Robot Code Making Programming Laptop Disconnect

[Dkt01]

Try disabling the wireless on whichever laptop you aren't currently using. For example, if you are doing a real-time deployment, only use wireless on the laptop that is executing the deployment.
This seemed to solve much of our problems, but we still lost communication occasionally.
On a similar note, we seemed to notice that we lost communication more frequently during a real-time deployment when the driver station was open. We didn't look into this much, but it seemed strange to us.

We're using both, one to host the code and the other to host the driver station.

Also, using both laptops in the exact same configuration worked fine with a different version of the robot code.

Sounds like an overly saturated CPU -- code demanding too much CPU time.

Try running the System Manager and watching the CPU utilization.

Found the problem - one single loop in periodic tasks didn't have a wait on it. Ugh. I should remember to use the CPU measurer thing (See, I don't even know its name!) more often.
