Subject: [Bluez-users] Can't connect RFCOMM socket

Hi

First of all thanks again for your time, maybe this is another proof of
my lack of basic knowledge, but I've trying a lot and can't get ride of
this error (I know this error is in many mails arround the list, but I
have not find the particular remedy for mine)

When I try:

rfcomm connect rfcomm0 00:10:60:A5:8F:8A 5

I get:

Can't connect RFCOMM socket: Connection refused
___________

modules l2cap, rfcomm are already loaded.
I have not paired both devices before, I only worry about this when the
pop-up PIN helper window claims for the PIN... but this time it doesn't
happen ?how should I pair before?

Regards,


This is the dump for the device running rfcomm connect:

the dump shows that there is no service running on RFCOMM channel on the
other side.
