[Bluez-users] Question to using sdptool

[Bluez-users] Question to using sdptool

[andreas.knuth]

Hi,

I am trying to generate some testcases for testing the BT-solution in o=
ur
products. Therefore some small questions.

I am using two BT-dongles on one host.
At moment when I'm execute "sdptool add <service>" or "sdptool  -i hci1=
 add
<service>" both hcix gets the service.
Question:
Does provide bluez more then one sdp-daemon - especially to each local
BT-address one dedicated daemon?
Or is it possible to have two separated sdp-data bases - one for each l=
ocal
address?


One Question to the options on the command line listed via "sdptool".
When I try to use the option "--source" I get the error   >> unrecogniz=
ed
option '--source'  <<. I am remember me that this option was implemente=
d in
the past.
Now i found the working option -i for specifying the the outgoing
connection for sdptool requests :-) Does someone plan to update the hel=
p
description?

If the option -i for using with sdptool is correct : when I execute
"sdptool -i hci1 browse" then bluez is doing on hci0 an inquiring and w=
ith
the results on hci1 the sdp-requests. Is this process as expected?

One wish to the bluez developer:
The old link-key file (etc/bluetooth/link_key) contained also the time
(+date) of generating the corresponding key. In the new one
(/var/lib/bluetooth/.../linkkeys) the time (+date)is missing.
It was a helpful feature for testing. It is possible to implement this
again?

Thanx

Mit freundlichen Gr=FC=DFen / kind regards

It doesn't really make sense to have one sdpd per device. Services
aren't really bound to a device, rather the machine to which the device
is attached.

Fixed in CVS.

Hmmm. It seems there is no way to pass the interface to
sdp_general_inquiry(). Perhaps it is best to add a new function,
sdp_directed_general_inquiry()? Marcel what do you think?

this depends on it. You can bound a service to a specific and device and
in this case also the SDP records should bound to a specific address.
However I don't have really time to look into it at the moment.

If only sdptool uses these function, we can change it or fix sdptool to
use hci_inquiry and sdp_* explicitly.

I left it out, because I don't saw any reason for that. However I have
plans for a "last seen" file.
