[Bluez-devel] Extracting full SDP database from device at once using DBus API

[Pierre-Yves Paulus <py@idlum.be>]

Hello,

At the moment, to perform a full extraction of the SDP database of a 
device, I first perform a call to

array{uint32} GetRemoteServiceHandles(string address, string match)

with an empty "match" string. It does connect to Public Browse Group, 
and returns handles for all the ServiceRecords. I then perform a call

array{byte} GetRemoteServiceRecord(string address, uint32 handle)

for each of these handles, and I get all the data in binary form ti 
interpret myself.


1) Is it the right way to do this, or is there a way to get that all at 
once?

2) As ServiceRecords are extracted "one at a time", is Bluez connecting 
and disconnecting to the device each time? Is there a performance 
penalty in doing so? If I understand the output of hcidump well, it does 
not close he ACL link each time, but there is a L2CAP 
connection/disconnection for each ServiceRecord.

Thanks a lot,
Best Regards

Pierre-Yves
