Cloud Update Key
To deliver the latest firmware version to your controller over the air, you’ll need to install the Cloud Update Key in the controller. All controllers shipped as of April 16, 2018, already include this key.
- The Cloud Update Key works with the ET Pro3 and LC series controllers.
- If your controller is running 7.8.2 or 8.4.2 or later, it already has the Cloud Update Key installed.
- If you are using an OptiFlow key for the OptiFlow XR or ET Pro3, you do not need a Cloud Update Key. The OptiFlow key includes this functionality.
