From time to time, BBQ Guru will release an update to the CyberQ Cloud's operating software called firmware. If a new firmware is released, then the next time your CyberQ Cloud turns on and connects to the internet in Infrastructure mode, it will be notified there is a firmware update. On the LCD screen of your device there will be a notification that a firmware update is available. There are two types of firmware upgrades: optional and critical updates. We always recommend upgrading to the most recent firmware version even if it is optional. Using the arrow keys on the device, you can select to install the update right away or to postpone it for a later time. If you choose to install the firmware, your CyberQ Cloud will download the new file update. Do not unplug your CyberQ Cloud in the process and do not disconnect it from its WiFi connection. After the files are downloaded, it will install the files. Once the files are installed, it will reboot with the update. You will then have the most up-to-date software on your device.
