In the VEXNet Upgrade Bundle page from the VexRobotics website that only one VEXNet upgrade bundle is required per robot, even for two drivers. Does that mean that if I have one controller upgraded, the second controller will also be able to control the robot? Or would another 802.11 key plus Microcontroller upgrade module also be necessary?
**Yes, only one VEXNet upgrade bundle is required per robot, even for two drivers. The second Vex Transmitter for the second Driver will Tether to the VEXnet 1.5 Upgraded Transmitter. Data from both Transmitters will be sent to the Robot over the 1 WiFi Key. **
