How To Escape Standalone Mode

[451stroker]

This is a follow-up question to Question 3 in my previous post. How do I escape from Standalone Mode once I have downloaded a program to the Cortex via USB? Once I download a program to the Cortex via USB, I am unable to regain control of the Cortex without using the Reconfig button and going through the pairing procedures with the joystick all over again. I have some robots in my class that are stuck in Standalone Mode.

Thanks!

See my previous answer.

RobotC is able to download code to the cortex that is always run when the cortex is turned on, this is called “stand alone” mode and is useful when using the cortex without the joystick controller. We can also download code that is intended to be run when the cortex is using the VEXnet key and connected wirelessly to the controller, these different situations are selected using the “Robot->Vex cortex communication mode” menu. Setting this to “USB Only” assumes no joystick is used, setting to either “VEXnet or USB” or “competition” will require a VEXnet key to be used with the cortex.

You have to download the RobotC program in either of the two communications modes I mentioned, that’s the only way, the cortex will then start looking for a VEXnet key and try and connect to a joystick. The actual connection (whether you use the USB A-A cable or programming kit does not matter, you can select one of those two modes and still use the USB cable directly to the cortex)
