I appreciate the heads up.

In regards to the type of communication, I'm trying = to create a BT serial connection.  The device I'm attempting to = connect to is actually a weight scale (medical device).  It = doesn't support any other services.  I probably need to add that I = changed rfcomm.conf to listen, bind, and connect for rfcomm0.  = Note: The last time I used linux was in college and it was only to = compile my assignments, so I'm not savvy.

If you are at all familiar with Windows XP, I can use = Hyperterminal to communicate with the meter simply by typing commands = in the terminal area but for this to work I have to assign a port to = the BT adapter.

Thanks,
Robert

Hi Robert,

please stop using HTML emails and especially don't = use colors. The good

I think you made a big mistake in understanding how = Bluetooth and Linux
are working. Describe what kind of communication you = try to achieve and
then we might be able to help you.
