Jon,

I was not suggesting that there was an RF issue with the Joysticks--only that a problem in that part of the chain would still allow the Bluetooth connections to report that they were operational.

Phil,

Our NXTs run the firmware supplied with the 1.46 release of RobotC. If there is a later version, I am unaware of it. We have encountered a couple of anomalies with the encoders, but this may be a "learning" issue on our part. That said, we have never encountered a problem like the ones we experienced while on the field.

There is also (what I would consider to be) a weirdness in the RobotC development environment that requires you to keep the joystick debug window open; otherwise no joystick commands reach the robot--even though the program is running. Next time we are in the lab, I think we will try closing the window while a motor is running; this might duplicate the behavior seen on the field.

Thanks for your thoughts.
