read the manpage or use "sdptool -h" ;)

	sdptool search --bdaddr <bdaddr> --tree 0x5555

Must be something vendor specific. Please show us the output.

I bet that 0x5555 refers to RFCOMM channel 17,18 or both ;-)

what is on RFCOMM channel 17 and 18? On channel 14 we have the Nokia PC
Suite FBUS protocol for Bluetooth.

My Nokia 6310 has a UUID128 that starts with 0x5555

	Sequence
	        Attribute 0x0000 - Service record handle
	                UINT32 0x00010008
	        Attribute 0x0001 - Service class ID list
	                Sequence
	                        UUID128 00005555-0000-1000-8000-0002ee000001
	        Attribute 0x0300
	                UINT16 0x005f

Maybe this is only checked to activate some Nokia<->Nokia special
features. For example remote PIN code or name change.

Regards

Marcel

tried that already, but with no luck. From hcidump, I see that this is a 128bit
uuid - how can I specify this as an argument??

I think sdptool isn't capable of it. Write your own code or use sdptest
from libs2/test CVS repository.

	sdptest records <bdaddr>

Hi Marcel,

the Nokia 6310 has a serial port running on RFCOMM 17 and/or 18 which
allows you to connect and fire AT commands, without having a pairing.

See:
http://www.betaversion.net/btdsd/db/Nokia6310i.txt
http://www.saftware.de/bluetooth/btxml.c

are you sure? Using attest with my Nokia 6310 on channel 17 or 18, I get
a connection refused message.

Hi Collin,

> yes I'm sure - a friend of me test this very well (he wrote btxml.c).
> There for I thought 0x5555 would be the "key" to these two channels.

then there is a difference between 6310 and 6310i, because the Nokia
6310 have no service on RFCOMM channel 17 and 18. Phonebook reading
without pairing goes through OBEX.

The btxml.c is much too complex for this and there is no need to go
through a TTY device for it. I can be done directly through a socket.
Maybe he should look at attest.c for an example.

I need the output of "sdptest records <bdaddr-6310i>" to see if this
model has more hidden SDP records.

Regards

Marcel

you can found it under libs2/test/sdptest.c in CVS.
