The DJI Assistant 2 software contains extras settings and utilities for all DJI equipment such as drones, gimbals and cameras.

With the DJI Assistant 2 Mavic, you have options to upload  flight data, black box information, calibrate your vision sensors and upgrade your firmware. There is also a DJI Assistant 2 Simulator for testing flight parameters and practice flying your Mavic Pro.

The DJI Assistant 2 download and install only takes a few minutes and is available for Windows and Mac computers.

This post contains all the essential information and more on the DJI Assistant 2 app for the Mavic quadcopter. Now, if you have a Phantom 4 or DJI Spark, the DJI Assistant 2 is the same version. Therefore the below Assistant 2 settings and utilities will be very similar.

Now, the DJI Assistant software is for all DJI equipment.  All DJI equipment have a micro USB port.  With the DJI Assistant software installed on your computer, you then connect your DJI device. The DJI Assistant will recognize the device whether it is a DJI Goggles, Mavic, Spark, Phantom, M600, Osmo, Zenmuse or Lightbridge flight  controllers etc.

For most DJI equipment, the DJI Assistant will only allow you to update the firmware.  It is different for their quadcopters.

Now, with older versions of the DJI Assistant 2, it was very easy to modify your Mavic Pro quadcopter to make changes to flight parameters and other features.  We will look at these extra settings and how you can still modify your Mavic Pro using DJI Assistant software.

DJI drone are really like flying computers with top cameras. When troubleshooting a computer and likewise with the Mavic Pro, doing a firmware update or restoring to the factory default will fix many issues.

Calibration is also a vital step in trying to fix flight issues.  The DJI Assistant 2 contains the vision sensor calibration utility which you are read more on below.

You may also see an older Mavic firmware version.  You may need to downgrade to an older version if you installed the latest firmware and it contained a bug which caused problems with your Mavic Pro quadcopter or remote controller.  You would then downgrade your Mavic Pro firmware.

Update Mavic Pro Firmware Using DJI Assistant 2

Here is the instructions on how to use the DJI Assistant 2 to update the firmware for the Mavic Pro quadcopter and remote controller. Both can be done at the same time.

  1. With the remote controller and the Mavic powered off, connect the RC to your computer through the charging port using a micro USB cable
  2. Power on the Mavic Pro RC and Mavic Pro quadcopter and make sure both are connected
  3. Open the DJI Assistant 2 software and login to your DJI account
  4. Select the “Mavic Pro” icon and click on the “Firmware Updates” on the left panel

DJI Assistant 2 Data Upload

The Data Upload section allows you to upload information from the Mavic Pro to your local computer.  You can upload aerial videos, photos and flight log data.  You can choose where you want to save the file to. The file been saved will have a .dat file extension.  The file name will look similar to “DJI_ASSISTANT_EXPORT_FILE_2017-10-16_14-15-30.DAT”. My last upload was over 1.06 GB in size as I uploaded all files.  So this can take quite a few minutes to upload.

When you first open the Mavic Pro Data Upload option, it states in the text pop up box that you will be uploading to the DJI Server.  However, I actually only uploaded the data to my laptop.   Now, you need to click on confirm before you can upload to your computer. Please read the information in the pop up box before confirming.

Here is the full instructions on using the DJI Assistant data upload.

  • Click on ‘Data Upload’ from the left hand side
  • Read the information and click on ‘Confirm’
  • The Data Upload utility reads and lists the files which will be uploaded by the Mavic Pro Assistant software
  • All files are un-selected. You can select all or choose which files you want to upload.
  • Click on ‘Safe To Local’ –  This allows you to save the Mavic Pro data onto your local computer. Now, if this fails, then just out out of the Data Upload and back in and it should work the second time
  • As it is uploading the files to your local computer is is also compressing the files
  • Click on Complete at the end. All the individual files are now saved as one compressed DAT file.

So we basically have made a backup of the Mavic Pro quadcopter to our local computer.

DJI Assistant 2 Flight Data

This brings you into an area where you can view the Flight Data records.  This section is for checking and analyzing flight data on the Mavic Pro performance and also for diagnosis.  The data is stored in the SD card in the Resource Manager.

When you first open the Flight Data, a dialog box will appear with the following message;

“Enter the Flight Record Page. Click the SD Card icon to view flight records. Some functions maybe temporarily unavailable. Restart Aircraft to restore”

Press Confirm.

Click on Open Data Viewer and browse to the data on your SD Card.

To find the Flight Records on your Smartphone, do the following;

Connect your cellphone to your computer.  If you have an Android phone, then the cellphone shows up as a drive on your computer.  It is very similar for iPhones also. Next, navigate through the folders and find the flight record data in the DJI -> dji.go.v4 -> FlightRecord -> MCDatFlightRecords folder.

The DJI Assistant 2 Mavic Flights Records have a .dat file extension such as 17-08-05-11-10-11_FLY044.DAT.

Some of the data which you can view is as follows;

  • Longtitude
  • Latitude
  • Airpressure Altitude
  • Acc X, Y, Z  (Accelerometer)
  • Gyro X, Y, Z (Gyroscope)
  • Velocity North, East, Down, Valid

DJI Assistant 2 WiFi Settings

When you click on the WiFi Settings in the DJI Assistant 2, you will be brought to the settings page.

The DJI Assistant 2 software will pull the WiFi SSID and Password from your Mavic Pro as you can see in the below image.  I have removed some characters from my password in the below image.

Now, for the DJI Assistant 2 to recognize your Mavic WiFi SSID and password, you first need to configure and add the Mavic WiFi in your laptop network settings.

You computers WiFi will detect the Mavic WiFi so you should only need to put in your password.  To find the SSID and password on your Mavic, check on one of the front arms.  You can also find the SSID and password by removing the battery from your Mavic.

There is nothing else to configure in the DJI Assistant 2 WiFi Setting. If you have many questions regarding your Mavic, then you can find many Mavic FAQ answered here.

Modifying Mavic Pro With DJI Assistant 2

DJI Assistant 2 Software Older Version v1.1.2 to Modify Mavic

Now with the latest version v1.1.6 of the DJI Assistant, you are not able to see the extra setting to modify many of the Mavic flight settings and parameters.  With DJI Assistant 2 version v1.1.2, you could make many changes such as the below and many more.

  • Height Limit Removal
  • NFZ Removal
  • Wind Warning Removal
  • Faster RTF (Return To Home) Mode

If you have installed the v1.1.6 of the DJI Assistant 2, well you can’t have v1.1.2 installed at the same time. For example, there is no option to install the DJI Assistant to a different location in your hard drive.

So you have to uninstall the newer version and install the older v1.1.2 version. Or, if you have a 2nd computer you could install v1.1.2 on it, then attach your Mavic.  With v1.1.2, you still need to make a small configuration change in the main.js in the DJI Product > DJI Assistant 2, App Files folder. The instructions are in the below video.

You can find and download the older DJI Assistant version v1.1.2 here.  Look below the video and  you will see the links. The .exe file will be for Windows computers and the .pkg will be to install the DJI Assistant on Macs.

In the below DJI Assistant 2 video, it shows you how to configure the Assistant 2 software to give you the extra Dev-tools settings and also how to modify your Mavic Pro.

Note: Please be careful making modification to your Mavic Pro.  If you are unsure on what you are changing, then do your research, post a question on the DJI forum or even write an email to DJI Support.  You definitely don’t want to make a change that would make your Mavic Pro crash.  No one wants that.

If you are into programming, then if you want to make changes to the Mavic pro or create new applications then you should sign up and use the DJI SDK developer tools.

Ok. Watch the below video and follow the instructions to modify your Mavic Pro.
