i re-downloaded the master code to the controller, and now i am able to control the robot with the usb cable connected from joystick → cortex microcontroller…
however, if i want to do wifi, the controller doesnt even light up.
In order to user the VEXnet Keys you will need power on Joystick and Cortex.
If you are having power issues on the Joystick the VEXnet keys will not connect.
You should still be able to power up your Joystick with the VEXnet Joystick Power Adapter.
All of our products have a 90-day warranty.
If this Joystick is still under warranty we may be able to replace it.
If its out of warranty you can get an RMA number and mail the unit back to us for troubleshooting (repair fee may apply).
Did you double check the way the batteries are installed in the Joystick – are they all orientated the proper direction? Do you have a voltage meter so that you can measure the combined voltage of all the batteries when they are installed in the Joystick?
