Hi Marcel,

If I do an hciconfig -a, i get the following info:

hci0:

I don't get any errors on calling dmesg, but I have
DHCP running in eth0 , does this have any influence
on the bluetooth connection?

Now, I've managed to assign IP to bnep0 in both
machines,and when everything is stable, I can ping
from one machine to the other, but I've checked that
sometimes bnep0 gets down, I can see it with
ifconfig -a, and I can assign the IP again, but how
can I do to mantain bnep0 stable?
It is something very strange because sometimes it
works fine for five minutes, others is just a pair
of minutes, and in one of the tests it's been
working for twenty minutes!

I send you the output on hcidump -w before doing a
pair of pings.

Thank you very much!!!!

Albert
