Hey can anyone help me out? When the drive team and I drive our robot, there is an error that says "watch dog not fed". I checked the code and everything and i don't even know if there is a watchdog in the programming. It only does it when we connect wirelessly and when we do, the error come up when I click enable. When the error comes up, it says no communication and no code and then every thing cuts in and out, the robot drives by its self, and starts shooting like crazy. Please if you can help me out I would appreciate because one it is a huge safety hazard with the robot doing its own thing and we have i district event this weekend. Thank you!

Watch dog issues are usually a result of either code that executes slowly (like intensive data tasks or infinite loops) or poor communications. If you are dropping enough packets when connected wireless it can prevent the motor watchdogs from being fed correctly -often enough. If this only happens when over wireless-not when tethered then its likely an issue with the wireless on the classmate- try different channels -there may be a lot of interference on the wireless channel you are using.
