Hi everyone,
I am using Xandros linux distribution in my via motherboard PC.

I have installed the bluez stack.
In that "hcitool scan is working. But when i try to connect with the
remote device using "rfcomm connect 0 <BDADDR> 1", it fails with
following message.
#rfcomm connect 0 00:80:25:02:00:35 1
Can't connect RFCOMM socket: Connection refused

The following is the hcidump:

# hcidump -x

Can anyone tell me why this is happening? Advanced thanks.
