[Bluez-users] pand vs. sdpd

[aeriksson@fastmail.fm]

Hi all,

I'm having problems getting a pand network up and running.=20
The tricky thing is that I have had it working once before
so I know that the hw is ok, but now I cannot recreate the=20
setup. I've been following all the docs I could find to no=20
avail.

The situation:
I have hcid and sdpd running. I start pand with the intent=20
to connect to it from my w2k laptop. The connection fails
to establish.

Observations:
* There is no bnep0 device created regardless of pand running=20
or not. My memory is a bit shady on _when_ that device was
to be created.=20

* Running all processes under strace I notice that, when trying=20
to connect from the laptop, sdpd gets a kick, but pand does not.
sdpd says:

Having briefly looked at the pand code I got the=20
impression that sdpd should alert pand when=20
connections arrived (and pand should have created=20
bnep0 long before that??).

If this sounds at all familiar to anyone all help is
appreciated. I'm stuck now :-(

TIA,

/Anders
