I vaguely recall mention of 7? Not sure.


Class is over and I'm still wondering why we could not fire up more than 5
bluetooth connections.  Actually, these were NXT to NXT connections.  The
RaceCar project at nxtprograms.com served as the basis for the RC Bluetooth
connections.

We tried quite a few things to get more than five students on at a time.  We
know that when one disconnects, then another can grab the available connection.
We tried using another message box, making the BT connection down the hallway
and far from the classroom, etc.

We made sure firmware versions were the same.  We mixed up the NXTs.  We made
sure all the NXTs had at least 7.5v, etc. etc.

When I get home, I'm going to write a simple counter and display program and
have it run on as many pairs of NXT (I have 24).  I'll report what I find.
