As far as I know, I have tried everything to make this work. The original problem was that the controllers became untethered from the Robot. We tried re-tethering them, but nothing happened. I took the robot home, and set to boot mode, then put the new firmware on it, although the Upgrade Utility said the system was up to date. Still nothing. I get the error code that says “NO VEXnet Key detected”, which I assumed meant that it wanted me to plug in the USB Key. When I did, the system begins flashing two codes simultaneously, the “Disabled” code, and the “Linking - Searching for VEXnet Mate” code. Frustrated, I took two paperclips and hit the Config keys. Miraculously, after 3-4 attempts, it did something. The controller will now, when tethered, put up the image that the is in the user guide which is what’s supposed to happen while tethering. It doesn’t, however. NOTHING HAPPENS. I can’t even drive while tethered.
Does anyone have an idea for what to try next? I have it until next Thursday, which is the deadline we set for getting it to work, then sending it back. I have no programs on it, except for the updated firmware. I’m about ready to call this a hardware issue.
