Hello, my team and i are creating a robot using robotC and i have seen that the vex supports the 802.11g which basically allows you to have access using wireless. I would like to have the pc and the vex communicate. I have searched around the internet but i haven't found anything that might help me... How is it possible to establish such a connection?

There is a guide on the ROBOTC wiki specifically for setting up the VEXNet system that you may want to take a look at (you can find it here).

Basically, you will set up the pair the Cortex and the Joystick Controller, change the settings in ROBOTC to enable VEXNet debugging, send the changes to the Cortex, and start using the VEXNet controller. If you run into any issues at all, please let us know what the issue is and what step you are on and we'll be more than happy to help.

hi john -
i am trying to setup a vexnet link between the cortex and the joystick.
i have got the latest firmware installed on both devices, and have followed the instructions in the setup guide.
usb A2A cable is connecting them, power on the cortex.
the vexnet light comes on green on the joystick, but does not turn on for the cortex.
spinning my wheels at this point.
