Why is Litchi not connecting to my DJI drone?

Please refer to the General tab section “Connecting Litchi to your drone”.

Why is Litchi not connecting to my Phantom 2 Vision/Phantom 2 Vision ?

When starting the app for the first time, you will need to be connected to Internet in order to validate the app with DJI servers.Some Internet connections may have troubles connecting to DJI servers, in such a case make sure to try a different Internet connection.

. I purchased the app on one device, can I install it on other devices?

You can install the app on as many devices as you want as long as they use the same platform and the same “main” account (Google, Apple or Amazon) that was used for the original purchase. If you wish to use Litchi on two or more platforms you will need to purchase it on each one.

. I won’t have Internet access where I want to fly, will I still be able to see the maps?

If you cache the maps prior to the flight, you will be able to see them even when offline. To cache maps while connected to Internet, drag the map around where you are planning to fly, zoom in and zoom out. You can exit Litchi in between but avoid restarting the mobile device as it may clear the cache.

Autonomous flights (Waypoint, Orbit, Follow, etc) fail to start, why?

The flight mode should be P-mode (F for older drones) in order for the aircraft to perform autonomous flights. If the problem persists, double check that you are using the latest supported firmware.

My Waypoint/Follow/Orbit flights fail to start, why?

Double check that you are using the latest supported firmware.

How to regain control of my aircraft during an autonomous flight when using a remote controller?

Change the flight mode to Sport (P for older drones). The aircraft will then stop the autonomous flight and you will regain control instantly.

How to regain control of my aircraft during an autonomous flight?

Flip the remote controller mode switch from the top position to the middle position and then back to top position straight away. The aircraft will then stop the autonomous flight and you will regain control instantly.

Will the aircraft avoid obstacles if there are any?

For the Mavic/Phantom 4/Inspire 2/Spark obstacle avoidance will work when it is available and enabled. For all other aircrafts, obstacles will not be avoided.

Which firmware version do I need to use Litchi?

The latest public firmware.

Is my Android device supported by Litchi?

As a general rule, Litchi supports most mid to high-end Android devices. There are many Android devices and versions out there, and even two similar devices can yield very different results, for this reason there is no list of supported devices.
The best way to find out if your device is supported by Litchi is to purchase the application and give it a try.

Is there an iOS version?

We have no iOS plans for the P2 vision series.

What is the difference between Litchi for Android and Litchi for iOS?

Litchi Magic Leash is currently only supported on Android. Litchi Vue streaming and in-app Pano stitching are currently only supported on iOS.

I purchased the app on one device, can I install it on other devices?

You can install the app on as many devices as you want as long as they use the same google account that was used for the original purchase.

Aircraft

Aircraft head tracking

In Joystick mode, rotating your head left/right is similar to using the left joystick’s left/right axis (mode 2). As an example, the more you rotate your head to the left, the faster the aircraft will rotate to the left.
The zero point, at which the aircraft will not rotate, is set when VR mode starts using the current mobile device orientation at that time.

Android

For remote controllers with a USB connection (Mavic, Phantom 3 Adv/Pro, Phantom 4, Inspire), follow these steps:

Auto pano

Auto Pano uses preset parameters to shoot a 360° spherical panorama.
In addition, Litchi will use optimized camera settings and panorama settings to improve the chances of a successful stitch in Litchi’s Panorama Database (iOS only).
Info If you use a camera which has variable focus, make sure to set the focus before starting the Auto Pano.

Bluetooth controllers

Litchi allows you to control Wi-Fi based drones (Spark, Phantom 3 Standard, Mavic Air/Pro) with a bluetooth controller when no DJI remote controller is connected.
If you are looking for a compatible bluetooth controller, we recommend the Mad Catz CTRL i for iOS.
Litchi will automatically recognize and accept input from a bluetooth controller after it is paired with your mobile device.

Camera

Camera focus

For cameras with adjustable focus, the camera focus mode can be changed in the camera settings. Available modes are Auto, AFC and Manual.
To set the focus on a specific location, make sure you are in Auto or AFC focus mode then tap anywhere on the video preview to trigger autofocus at that location.
To set the focus to Infinity (everything in focus)

, switch to Manual focus mode then tap on the Infinity (∞) button. Alternatively you can use the custom function “Focus to Infinity”. Before using Infinity focus for the first time, it is recommended to calibrate the lens. Tap on “Calibrate Lens” in the camera settings then follow the steps on-screen.

Camera settings

General camera settings as well as shooting modes (Single/HDR/Burst/AEB/Interval) can be adjusted after a tap on the camera settings icon under the shutter/record button.
An exposure info panel is also shown at the top of the video screen when connected to the aircraft.
To set the ISO/Shutter Speed/Aperture/Exposure Compensation, tap on the Camera Settings button, then “Exposure Settings”.

Camera zoom

Optical zoom: For cameras which support optical zoom but cannot be adjusted using the RC’s right wheel: hold the RC’s C2 button and use the left RC wheel to adjust the focal length.
Custom Function:

Digital elevation model files

Elevation Data can be provided using a Digital Elevation Model (DEM) file.
To import a DEM, go to “Missions” then “Import DEM”, then select the DEM file on your computer. Mission Hub supports Esri ASCII Grid format (.asc files)

Drawing tool

The drawing tool allows you to quickly setup a waypoints mission, simply draw the path you want the aircraft to follow.
To enter the drawing mode, tap the pencil icon located in the top right corner of the map. Then, draw the mission path on the map.
When you are done, lift your finger from the screen and a Batch waypoint settings window will appear, use it to set global settings for the waypoints that will be created from the drawn path.
In this window, you will find an additional setting, the “Waypoint Spacing” which is the minimum distance between the waypoints that will form the drawn path.

Elevation data

In order to use the “Above Ground” option to set altitudes, Mission Hub needs to know the ground elevation. There are two possible sources for Elevation Data.

Exposure metering

By default exposure metering is in Average mode. If your camera supports adjustable focus, you can set the exposure metering to Spot mode by following these steps:

• Do a long press on the green square icon at the top left of the video preview to switch to Metering mode.
• Tap anywhere on the video preview to set Spot metering at that location.

To go back to Average metering mode, tap again on the Spot metering icon and the icon will disappear.

Focus

Focus allows you to easily keep a subject (Point of Interest or Mobile Device) in the video frame while flying the aircraft manually.
The aircraft rotation (yaw) and gimbal pitch angle are controlled by Litchi as well as the gimbal yaw for Inspire 1-2.
Focus is compatible with Litchi Magic Leash (Android only), making it possible to focus on an external mobile device.
Enter the Focus mode by pressing the Flight Mode icon at the top left of the Litchi screen. Select “Focus”.

Follow

Follow causes the aircraft to follow the movements a subject.
The subject is usually the mobile device that is connected to the drone but it can also follow a pin on a map.
The maximum aircraft speed in this mode is 4.2m/s (no wind).

Warning It is advisable to only use the Follow feature in wide open areas.

Enter the Follow mode by pressing the Flight Mode icon at the top left of the Litchi screen. Select “Follow”. Press the Follow Settings icon on the left side of the screen.

Follow settings

For Follow to work, the app needs to know the position of the subject in relation to the aircraft. The easiest way to set these relative values is to fly the aircraft at the relative position the aircraft should be in when the subject begins to move, and press the “Set from Aircraft Position.”
All settings except “Altitude Reference” can be altered in real-time.

General

Gimbal roll adjustment

To adjust the gimbal’s roll angle, hold the RC’s C2 button and use the right RC wheel.

Ground station / waypoints

Litchi’s Ground Station mode allows you to setup waypoint missions.
Place multiple waypoints on a map however far you want and the aircraft will fly from waypoint to waypoint and complete the mission even if the signal is lost.
On Android, to enter the Ground Station, press the Flight Mode icon at the top left of the Litchi screen. Select “GS”. You can then start editing missions.

Litchi vue streaming

Platforms Litchi Vue is only available on iOS at this time.

Litchi Vue allows streaming the drone video from the pilot’s mobile device to a second mobile device using a Wi-Fi connection. This feature has a trial version that lets you stream for up to 20 minutes, and can be purchased to unlock unlimited streaming.

The following video explains how to use Litchi Vue:

Warning

Bluetooth must be turned off on at least one of the 2 devices before using Litchi Vue.

Follow these steps to setup Litchi Vue:

Loading / saving a mission

Missions can be planned anywhere, you do not need to be connected to the aircraft in order to plan a mission.
To save a mission, tap the save button in the left button bar. Enter a filename, click Ok and the mission will then be saved in the “LitchiApp/missions” (“missions” on iOS) folder located in the mobile device’s internal storage.
To load a mission, tap the load button in the left button bar, select the mission then click load.
When logged in to your Litchi account, missions will be synced automatically across all of your devices as well as on the Mission Hub.
By default, missions sync’ed in your account will be private and not visible to anyone unless you set them to public in the Mission Hub.

Mobile device camera

For remote controllers with C1/C2 custom buttons (all aircrafts except P3 Standard), you can bind the custom function “Toggle Mobile Device Camera (VR)” to either C1 or C2.
This allows you to switch between your drone’s camera view and your mobile device’s camera view, making it very easy to keep track of your surroundings with the goggles on.

Online elevation

Orbit

Orbit causes the aircraft to circle around a point of interest while optionally having the gimbal keeping focus on it.
The orbit parameters (radius, altitude, speed) can be altered in real-time.
Enter the Orbit mode by pressing the Flight Mode icon at the top left of the Litchi screen. Select “Orbit”.

Orbit settings

To bring up the Orbit settings window, place a point of interest marker on the map, then tap on it.

Panorama

Panorama database (ios only)

The Panorama Database lets you stitch, view and share the panoramas you have shot all within Litchi.
The Panorama Database is not automatically backed up or synced, as such be aware that uninstalling Litchi will also permanently delete the Panorama Database.
After selecting a panorama in the database, select the desired stitching quality and tap on “Create Panorama” to stitch it within Litchi.

Warning Avoid stitching a panorama while the drone is in the air as the stitching process can take a while and uses a lot of resources.

There are 3 available quality settings for stitching:

• Low: Uses the preview images automatically downloaded by Litchi after a panorama is shot. Can be done without downloading the high quality images from the drone but produces a lower quality panorama.
• Medium: Requires downloading the high quality images from the drone to produce a higher quality panorama. Up to 65 megapixels on iPhone and up to 100 megapixels on iPad Pro.
• High: Requires downloading the high quality images from the drone to produce an even higher quality panorama. Up to 130 megapixels on iPhone and up to 220 megapixels on iPad Pro.

Warning

Some older devices may not have the required resources to successfully stitch a panorama. Try lowering the quality setting.

To improve the chances of a successful stitch, please follow these steps:

• Use the Auto Pano feature, which will optimize the camera and panorama settings
• Avoid starting the Panorama shot with the drone facing the sun

Once the panorama is stitched, you will be presented with the below interface:

Pausing a mission

Pausing a mission can be done by tapping on the pause button in the left bar.

Point of interests

When adding a new POI, all waypoints which have no assigned POI will have their heading setting adjusted in order to target the new POI.
To drag a POI, do a long press on the POI, then move it around. This will automatically adjust the heading setting of the waypoints that are currently targetting the POI.
To view the POI settings, tap on the POI.

You will be able to adjust the POI’s altitude which is used for the “Focus POI” waypoint gimbal setting.
To delete a POI, while the POI settings window is displayed, tap on the top left corner trash icon. Deleting a POI will automatically reassign nearest POIs for waypoints which had the now-deleted POI in target.

Regaining control

Whenever the drone flies autonomously, you can regain control instantly at any time using the remote controller’s flight mode switch.

• For newer drone models (Mavic, Phantom 4, Spark, Inspire 2), toggle the flight mode switch from “P” to “S”(sport) mode in order to regain control. You may switch back to “P” mode afterwards.
• For Mavic Mini 1, use the flight mode button in the top bar to switch from “P” to “S”(sport) mode in order to regain control. You may switch back to “P” mode afterwards. In addition, by default the RTH button on the remote controller can be used to pause an autonomous flight.
• For older drone models (Phantom 3, Inspire 1), toggle the flight mode switch from “F” to “P” mode in order to regain control. You may switch back to “F” mode afterwards.

Running a mission

Press the “Play” button located in the left button bar to show the mission preflight report. If the mission is valid, you will be able to tap the “Start” button in the report window to start the mission.
Before starting the mission, you can also select a specific starting waypoint.

Running a track session

Select the object you wish to track on the video preview using the Pinch gesture (with 2 fingers, see image below).

When you are happy with the selection, release your fingers from the screen and Track will automatically start.It is recommended to start Track while the aircraft is airborne.To select a different object, simply start the procedure again.Info To recenter the current selection, double tap where you want the new object center to be on the video preview.
For optimal tracking, ensure the background scene is not too cluttered and that there is enough contrast between the tracked object and its surroundings.
It is also important to select your object carefully.

Settings

Info

Simulator mode

The Simulator mode lets you try the Litchi flight modes without actually flying the drone in the real world. A connection to the drone is however still required.
Simulator mode can be enabled with a long press at the center of the top bar.

The top bar’s background color will change to purple to indicate that the drone is in Simulator mode.
Once enabled, you can fly the drone virtually, the rotors will not spin up when taking off.
Disable Simulator mode using a long press again at the center of the top bar. The drone must then be restarted if you wish to perform a real flight.

Status bar

Stitching a panorama outside of litchi

Here is a non-comprehensive list of software you can use to stitch the photos together outside of Litchi:

Stopping a mission

Stopping a mission can be done by switching the RC S1 switch from top position to middle position and then back to top position.

Stopping focus

Stopping a Focus session can be done using the red stop button in the left button bar.

Stopping follow

Stopping orbit

Stopping an Orbit session can be done using the red stop button in the left button bar.

Stopping panorama

Stopping a Panorama shot can be done using the red stop button in the left button bar.

Stopping track

Stopping a Track session can be done using the “Stop Tracking” button in the left button bar.

Track

In Track mode, Litchi uses state of the art computer vision algorithms to track a selected object on the video preview and keep it in the frame.
You have the choice to either fly the aircraft manually while Litchi keeps the object in the frame,
use the Orbit feature to instruct the aircraft to Orbit around the tracked object, or start Follow where the drone will autonomously follow the tracked object.
The aircraft rotation (yaw) and gimbal pitch angle are controlled by Litchi as well as the gimbal yaw for Inspire 1-2.
Enter the Track mode by pressing the Flight Mode icon at the top left of the Litchi screen. Select “Track”.

Warning Because Litchi decodes the video, runs the algorithms to track the object and renders the video, all of this in real-time, a high performance mobile device is required. Be sure to close all background applications and screen recorders before using Track. Video lag will kill tracking.

Virtual reality

Available in all flight modes, the VR mode immerses you into a real First Person View, the video stream appears right in front of your eyes.
You also have the ability to control the gimbal by moving your head. VR mode requires a remote controller.

To start VR mode, tap on the goggles icon located the top right corner of the video screen.
The VR mode requires the use of a phone together with external mobile VR goggles. Litchi is compatible with most VR goggles.
Below are some recommendations:

It is highly recommended to get a pair of goggles with a headstrap, not all of them comes with one.

Additionally, if your goggles expose the mobile device camera to the outside, you will be able to take advantage of the mobile device camera toggle in Litchi (except for P3 Standard).

Warning The VR mode brings you into another world, be aware of your surroundings as you will not be able to see your aircraft.

Visual mission planning with google earth

Using Google Earth Pro, you have the ability to plan a waypoint mission in 3 dimensions. This enables you to frame your shots easily and to position the camera exactly where you want it for each waypoint.
You can then import the mission into Mission Hub. To learn more about this planning method, please watch the following tutorial video.

Waypoint

Waypoint mode lets you plan a path made of several waypoints that the drone can then fly autonomously.
Classic waypoint missions can be planned as well as advanced camera moves such as Selfies and Cable Cams.
Enter the Waypoint mode by pressing the Flight Mode icon at the top left of the Litchi screen. Select “Waypoint”. You can then start editing missions.

Waypoint actions

Actions are performed when the aircraft arrives at the waypoint. There are six different waypoint actions, three of which accept an additional parameter.
You can add up to 15 different actions for each waypoint.
Important Waypoint actions are ignored when the mission “Path Mode” is “Curved Turns” as the aircraft will not stop at waypoints then.

Waypoint gimbal pitch

Litchi can control the gimbal pitch automatically during the mission, as long as the aircraft is within range of the remote controller.
To specify how the gimbal pitch should be controlled, each waypoint has a Gimbal Pitch setting which can be one of the following:

Waypoint settings

• Altitude: The altitude of the waypoint relative to the elevation of the aircraft where it took off. The waypoint’s altitude is also shown above the waypoint marker on the map.
• Speed: The speed at which the aircraft will travel from this waypoint to the next. By default the aircraft will use the mission’s cruising speed setting, but the cruising speed can be overriden for each waypoint using this setting.
  
  Warning This setting is only in effect when the aircraft is in range of the remote controller.
• Curve Size: Defines the size of the curved turn at this waypoint. A bigger size means the aircraft will start the turn earlier while travelling to this waypoint. This setting only applies when the mission setting “Path Mode” is set to “Curved Turns”. It also does not apply to the first and last waypoints as there are no turns at these waypoints.
  
  Info The path of the curve is drawn in turquoise on the map. It will update dynamically as you adjust the curve size setting.
• Heading: The direction relative to north in which the aircraft will look at when arriving at this waypoint (0° is North, 90° is East). This setting only applies when the mission setting “Heading Mode” is set to “Waypoint Defined” (“Custom” on iOS). If two consecutive waypoints have different headings, the aircraft will smoothly transition from one heading to the other while travelling from the first waypoint to the second.
  
  Info The waypoint heading is represented by the blue aircraft icon on top of each waypoint. It will update dynamically as you adjust the heading setting.
• Rotation: When two consecutive waypoints have different headings, the aircraft will smoothly rotate from the first heading to the next. This setting defines the direction in which the aircraft will rotate, clockwise or anti-clockwise.
• Gimbal Pitch: Choose between “Disabled” where the gimbal pitch control will be manual, “Focus POI” where Litchi will automatically control the gimbal pitch to keep the selected POI in the center of the frame (blue markers), or “Interpolate” where you can specify the gimbal pitch angle at this waypoint. For “Interpolate” to work, the previous or next waypoint need to be set to “Interpolate” as well. Litchi will then automatically adjust the gimbal pitch angle to start and end at the specified angles, and smoothly transition while travelling between the two waypoints.
• POI: Use this setting to change which POI a waypoint will focus on. By default, when adding a waypoint it will focus on the nearest POI, if there is one.
• Photo Capture Interval: Defines the time/distance interval in seconds/meters when two photos are taken as the aircraft moves from this waypoint to the next. The interval can be set between 0 and 100 seconds/meters. The first photo will be taken as the aircraft leaves the current waypoint. If the requested interval exceeds the camera’s capability, the photos will be taken at the maximum possible speed. By default, this setting uses the global ‘Photo Capture Interval’ mission setting’s value.
• Actions: Each waypoint can have up to 15 different actions (more details below).

Waypoints

To add a waypoint, tap anywhere on the map (make sure that the POI toggle is not on). You can add up to 99 waypoints.
To view the waypoint settings, tap the waypoint itself. To drag a waypoint, do a long press on the waypoint, then move it around.
To delete a waypoint, tap the waypoint to open its settings, then tap the minus icon at the top left corner of the waypoint settings window.
To insert a waypoint between two consecutive waypoints, tap the first waypoint of the two to open its settings, then tap the plus icon at the top left corner of the waypoint settings window.

A waypoint will then be inserted between this waypoint and the next, it will be placed exactly in the middle of these two waypoints.
Important The 3D distance between consecutive waypoints must be between 0.6m and 1999m.

Приложения для дронов: litchi

Примечания по особенностям работы с приложением litchi

Компания DJI постоянно меняет алгоритм взаимодействия дрона и приложений для его настройки и управления. В связи с этим, возможна ситуация, когда после запуска Litchi, приложение не видит дрон. В ряде случаев помогает предварительный запуск приложения DJI GO 4, и не закрывая его, запустить Litchi.

Мы рекомендуем использовать для работы с приложением Litchi устройства на базе IOS. По нашему опыту Litchi под этой операционной системой работает более устойчиво. Кроме того, в IOS возможно переключаться между разными приложениями для управления дроном налету, в то время как OS Android каждый раз требует смены приложения по умолчанию для пульта, как для USB устройства.
