as I said, I have two gentoo-PCs with a Bluetooth3.0-Dongle at each PC.
Now I tried to use the bluetooth-test-network to connect:
But connection was refused and I don't know how to fix it. Down below 
you find the
# bluez-test-network
# monitor-bluetooth
and
# hcidump -i hci0
-messages of both PCs. On top of that, there are different error 
messages at both PCs!

Hope you can help me in this case.

Regards,
Steffen
