a wiki page as people started to ask for that: http://code.google.com/p/btstack/wiki/RemoteSimAccessProtocol

Does it run on the iPhone? How does one talk to the SIM card there - is this done using AT commands?
What's your plans for your project (open source it, free closed, or commerical)?

Best
Matthias

yes i have implemented rSAP on iphone. In video i tried to watch that
but i understand it not so good )) in the beginning of the video i
have called from iphone to nokia telephone to watch the phone number
of the iphone. Then i turned on the fly mode in the iphone and from
the terminal started application (gui version will be soon). Then i
connected from nokia 616 car kit to the iphone (no codes because of
the link key) and then i called from nokia 616 to the iphone and i
tried to watch that there is no sim in nokia 616 and the phone number
identical to the iphone number. :)

about this app for now, but hope to know them soon :)
