Downloading to the controller

Today I got our new programming hardware kit and I plugged it into the controller with it connected to the cortex through vexnet keys. I clicked download on the computer and it said it couldn’t connect to any devices. The communication mode is set to vexnet. Both have been updated and the keys have been to. If any one can help me with this that would great!

Okay, we had this issue too. Have you checked which communication port you are using? Sometimes it will change when you are downloading code, or just using RobotC. To check which one, go to view, then select communication port and a window should pop up. Make sure you have selected the option that says Vex Robotics

Thanks that worked
