An Operating System (OS) is software that supports a computer's basic functions, such as scheduling tasks, executing applications, and controlling peripherals. This must sometimes be updated on the REV Driver Hub.

Here are two methods for updating the Driver Hub OS:

1. REV Hardware Client (RHC)
2. Software Manager on Driver Hub

For other FTC updates, click sidebar links at the right side of this page.

More info about updating the Driver Hub OS is here at REV Robotics' excellent documentation site.

1. Turn on the Driver Hub. Plug it directly into a computer running the REV Hardware Client, with a USB-C data cable.

2. Click the Driver Hub's large icon/rectangle. Under "Driver Hub Operating System", see the current/latest mismatch, if any (yellow oval, below).

Confirm the Latest Version in the drop-down menu, if any. Then click the blue rectangle, labeled "Update" when applicable. The speed of this update is improved, since you already downloaded the OS file at the start of this tutorial.

Done! The Driver Hub's OS is now updated.

The REV Driver Hub has a built-in app called the Software Manager, which can automatically update the Driver Hub OS (and other FTC-related software). It requires only an internet connection.

1. Close all apps, and open the Driver Hub's Wi-Fi menu (in Settings, or swipe down twice from top of home screen). Temporarily connect the Driver Hub to the internet via Wi-Fi.

2. Open the Software Manager app at the Driver Hub home screen (left image, below).

3. The Software Manager will automatically check for any updates needed, and display the results (right image, above). Touch the grey button to perform the updates, including the Driver Hub Operating System (OS) if needed.

The REV Robotics website does not provide a downloadable OS file for the Driver Hub, as it does for the Control Hub.

4. When all is complete, "Forget" the Wi-Fi network used for internet access. Now the Driver Hub is ready for regular FTC use.
