Hi all

Currently, I am trying to use a Mavic Air to get pictures taken by the drone. But I follow the steps to connect remote control with windows pc, always failure. My environment is:
*Windows 10 x64 pro.
*Visual Studio 2017.
*DJI Assistant 2 Installed.
If anyone knows how to check or solve the connection issue? it would be greatly appreciated!

Thanks and cheers!

As a M100 user, I am eager to know if this Windows SDK can support M100 in the future. Thanks!

Hi, I follow this tutorial https://developer.dji.com/windows-sdk/documentation/application-development-workflow/workflow-integrate.html

I have this error:

I am using VS 2019.. Thanks for your help

I just run DJI sample code ,and I could get FPV view normal for "Mavic 2 Pro".
When i changed my Aircaft device to "Mavic 2 Zoom",it's unable to get any data ,and not callback for VideoDataUpdated .

https://github.com/dji-sdk/Windows-SDK/blob/master/Sample Code/DJISampleSources/FPV/FPVPage.xaml.cs

Line:90

        //raw data
        void OnVideoPush(VideoFeed sender, byte[] bytes)
        {
            videoParser.PushVideoData(0, 0, bytes, bytes.Length);
        }

Hi! I'm trying to get a sample application working displaying a live video feed but none of the sample applications I have tried so far has worked. I have:

• updated both the drone (V01.01.0640) and the controller (V01.01.0410) to the latest version through DJI Assistant 2 For Mavic
• have the latest version of windows-sdk (0.3.2)
• completed all the steps of installing the correct usb drivers to the controller from here
• made sure to connect the controller through the micro-usb cable to the computer before turning the controller on but the live video still wont play.
• I have read #32 and I'm not using the smart controller

This is how my device manager looks:
Basic things like getting the name of the drone works fine:
but the video stream wont work:

I got the sample application from here
I have also tried running both examples in this tutorial but it also had the same problem. Thanks for any help!

Hi, I plan to feed each frames of video took by FPV camera to opencv in real time to do some analysis. I found that the ReceiveDecodedData is handled by SetSurfaceAndVideoCallback, so I assume there is a loop inside this function to continuously capture the incoming data. My question is, how do I handle ReceiveDecodedData by loop(while or for). Or if you can provide sample code that meet my goal then that will be awesome. Thanks.

Hi, I am trying to use the virtual joystick to operate my mavic air, but there is no response after I call the method. The following is how I call it:
private void forward(object sender, RoutedEventArgs e) { DJI.WindowsSDK.DJISDKManager.Instance.VirtualRemoteController.UpdateJoystickValue(0,0, 1,0); }
to have the drone fly forward, and this function will be called by set the Click of a xaml button points to this function. Can you help me with this issue?

I've cloned Windows SDK repo, open the sample solution with latest visual studio, fixed the dll ref for Windows SDK x86, build the solution on x86 and activated the sample app with my key.

I've turned on WiFi mode on my DJI Mavic Air and connected my laptop to its WiFi, but nothing get displayed on the FPV screen:

posted as well on stackoverflow.

Can you provide download image or video from storage?like DJIMediaManager in MobileSDK。 gz#24242

So I have this code:

            Task<ResultValue<GimbalAttitudeRange?>> tskGimbalGet = DJISDKManager.Instance.ComponentManager.GetGimbalHandler(0, 0).GetGimbalAttitudeRangeAsync();
            await tskGimbalGet;
            System.Diagnostics.Debug.WriteLine("Gimbal range max yaw: " + tskGimbalGet.Result.value.Value.yaw.max.ToString());
            System.Diagnostics.Debug.WriteLine("Gimbal range min yaw: " + tskGimbalGet.Result.value.Value.yaw.min.ToString());

            System.Diagnostics.Debug.WriteLine("Gimbal range max roll: " + tskGimbalGet.Result.value.Value.roll.max.ToString());
            System.Diagnostics.Debug.WriteLine("Gimbal range min roll: " + tskGimbalGet.Result.value.Value.roll.min.ToString());

            System.Diagnostics.Debug.WriteLine("Gimbal range max pitch: " + tskGimbalGet.Result.value.Value.pitch.max.ToString());
            System.Diagnostics.Debug.WriteLine("Gimbal range min pitch: " + tskGimbalGet.Result.value.Value.pitch.min.ToString());

but it returns this:

Gimbal range max yaw: 0
Gimbal range min yaw: 0
Gimbal range max roll: 0
Gimbal range min roll: 0
Gimbal range max pitch: 0
Gimbal range min pitch: -90

which suggests that the gimbal can only change pitch. I tried rotating on the yaw axis anyways and got a PARAM_OUT_OF_RANGE error. Am I doing something wrong? Does this work on the android SDK?

Because our app will crash.The SDK internal error was located through the dump file, but we don't have its PDB file to find the problem exactly.

I followed the instructions given on the Camera Application Tutorial on this DJI documentation link.

I got this error while executing the program.

A System.IO.FileNotFoundException on DJIVideoParser.Parser()

HI,

I am using following function. What should be value of parameter ProductIndex?

VideoFeeder.GetPrimeryVideoFeed(int ProductIndex)

Thanks,
Savan

Hi the dll file only can be used by a UWP? can't use in a cpp?

I tried installing the WinUSB driver for my Mavic 2 enterprise remote controller using Zadig, but the controller was not detected in the COM ports of my computer. Attached is a screenshot of Zadig showing no devices found.

Has anyone ran into this before?

my app is working fine on my development Windows 10 PC,but when i release my app,that always crash when i init sdk ,that it's so bad for my customer ,please checkout issue.

The DJIVideo-Parser has some 3rdParty Libs that are not 64 bit (e.g. avcodec.lib,avformat.lib,swscale.lib,avutil.lib)

Any chance of of having additional DJI drones supported (e.g. M series or P4 pro)?

Thanks

Is UWP SDK for Spark on the roadmap?

Do I understand correctly from dji-devs answer in this issue #32 that the Windows SDK does not work with the Smart Controller?

when I building DJISDKSample in VS studio 2019, I encounter error "No certificate found with the supplied thumbprint: 1284217E2639D5E6101420BF06002B38EBA72D32".
How should I fix this?

Can help publish the publish visual inertial odometry pose output
or publish current video feed(15-30hz) and imu data(200-400hz) for running visual inertial odometry at PC side?

Regards
Shenghai Yuan

Hi! The Mavic 2 enterprise dual is supposed to support the resolution 336 x 256 but the enum VideoResolution doesn't contain that resolution and I can't find any thermal specific resolution setter.

Hi,

I have DJI Pro developer license. I downloaded latest SDK from https://developer.dji.com/windows-sdk/downloads/

But SDK is missing functions as per API Reference.
https://developer.dji.com/api-reference/windows-api/SDKManager/DJISDKManager.html

e.g. VideoFeeder Property of "DJISDKManager" class missing delegate "
VideoDataUpdatedEventHandler"

Can you please upload correct SDK?

Thanks,

Trying to run the DJIWindowsSDKSample sample code with a Mavic Pro Platinum drone, I get
"REQUEST_HANDLER_NOT_FOUND" in every button of the sample app. Does this mean that my drone is not supported?

Hi, i want to use the imu data , but i can't find the how to get in the sdk.

Hello Fellow Enthusiasts!

I may be simply overlooking the documentation and the sample code, but, I was unable to find a simple example of a flight path for the drone. I was wondering what the proper procedures are for taking off, moving, pausing, and landing (particularly auto landing). I have some code already, it runs, the drone executes, but it appears the drone does something different every time. I figured it's how I'm attempting to use the provided functions. So if there is any possibility to look at a sample flight plan, it would be greatly appreciated!

Cheers!

Do you have a clear roadmap or supporting plan for more drones?

I encountered with an error Cannot resolve Assembly or Windows Metadata file 'Windows-SDK-master\Sample Code\Debug\DJIVideoParser\DJIVideoParser.winmd' while compiling DJIWindowsSDKSample_x86.

I downloaded the SDK and followed the instruction on README.md, but it didn't work.
It seemed that DJIVideoParser haven't been compiled (even it is included in the dependencies of the sample project), and no files are generated.

This didn't help. I tried the x64 version, and I also reinstalled Visual Studio 2017, and neither of them did work.

I tried to control the drone with the virtual remote controller. But nothing happens (no Exception is thrown, the drone's (DJI Phantom 4 V2 Pro) position does not change). As mentioned in the API: the drone is flying while I send the UpdateJoystick command.

E.g. :for changing the drones altitude I use the following code: DJISDKManager.Instance.VirtualRemoteController.UpdateJoystickValue(0.5f, 0.0f 0.0f 0.0f);

Fellow Developers,

I downloaded the most recent release in hopes to update my DLLs and be able to move forward with the new SDK. I can build the project but when I try to execute my app, it errors with the following:

'DJI.WindowsSDK.DJISDKManager' threw an exception. - Inner Exception.
FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E)

I've re-pulled the repo, using both Visual Studio 2017 and the 2019 Preview, I then tried the sample SDK and got the same error. I'm currently on Windows Build 17763.292. Is there something I'm missing?

Thanks!

When I try to activate the SDK I get:

SDK_REGISTRATION_PACKAGE_ID_DOES_NOT_MATCH

Any suggestions?

I did have to generate a new package certificate to get things to build.

Hello Fellow Pilots!

I'm currently trying to take off and then get the current state of the drone. I have three buttons, one for takeoff, one for landing, and one to check the state of the drone. The launch and land work perfect, but when I try to get the state of the drone, it crashes every time. Here's my code:

private void BtnGetStatus_Click(object sender, RoutedEventArgs e)
        {
            var isFlying = flightController.GetIsFlyingAsync();
            status.Text = isFlying.Result.value.ToString();
        }

I'm all ears! Cheers!

I want to execute Waypoint Mission.

So I'm running the method and checking the error message in the following order.
Init Mission -> SetGroundStationMode -> LoadMission -> GetLoadedMission -> UploadMission -> StartMission

There was no problem until LoadMission, but there was a problem with UploadMission.

The waypoint is uploaded one by one, uploaded to the last mission and returned to the "READY_TO_UPLOAD" state, or the "UPLOADING" state is maintained.

The code used is the one that successfully executed Waypoint Mission in MAVIC 2 ENTERPRISE.

code:

private async void Mission_execute(object sender, RoutedEventArgs a)
        {
            BoolMsg yn = new BoolMsg();
            yn.value = true;
            SDKError err = await DJISDKManager.Instance.ComponentManager.GetFlightControllerHandler(0, 0).SetGroundStationModeEnabledAsync(yn);
            Debug.WriteLine("GSM err : " + err.ToString());
            DJISDKManager.Instance.WaypointMissionManager.GetWaypointMissionHandler(0).StateChanged += Waypoint_Mission_State;

            err = DJISDKManager.Instance.WaypointMissionManager.GetWaypointMissionHandler(0).LoadMission(this.WaypointMission);
            if (err != SDKError.NO_ERROR)
            {
                String dialogMsg = "Failed to Load => " + err.ToString();
                Debug.WriteLine(dialogMsg);
                return;
            }
            else Debug.WriteLine("Success to Load");

            err = await DJISDKManager.Instance.WaypointMissionManager.GetWaypointMissionHandler(0).UploadMission();
            if (err != SDKError.NO_ERROR)
            {
                String dialogMsg = "Failed to upload => " + err.ToString();
                Debug.WriteLine(dialogMsg);
                return;
            }
            else
            {
                Debug.WriteLine("Success to Upload");
                DJISDKManager.Instance.WaypointMissionManager.GetWaypointMissionHandler(0).UploadStateChanged += Upload_State;
            }

            err = await DJISDKManager.Instance.WaypointMissionManager.GetWaypointMissionHandler(0).StartMission();
            if (err != SDKError.NO_ERROR)
            {
                String dialogMsg = "Failed to start mission => " + err.ToString();
                Debug.WriteLine(dialogMsg);
                return;
            }
            else Debug.WriteLine("Success to Start");

        }

My development environment is like this:
OS : Windows 10
IDE : Visual Studio 2019
Development Language: C#
Drone: MAVIC 2 ZOOM (Firmware: V01.00.0510(latest firware)) & MAVIC AIR
SDK Version: 0.3.1

Hey Team,

Currently trying to create applications utilizing the Mavic Enterprise Dual via Windows SDK, and cannot get any video feed via the two sample applications provided or through other attempts to configure and obtain the feed.

The SDK states that it supports the Mavic Dual, but through some forum information from other members and the difficulties we have had, its seeming like that is not the case.

I've only found bits and pieces of those developing for the dual, none of which were success stories.

Could the dev team or others confirm if the M2ED is supported in the Windows SDK, or any help/direction in obtaining the feed in the sample applications or custom applications?

Thanks!

Hi! I'm trying to get the live feed from the thermal camera. I'm currently running the code that's under the section "Implementing the First Person View" in this article and have added this:

public MainPage()
{
    ...
    Task.Run(enableThermal);
}

private async void enableThermal()
{
    // Wait until camera has booted
    await Task.Delay(TimeSpan.FromSeconds(5));

    CameraDisplayModeMsg msg = new CameraDisplayModeMsg
    {
        value = CameraDisplayMode.THERMAL_ONLY
    };
    DJISDKManager.Instance.ComponentManager.GetCameraHandler(0, 0).SetCameraDisplayModeAsync(msg);
}

But nothing happens when I run it. To get the reason why it failed I ran this:

Task<SDKError> tsk = DJISDKManager.Instance.ComponentManager.GetCameraHandler(0, 0).SetCameraDisplayModeAsync(msg);
await Task.Delay(TimeSpan.FromSeconds(1));

System.Diagnostics.Debug.WriteLine("Tsk status: " + tsk.Result.ToString());

Then I got: Tsk status: REQUEST_HANDLER_NOT_FOUND
I also tried running this:

Task<SDKError> tsk = DJISDKManager.Instance.ComponentManager.GetCameraHandler(0, 0).SetVideoResolutionFrameRateAsync(new VideoResolutionFrameRate { resolution = VideoResolution.RESOLUTION_1920x1080 });
await Task.Delay(TimeSpan.FromSeconds(1));

System.Diagnostics.Debug.WriteLine("Tsk status: " + tsk.Result.ToString());

But then I got: Tsk status: SYSTEM_ERROR. So maybe this is a problem with async tasks in general?

Hello Mavic friends!

Currently, I am trying to use a Mavic Air in a production environment. To be able to maximize performance and productivity, I need to be able to get pictures taken by the drone on to the computer that is controlling it. I almost have the programmatic flight down, but I need to be able to get the pictures off. I don't believe that there is anything currently in the SDK for making a connection the storage, but it would be a nice feature (especially considering it is in the mobile SDK).

If anyone knows how to make any sort of connection (SSH, FPT, SFTP, TELNET, etc) it would be greatly appreciated!

Thanks and cheers!

Hello. I used to use the bebop. It supports the various language.
I want to move to DJI. It seems like it is very complex rather than Bebop python sdk.
Could you provide any simple example using by Virtual Remote controller?
I usually use the vision based approach rather than GPS.
Thank you.

I noticed on the latest release notes that the Mavic 2 Enterprise was now supported for the Windows SDK. Where can I find the USB authority configuration for this product?

Hi,
I was wondering the exact meaning of unit of latitude and longitude used in this SDK. As I know, 1 degree is about 69 miles when we talk about geology, it will be unreasonable if we apply this unit. So I was wondering what does the degree here means, like 1 degree = ?. In addition, I also want to know the start point of the coordinate system. Is it a ego-centric coordinates system or it starts from where the drone taking off? Thanks!

The sample application will not display the video from my Mavic Air over wifi. Is this supported? I can't get the video feed to display in my own UWP application either following the integration instructions exactly.

Onvideopush recieves a populated byte array but it wont display on my SwapChainPanel.

DJISDKManager.Instance.VideoFeeder.GetPrimaryVideoFeed(0).VideoDataUpdated += OnVideoPush;

Also for some reason this is never called. The converted RGBA frame is what I'm most interested in. Is there some way to get this callback to work?

//Decode data. Do nothing here. This function would return a bytes array with image data in RGBA format.
private static void ReceiveDecodedData(byte[] data, int width, int height){}

Is there a support for multiple drone connections? in example, making multiple flight plans and ordering different drones against each flight plan. gz#24427

After the drone connects I do the following:

fc = DJISDKManager.Instance.ComponentManager.GetFlightControllerHandler(0, 0);
fc.AltitudeChanged += Instance_AircraftAltitudeEvent;
fc.VelocityChanged += Instance_VelocityEvent;

and the event handlers look like this:

        private void Instance_AircraftAttitudeEvent(object sender, Attitude? value)
        {
            if(value.HasValue)
            {
                Attitude att = value.Value;
                System.Diagnostics.Debug.WriteLine("Attitude event: " + att.pitch + " " + att.roll + " " + att.yaw);
            }
        }

        private void Instance_VelocityEvent(object sender, Velocity3D? value)
        {
            if (value.HasValue)
            {
                Velocity3D velocity = value.Value;
                System.Diagnostics.Debug.WriteLine("Velocity event: " + velocity.x + " " + velocity.y + " " + velocity.z);
            }
        }

But the output I get is only this:

Velocity event: 0 0 0
Attitude event: 7.5 -0.2 -13.2

Regardless of how much I fly around.

Is the Mavic Mini a supported device?

The current FFMPEG pixel format used by the video parser is PIX_FMT_RGBA, which is 4 bytes per pixel. Since the alpha byte is always 0xff, you can save 25% of your buffer space by using PIX_FMT_RGB24 instead. You will need to change all the "* 4" to "* 3" (or define BYTES_PER_PIXEL and use that instead), plus change the VideoFeedRenderer::HandleImageTexture to use GL_RGB instead of GL_RGBA.

Hi, I'm testing Windows SDK 0.3.1. I noticed there's a bug in api.

in class VirtualRemoteController,
the method
void UpdateJoystickValue(float throttle, float roll, float pitch, float yaw)

parameters roll and yaw are misplaced.
for example, doing UpdateJoystickValue(0,1,0,0) makes mavic air rotate about Z-axis(yaw).
and UpdateJoystickValue(0,0,0,1) makes mavic air rotate about longitudinal (X, roll) axis.

I think it is unintended result. wish to be fixed.
