[Bluez-users] pand connection to XP SP2 fails

[Bluez-users] pand connection to XP SP2 fails

[Erwin Authried]

I want to establish a pand connection to XP/SP2 with a MSI-6967 dongle.
I have installed the MSI driver for WinXP with SP2. The client is a
Laptop with a CBT100C card, Linux 2.4.22-mh7, bluez-libs+utils 2.12.
When I try to connect to the XP box with 
  pand --role PANU -c <ADR>
Windows is asking for the Pin. After entering the correct pin, I'm
always getting the following pand error:

...
pand[15249]: Connecting to <ADR>
hcid[15183]: link_key_request (sba=..., dab=...)
pand[15249]: Connect to <ADR> failed. Protocol error(71)

I'm able to connect to a PC running Bluez with the same setup.

-Erwin

show us the output of "hcidump -X" (as root) while your are connecting.

Hi Erwin,

The linux box is asking for a connection but the windows box respondes
with 0x0001 (Operation Failed: Invalid Destination Service UUID)
http://grouper.ieee.org/groups/802/15/Bluetooth/BNEP.pdf (page 22)

So I guess the windows bluetooth stack doesn't provide this service.
Discover the services it provides with this command:

hcitool info <bdaddr>


Best regards,
Sebastian

Thanks a lot, I found out now that XP SP2 is obviously always configured
as PANU, I didn't find any way to change that. Maybe a different driver
would help to be able to configure it as NAP, I don't know.

Erwin

Look what MS stack knows:

http://qualweb.bluetooth.org/Template2.cfm?LinkQualified=3DQualifiedProduct=
s&Details=3DYes&ProductID=3D956

It should work with our pand

so doing a PANU (Linux) <-> PANU (XP SP2) connection works?

Hello Marcel,

yes, this works fine (with pand --service PANU ...).

Hi Erwin,

> yes, this works fine (with pand --service PANU ...).

please do a "sdptool browse|search ..." with the --tree option. May we
can get the service from the SDP record and use a good default. Does a
simple "pand --connect ..." without any extra options work for you?

Regards

Marcel

this is the output of "sdptool browse --tree <adr>" from XP home/SP2.

a simple "pand --connect ..." doesn't work, it results in the 
"Protocol error(71)" from pand. It seems that pand defaults to remote
service "NAP", I wonder if there is (or should be) some kind of fallback
mechanism  that tries GN and PANU as well.

there is no need for a fallback. We should simply use the information
from the SDP search if nothing else is specified on the command line.
Will anyone volunteer to look at this and create a patch?

Regards

Marcel
