Vex IQ Not Connecting To Controller

Our robot is working, however when we are driving it stops and says “Connect Controller” and then the driving continues again. We have replaced both the brain and the controller, reinserted the radio modules, and pushed the joysticks inward. It happens very frequently and we do not know how to fix it. Can anyone be of assistance to our issue?

Thank you!

Hello Hunter,

Thank you for visiting our forum.
It sounds like one of your radios might be dropping your communication link. Have you tried running the system in tether mode with the cable?
If so, what are your results? Does the problem goes away?

If the radios are at fault, just contact our support team and they will be able to swap your radios for new ones:
