Updating Wispr Flight Firmware
1. Download the latest Wispr Ground Control from our Downloads page.
2. Plug in a USB to USB Mini cord going from your computer/laptop (USB) to the back single port (USB Mini) on the top tier of the drone.
3. Once plugged into both, open mission planner. If you do not have mission planner, download the latest version from here : https://ardupilot.org/planner/docs/mission-planner-installation.html
Do not connect the drone to Mission Planner only open the program
Go to setup ->install firmware -> Load custom firmware.
4. The latest Wispr Flight Firmware will be included in the most current Wispr Ground Control zipped folder obtainable on the downloads page. Flight Firmware will be saved as .apj file like in the example below. Click the “Load custom firmware” button and select the .apj inside of the extracted folder. Wispr Flight Firmware will begin loading. A green progress bar will fill the status bar. Once it finishes you have now uploaded the newest WISPR Flight Firmware onto your drone.
While uploading the custom firmware, you may get a pop-up saying “Please unplug the board, press OK, and then plug your connection back into the Mission Planner”. This is normal and nothing to be alarmed about. Just follow those directions. This will not hurt the upload. (See below picture for example)
