Question Communication error
When we first set up the control system (we are a veteran team and are using our old board right now,) we noticed the communications glitched a couple times. The communications would stop and resume as before. We ignored it, thinking it is a dashboard problem (and decided to investigate later if I have time.)

Now, when we powered up our robot for the first time today (it previously ran fine,) we started to move, then it happened again. This time, we noticed the status light was off and the robot's communication did not resume.

We then rebooted it, and I noticed the blinking lights on the bridge (cRio's radio) were not quite regular, they paused once in a while (it appeared randomly, every couple seconds.) I unplugged the status light for this, so it couldn't influence my perception of its blinking.

We are using Java (already using our own code for a four-CIM drivetrain.) (Hmm, I just thought about power consumption, but we were only using about 30% input on the joysticks, and yesterday we were going full out.)

What is causing these problems? We don't want to drive again until we know what's happening.

Thank you,
team 957's programmer.
