Like other DJI drones, the Mini 3 Pro memorizes all of its flights. Flight logs allow you to review the evolutions of your drone in detail. You can view the route on the flight on a map, see the height, the speed, the flight mode, the number of satellites, the quality of the radio link, the movements of the joysticks, any error messages. In short, it is a black box. This storage of information is carried out locally with the DJI Fly application, but it can be sent online if you wish – and it is this manipulation that is in question here.
What's the point ?
The flight logs make it possible to understand a bizarre behavior of the device, to improve by studying the piloting. With graphical tools such as those of AirDdata, it is possible to study the discharge of batteries during flights, to visualize when warnings and error messages were displayed, etc. Or, in the event of a crash, to provide the data to DJI.
How to get flight logs?
The aim is to retrieve the files containing the flight data on a desktop computer, so that it is possible to send them to a site specialized in viewing the data therein. DJI Fly flight logs are stored in text files starting with DJIFlightRecord_
On Android: These files are located in the /Android/data/dji.go.v5/files/FlightRecord/ directory. Sometimes, depending on versions and updates, the data is in another directory, for example /DJI/dji.go.v5/FlightRecord. Sometimes somewhere else again: you have to dig a little...
On iOS, it is recommended to use Apple's Files app, On my iPhone (or on my iPad), DJI Fly, FlightRecords, and share files with AirDrop (or mail).
But with the DJI FC remote control?
The connection tools do not give access to the internal memory of the radio control, which deprives us of flight logs! Since it is not possible to install Android applications, we cannot afford the services of an automatic synchronization app like that of Airdata. It also does not allow fast loading with the QuickTransfer function.
How do I get them back anyway?
The requirement is an iOS or Android smartphone. You must have installed the DJI Fly application and logged in to your DJI account. You must check that wifi and Bluetooth are activated on the smartphone and launch DJI Fly. Do not turn on the DJI RC remote controller.
After turning on the Mini 3 Pro, the DJI Fly home screen displays a message “ Switch to QuickTransfer mode. New DJI Mini 3 Pro detected. To change ».
Touch " Change », wait for the connection to be established, then close the window with the small cross at the top right.
The data is now stored on the smartphone, all that remains is to retrieve it using one of the methods indicated in the paragraph "How to obtain the flight logs?" ".
The service Airdata supports Mini 3 Pro flight logs. Don't forget that it allows flight data to be exported as a .kml file, for example for 3D visualization with Google Earth Pro. Other online services like DJI Flight Log Viewer don't work very well with Mini 3 Pro data.
The method of retrieving flight logs on the DJI RC remote controller involves synchronizing them to DJI's servers. If you refuse to see your data go to the nebulosity of the cloud, either because you don't want anyone to have potential access to your flight data, or because you simply want to strictly respect your life private, do not perform this synchronization. You will still be able to view your flight logs in local mode, on the DJI RC remote controller.
