Updating V5 Brain Firmware through a Controller in VS Code – VEX Library

You can update your V5 Brain’s firmware in VS Code by connecting with a controller that is tethered to the V5 Brain.

To update the firmware, ensure the controller is tethered to the Brain and a radio is connected to the Brain. Both devices must be powered on to connect them to VS Code.
