Updating Operating System

The Control Hub’s Operating System is field-upgradable. New updates are released to incorporate fixes, improvements, and new features as they are developed.

There are two ways you can update the Operating System. It is recommended to use the REV Hardware Client, as it will automatically notify the user if the Hub's Operating System is out of date, download the latest OS, and install the OS on the device. The second way utilizes the FIRST Robot Controller Console. For using the FIRST Robot Controller Console, you will need to download the latest Operating System.

Download the Control Hub OS Version 1.1.6

Updating the Operating System can take some time depending on the size of the update. Expect the update to take approximately 5 minutes to fully complete, and keep the Control Hub powered during this process.

The following procedure works with Control Hubs with the part number REV-31-1595. For support using the REV-31-1152 Control Hub v0, please reach out to REV support ([e-mail]).

Using the REV Hardware Client 2

Steps
Power on the Control Hub, by plugging the 12V Slim Battery (REV-31-1302) into the XT30 connector labeled “BATTERY” on the Control Hub (REV-31-1595).
The Control Hub is ready to connect with a PC when the LED turns green. Note: With Robot Controller Application versions 5.5 and below the light will blink blue every ~5 seconds. Please update to 6.0.
Plug the Control Hub into the PC using a USB-A to USB-C Cable (REV-11-1232)

Start up the REV Hardware Client 2. Once the hub is fully connected, it will show up on the front page of the UI under the Hardware Tab. Select the Control Hub.

After selecting the connected device, the Navigation Tab will pop up. Select the Update Tab on the right, highlighted by the orange box.

Once in the Update Menu, confirm the desired Control Hub OS version, then click the Install Button below.

Keep the Control Hub powered while the update is installing. The Control Hub will reboot to complete the update.

Once it reboots, you'll see a green Update Complete banner at the bottom, meaning the update was successful.

When using OS 1.1.2 or newer, the Control Hub operates by default on the 5Ghz band. You may need to update the Wi-Fi settings depending on what Driver Station device you are using.

When updating from OS 1.1.1 or earlier to OS 1.1.2 or later, the Control Hub will switch to the 5 GHz band, regardless of the previous Wi-Fi band setting. Some devices do not support 5 GHz Wi-Fi, and will not be able to connect to the Control Hub wirelessly while it is using the 5 GHz Wi-Fi band. To switch to the 2.4 GHz band without needing a computer, see the Changing Wi-Fi Band section.
