(FTC) (Rookie) Firmware updates for the current season #Hub - cwm9cwm9/TTGT-FTC-FRC GitHub Wiki

Every season you should update the software of the Control Hub, Expansion hub, and Driver Station.

With the expansion hub NOT attached to the control hub in any way, the steps are:

1. Download and run the REV Hardware Client (revrobotics.com)
2. Attach the Control Hub and/or Expansion Hub and/or the Driver Station to the the computer with a USB cable(s).
3. Click the update buttons (you may need to download the software first.)
4. Replace the Robot Control app with the latest version, understanding any Android Studio code will be lost. (You'll have to recompile and redeploy using the new year's library.)

More instructions are available on the REV Hardware Client download page and subsequent pages.
