Updating PRISM Firmware
Ensure the aircraft and RPS are powered on with sufficient power for the duration of the update.
Connect PRISM’s onboard companion computer to a wireless network. This is done by entering the network SSID and password into the Network Access fields in PRISM menu of the Vehicle Settings, and tapping “Connect.” The SSID and the word “Connected” in green will display upon successful connection.
Select “Check for updates” under the Update Utility. The system will prompt the user to power off the EchoSky Mobile to prevent interference with the WiFi data download.
Power off the EchoSky Mobile by tapping the power button, then tapping it and holding it until the handset powers off.
Restart the EchoSky Mobile. During the rebooting process, the companion computer will download the update and cache it for transfer to PRISM. Restart the WattsQGC application and allow it to fully connect to the RPA (about 30 seconds).
Access the Aircraft Settings and PRISM menu again. Verify that the new firmware version shows in the drop-down menu under the Update Utility.
Select the new firmware version from the drop-down menu and tap on “Update,” then slide the slider to confirm. This will begin the updating process.
The update will take approximately 5 minutes to install and initiate the new firmware. During this process, it will disconnect from the EchoSky Mobile RPS. Do not disconnect the power from PRISM during the update process! Once the process is complete, the drone will restart and the vehicle will become connected again. Once the vehicle has connected, verify that the new firmware is active by checking the PRISM Version on the same menu screen.
NOTE: Updating to any other firmware that has not been tested & inspected by WATTS INNOVATIONS and specifically listed on the Watts Innovations Knowledge Base will void your warranty.
NOTE: PRISM’s autopilot software is based on Ardupilot; however, users should NOT install stock Ardupilot into PRISM. This will remove the plug-and-play functionality of PRISM and will void your warranty.
