At a glance

This page collects the calibration and firmware steps that repeat across DJI Enterprise aircraft. Each model guide covers its own batteries, props, crash and water triage. Use the table to see which procedures DJI publishes for your aircraft and where the full model detail lives.

Before you start

1. Match firmware and read the notes first

• DJI recommends keeping the aircraft, batteries and remote controller firmware up to date before each flight. If an update fails, restart the device and try again; contact DJI Support if it persists. [1][11][9]
• The aircraft, remote controller, payloads and batteries must be on compatible versions. Otherwise the aircraft cannot take off or there may be safety risks. [6][11]
• When some modules don't match the system's compatible version, DJI Pilot 2 asks for a consistent firmware update. [12][8]
• Read the current release notes, and the known-issue list where DJI publishes one, before you replace a part over a calibration or update fault. [13][14][15][16][17][18]

2. Safety

• Keep the aircraft away from people and animals during a firmware update, system calibration or parameter configuration. [12][7]
• Use trusted external devices when you exchange data over the internet or update firmware. [12]
• Don't remove accessories or power off devices during an update. [12]

3. Tools DJI mentions

IMU calibration

Compass calibration

Rules for every model

• Only calibrate when DJI Pilot 2 or the aircraft status indicators prompt you. Blinking red and yellow alternately means compass calibration is required. [7][12][10][8]
• The M30 manual also recommends calibrating before the first takeoff after long storage, after the aircraft was near strong magnets, or before a night takeoff. [3]
• Don't calibrate near magnets, parking lots, construction sites with underground reinforced concrete, or metal such as bridges, cars or scaffolding. Carry no phones or other ferromagnetic items. [3][5][12]
• If DJI Pilot 2 reports strong interference after calibration, follow the on-screen instructions. [12][7]

Procedure (M30, M350, M300)

1. Step 1

   Start

   M30 and M350: in the DJI Pilot 2 camera view, open settings, then Sensor Status, Compass, Calibrate Compass. The rear indicators turn solid yellow. M300: tap the aircraft status bar, select Calibrate and follow the prompts. [3][7][5]
2. Step 2

   Horizontal turn

   Hold the aircraft level and rotate it 360°. The M30 manual says about 1.5 m (4.92 ft) off the ground. The indicators turn solid green. [3][7]
3. Step 3

   Vertical turn

   Hold it nose-down and rotate it 360° around the center axis. [3][7][5]
4. Step 4

   Read the result

   Blinking red: calibrate again. Red and yellow alternating after calibration: strong interference, so move and retry. If the prompt comes back once the aircraft is on the ground, move to another spot and recalibrate. [3][7]

Pass values

• Compass interference under 50 after calibration, outdoors (M30, M300, M350, Matrice 4, Matrice 400). [1][4][6][9][11]
• Data for each compass is shown in the app, the heading matches the real heading, and the needle is stable (M350, M400). [6][11]

Remote-controller compass

1. Step 1

   When

   A warning prompt appears after the controller is used near electromagnetic interference. Tap it to start. [3][7][8]
2. Step 2

   Manual start

   From the controller home screen open Settings, then Compass, and follow the on-screen diagram. [3][8]
3. Step 3

   Done

   A prompt confirms success. If the compass is already fine, "Calibration Success" shows as soon as you open the view, and no calibration is needed. [3][7]

Vision system calibration

DJI Assistant 2 procedure (M30, M300, M350)

1. Step 1

   Connect

   Power on the aircraft and connect it to the PC with a USB-C cable (the M30 uses its assistant port). [3][7][5]
2. Step 2

   Launch

   Open DJI Assistant 2 (Enterprise Series), log in with a DJI account, select the aircraft model and click the calibration button. [3][7][5]
3. Step 3

   Calibrate

   M30: face each side's vision sensors at the dot pattern on the screen. M350: keep reflections off the screen and face the calibration icon to all six directions. M300: face the dotted side of the visual calibration plate to the vision system. Follow the on-screen prompts. [3][7][5]
4. Step 4

   Wait

   Don't power off or unplug the cable until the data calculation finishes. [3][7][5]

Pass check

• Vision systems in all directions are enabled with no error prompt (M350, M400). [6][11]
• Keep the sensor glass clean and free of stickers. On the Matrice 4, dirty sensor lenses make false obstacle avoidance more likely in fog or at night with bright lights. [9][21]

Gimbal & payload calibration

Center of gravity (M300, M350)

1. Step 1

   Conditions

   Windless, with a strong GNSS signal, the aircraft hovering and in visual line of sight. [7][5]
2. Step 2

   Run it

   In the app's flight controller settings, tap Center of Gravity Auto Calibration. The status indicators glow solid purple, and the app confirms when it's done. [7][5]

Thermal FFC

• Tap FFC in the thermal camera view. The view pauses for about a second and the camera clicks. [22]
• Don't run FFC continuously: DJI warns it can overheat the shutter and affect image quality. Auto FFC recalibrates at regular intervals. [22]

Zenmuse L2

1. Step 1

   IMU calibration flight

   Tap Calibrate in the IMU Calibration Status area. Fly the calibration at the start and end of a flight, with no obstacles within 30 m of the start and end points. [23]
2. Step 2

   Collect re-calibration data

   In an area larger than 200 × 200 m with a building facade, fly an Area Route of about 5 minutes with the settings DJI lists (IMU Calibration, Elevation Optimization, RGB Coloring, single return, repetitive scanning, 50% side overlap, 100 m altitude, 10 m/s). [23]
3. Step 3

   Export the file

   In DJI Terra v3.9.0 or later, run a LiDAR Point Cloud Processing task with LiDAR Calibration and export the calibration file. [23]
4. Step 4

   Load it

   Copy the file to the root of a microSD card, insert it in the L2, mount the L2 and power on. Calibration takes about 5 minutes. [23]

Gimbal mounting, dampers and lens care for each aircraft: M30, M300 / M350, Mavic 3E / M4.

RTK checks

1. Step 1

   Enable and set the service

   Before each use, check in the DJI Pilot 2 camera view RTK settings that RTK is enabled and the RTK service type is set correctly. Otherwise RTK can't be used for positioning. [3][7][5][8][10][12]
2. Step 2

   Turn it off when unused

   M30, M300, M350 and Mavic 3E: disable RTK if you aren't using it, or the aircraft can't take off without differential data. [3][7][5][8]
3. Step 3

   D-RTK 2 base

   Set up and link the station per the D-RTK 2 user guide and switch it to Broadcast mode for your aircraft. Select D-RTK 2 Mobile Station in the RTK settings and wait for satellites. [3][7][8]
4. Step 4

   Custom Network RTK

   With the controller online (Wi-Fi, or a cellular dongle on the Matrice 4 and 400), select Custom Network RTK, enter the NTRIP server details and tap Save. Keep the controller on and online. [3][7][10][12]
5. Step 5

   Confirm FIX

   The aircraft's positioning status shows FIX when it is using differential data. [3][7][12]
6. Step 6

   Mavic 3E RTK module

   Fit it to the PSDK port with the aircraft off. It is not hot-swappable. [8]

Pass values

• RTK page shows heading and positioning both fixed (M350, M400). [6][11]
• GNSS reaches Strong within one minute outdoors, and the RTK data meets the heading measurement standard (M30, Matrice 4, Matrice 400). [1][9][11]
• Satellite count: at least 7 in P-mode (M350); at least 25 in N-mode (M400). [6][11]

Firmware updates

Online with DJI Pilot 2

1. Step 1

   Prep

   Aircraft linked to the controller and the controller online for the whole update. M30, M350 and Mavic 3E: both above 25% battery. Matrice 4 and Matrice 400: DJI says fully charged. [3][7][8][27][12]
2. Step 2

   Update All

   Tap the firmware prompt on the DJI Pilot 2 home screen, then Update All. Both devices restart when done. DJI quotes about 15 minutes on the M30 and Mavic 3E, depending on the network. [3][8][12]
3. Step 3

   Battery station

   Insert the packs, power on the station and connect its USB-C port to the controller. Tap the station update prompt in Pilot 2, then Update All (about 10 minutes). Don't insert or remove batteries or unplug the cable during the update. [3][7][12]

Offline package

1. Step 1

   Download

   Get the offline firmware package from DJI's download center onto a microSD card or USB drive. [3][12][18]
2. Step 2

   Install

   In DJI Pilot 2 tap HMS, Firmware Update, Offline Update, select the package for the controller, aircraft, payload or (M30) battery station, and tap Update All. [3][7][12]

PC with DJI Assistant 2 (Enterprise Series)

1. Step 1

   One device at a time

   Connect the aircraft or the controller to the PC separately; DJI Assistant 2 can't update several devices at once. Device powered on, PC online. [3][12][8]
2. Step 2

   Update

   Log in with a DJI account, open firmware update on the left, select the version and click to update. Wait for "Update successful"; the device restarts. [3][12][8]
3. Step 3

   What's normal

   A limp gimbal, blinking status indicators and reboots are normal during an update. [12][8]
4. Step 4

   Afterward

   The controller and aircraft may disconnect after an update. Re-link them if needed. [12][10]

Mixed M300 / M350 fleets

• Follow DJI's order: remote controller, aircraft, DJI payload, battery station, then batteries. DJI warns skipping it can leave a device permanently unusable. [20]
• The DJI RC Plus must be updated before it updates a BS60 or BS65 station. [20]
• Moving an M300 to the DJI RC Plus needs a one-time DJI Assistant 2 offline update on a Windows PC. Details are in the M300 / M350 guide. [20]

Known update issues

• Matrice 4: an update can fail if the controller is more than 200 m from the aircraft. [21]
• M300: an update may fail with a PSDK payload attached; remove the payload and retry. [28]
• Mavic 3E/3T: after a consistent or complete update the status indicator can stay solid green; restart the aircraft. [29]
• If an update fails, restart the aircraft, the controller and DJI Pilot 2 or DJI Assistant 2, then retry. [27][30]

HMS, logs & linking

Health Management System (HMS)

1. Step 1

   Read the warning

   Open HMS, tap any abnormal module, then the warning, and follow DJI's help document. [6][9]
2. Step 2

   Upload the logs

   If it persists, upload the logs from Manage Logs and send DJI Support the QR code or tracking number. [9]
3. Step 3

   Export flight data

   Flight data is stored on the aircraft. Connect it to a computer by USB and export it with DJI Assistant 2 or DJI Pilot 2. [12][10]
4. Step 4

   Payload logs

   For the H30 or L2: HMS, Manage Logs, select the payload to export its log to the payload's microSD card. [22][23]

Re-link the remote controller

1. Step 1

   Start linking

   Power on both. Press C1, C2 and Record together until the controller status LED blinks blue and it beeps, or tap Link Remote Controller in DJI Pilot 2. [3][12][8]
2. Step 2

   Aircraft side

   Hold the aircraft power button for at least five seconds (M30, M350, Matrice 4, Matrice 400) or more than four seconds (Mavic 3E). M300 with a Smart Controller: press the aircraft's linking button. Keep the controller within 0.5 m. [3][7][12][8][5]
3. Step 3

   Confirm

   The controller beeps twice and its status LED turns solid green. [12][3]
4. Step 4

   Dual operator (Matrice 400)

   From the DJI Pilot 2 home screen, tap Remote Controller A/B and link each controller the same way. The first controller connected gets control of the aircraft and gimbal. [12]
