we change the batteries in our main joystick and now the robot light is blinking green. we tried to do the troubleshooting it says on the wiki but that just makes the vex net, joystick and game lights to turn red. can anyone help.
Thanks for taking the time to visit our forum.
My recommendation is to download firmware into your Microcontroller & Joystick, as both devices will only communicate if they run the same firmware version.
You can download firmware using your programming compiler of choice (easyC or ROBOTC). If you do not have programming software, you can update the firmware here: http://link.vex.com/downloads/VEXnetUpgrade
Let me know your results.
