Has anyone else had problems with the top light on the VEX IQ controller holding a steady red? I have tried turning it off/on, downloading firmware, and several other things but can't seem to solve the problem. The controller will drive the robot while plugged in with the tether cable but when disconnected, it won't drive anymore. Often the message on the brain says the remote radio needs to be updated but I don't know any way to do that other than updating the firmware and that hasn't taken care of the problem.
