Reading from a Bluetooth device

It all worked correctly Petter the first time. I unplugged the arduino 
to see what the range would be and now I cannot get /dev/rfcomm created 
again.

So, at what point should /dev/rfcomm0 be created?

The first time that I ran this command "bluetooth-agent --adapter hci0" 
a dialog box popped up asking me for the password. This doesn't happen 
now. Maybe the password is only required once? The returned message 
reads something like device already exists.

The next command is "sudo rfcomm connect 0&". The first time, and only 
time that any of this worked, I had /dev/rfcomm0. Now I don't.

All of this is happening under Kubuntu where I can see that hc-05 is 
paired with my laptop.

Can you think of any reason that this would only work once? Does 
something need to be reset? I wouldn't have thought so.
