What is DJI Assistant 2

DJI Assistant 2 is free maintenance software for Mavic series provided by DJI. Works with Windows PC or Mac. What you can do with this software depends on the model of the drone you are connecting. In the case of DJI Mavic Mini, three functions can be used: firmware update, retrieval of a log file for investigation (.DAT file), and a simple flight simulator.

DJI Assistant 2 can be obtained from the DJI download page . There are three types of software: "DJI Assistant 2", "DJI Assistant 2 For Mavic" and "DJI Assistant 2 For Phantom".

Use Mavic simulator with DJI Assistant 2

DJI Assistant 2 has a built-in drone simulator. When you connect a DJI drone to a computer, you can fly it on the computer screen.

First, start DJI Assistant 2 on your computer.
Next, connect the controller and the smartphone, and start the

(DJI Fly) app. Insert a USB cable into the drone to connect to a computer.
DJI instructs you to remove all drone propellers in case something goes wrong, but if the simulator starts up correctly, the motor will not spin during the simulation.
Turn on the controller and drone, and connect the drone to the computer with the USB cable.
When connected to a computer correctly, "Connecting to DJI Assistant 2" is displayed on the

(DJI Fly) app screen.

In DJI Assistant 2, select "Simulator" from the menu on the left. Then it will be like this screen, so click "Open".

Then this screen will appear. You can specify latitude, longitude and wind speed to simulate. The north-south wind speed is specified by the "North component", the east-west wind speed is specified by the "East component", and the vertical wind speed is specified by the "Downward component".
Click "Start Simulating" to start the simulation.

A new window will open and the drone will be displayed. The

(DJI Fly) app switches to the camera view screen. You can operate the simulator by operating the controller in the same way as flying a real machine.
Click on this screen and move the mouse on the computer to move the viewpoint.

If you right-click on the screen where the drone is displayed, such a setting screen will be displayed.
If you check the "show trace", the flight path will be displayed on the simulation screen.
If you check "save trace to file", the log file that records the flight trajectory will be saved in text format. A folder named [TRACE_FILES]-[(Date and time of execution)] is created under the folder indicated by "save path", and the log is saved under the name "trace.txt".

This is the screen showing the flight path.
