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.

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 Control Console, you will need to download the latest Operating System.
Download the Control Hub OS Version 1.1.4
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 (support@revrobotics.com).
Startup the REV Hardware Client. 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 Hardware the Update tab will pop up. Under Control Hub Operating System select Download.
Once the OS has downloaded, select Update.
Keep the Control Hub powered while the upload finishes.
A successful upload will be denoted by the "Update Verification Succeeded" message highlighted in the image below. Once the upload is successful the install will begin.
Keep the Control Hub powered while the update is installed. The Control Hub will reboot to complete the update.
When the OS update has completed a status message "Operating System update complete." The status for the Control Hub Operation System will also change to "Up-to-Date."
When using OS 1.1.2 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.
