Subject: how to create bnep connection

Hello guys,
I'm really despaired because I'm trying for MONTH to create a bnep 
connection between my two Bluetooth-Dongles, but it never works =(
I only can create a connection via "rfcomm".
I really hope you can help me - I even would pay a little for that.
In addition I'm a linux-newbie, so your answers should be detailled.
I just did a new installation of openSuSE 12.1 on my both PC's. After 
that, I only installed "bluez-compat" and "bluez-hcidump". "bluez" was 
pre-installed. Now i wanted to use "pand" to connect - yeah, I know 
there is "dbus", but I'm not familiar with that, so I prefer pand.
First I tried to connect via the GUI (I use gnome), but the button for 
"Connect" is shown grayed out. After that I entered the following in the 
terminal at PC1:
# sdptool add NAP
# pand -s -r NAP -M
and at PC2:
# sdptool add NAP
# pand -c <remote-btaddress>

As seen in the GUI I had a connection for about 3 seconds, but it always 
gets terminated.
Down below you can see the hcidump messages at both PC's.
I hope you can help me.

Regards, Steffen
