Updating Firmware
There are two boards within the Control Hub: an Expansion Hub and an Android controller. The Expansion Hub board built into the Control Hub, facilitates a line of communication between the built in Robot Controller and the motors, servos, and sensors. In order to improve the quality of the Hubs, REV Robotics will release firmware updates for the Expansion Hub. When a firmware release occurs, both Control Hub and Expansion Hub users will need to update their Expansion Hub firmware to the newest version.
There are two ways to update the Expansion Hub Firmware. It is recommended to use the REV Hardware Client as it will automatically notify the user if the Hub's firmware is out of date, download the latest firmware, and install on the device. The second set of steps utilizes the FIRST Robot Controller Console.
To use the FIRST Robot Controller Console, the Manage interface is needed to upload the firmware file to the Control Hub. You can then use a Driver Station that is connected to the Control Hub to initiate the firmware update. You can download the latest firmware below.
In order to use the REV Hardware Client for firmware updates, the Robot Controller Application must first be updated to version 5.5. After updating the application you may need to close out of the REV Hardware Client in order for the firmware update to be available.

Power on the Control Hub, by plugging the 12V Slim Battery (REV-31-1302) into the XT30 connector labeled “BATTERY” on the Control Hub. |  |
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. |  |

Updating the Expansion Hub Firmware |
1. Connect the computer via Wi-Fi to the Control Hub or RC phone. In the Chrome browser, open the Manage interface.
|
2. Click on the Manage tab, scroll down to Update REV Hub Firmware.
 See if the grey box (see green arrow, above) offers the latest firmware version, included or bundled with the RC app. |
3. If not, click the “Select Firmware…” box. Navigate to the desired firmware file stored on the computer, and select it. As part of the update process, that selected firmware file will be stored on the Control Hub or RC phone, in a subfolder called FIRST/updates/Expansion Hub Firmware. |
4. Now click the box called “Update to…” or “Update using…” (see green arrow, above).  |
5. At the confirmation prompt, click the blue box “Update Hub Firmware”. Wait for the process to finish; do not unplug the Hub or restart the robot. |
