kandi X-RAY | msdk Summary
Mass Spectrometry Development Kit (MSDK) is a Java library of algorithms for processing mass spectrometry data. The goals of the library are to provide a flexible data model with Java interfaces for mass-spectrometry related objects (including raw spectra, processed data sets, identification results etc.) and to integrate the existing algorithms that are currently scattered around various Java-based graphical tools.

I'm building a Flutter Plugin above the DJK SDK. For that, I have to implement the communication with the aircraft on the native side, and I'm doing it with Java. I'm also doing it only for Android.
One of the methods of the API is
boolean connectToAircraft(), which must return if the connection with the aircraft succeeded.
After I call
connectToAircraft() - which invokes the
DJISDKManager.getInstance().startConnectionToProduct() method, I expected to be able to use anything related to aircraft immediately, but this doesn't happen. I have to wait a few seconds before I can retrieve data from the aircraft.

According to the SDK Docs
onProductChanged is primarily used to detect when the connection status changes from only remote controller connected to a full connection between the aircraft and the SDK running on your device.
Keep in mind that when the aircraft is disconnected, this method will be called with an instance of an aircraft, but this instance will come with property
false. If you print the aircraft object to the console you will notice that if
true, it will print the aircraft name, otherwise, it will print "None".
As long for the
onProductConnect, it will be called always after
DJISDKManager.getInstance().registerApp() succeeded or after you manually connect to the aircraft with success using
DJISDKManager.getInstance().startConnectionToProduct(). In my tests, even though the app registration succeeds, the method will return
false, so you might need to check if the
SDKManagerCallback::onRegister results in
You need to listen to component change events. Unfortunately just because the product is connected it does not mean that the individual components, such as the flight controller, camera etc are connected. You will need to implement
onComponentChange and add a listener to detect when a component is connected. These don't always connect in the same order and may start to connect before or after the product is connected.
Unfortunately, DJI SDK documentation only states:
Calculate the total time of the waypoint list.
Is that in seconds? Seconds' fraction? Minutes?
The same applies to
Calculate the total distance of the waypoint list.
I couldn't deduce the right time (and distance) units since I got different values for the same set of waypoints in different map locations (!). For instance, the same equally spaced waypoints in middle-east Brazil is different when they're applied in north-west of Canada. The difference is ~15%. What's the reason?
My SDK version is 4.13.1 for Android (MSDK)....
ANSWERAnswered 2020-Oct-30 at 00:33
I've e-mailed them through email@example.com and they've answered that the distance is in meters and the time, in seconds.
About the different values for middle-east Brazil and the north-west of Canada, I have no clue.
I'm building a mission planner that will get waypoints from a user click on the map. After completing an area, he'll load and start the mission.
When I start the mission, it goes through all the waypoints, and after arrives at the last one, it comes back to the home point and lands.
The problem is: it doesn't return home, instead it lands on the last waypoint.
The code below is just a part of a POJO object...
ANSWERAnswered 2020-Oct-16 at 21:47
There are a few thing in play and a few questions that can help clarify what you are seeing:
First question, how far away from home is the aircraft when the last waypoint is reached?
For whatever reason, DJI designed the firmware such that if the aircraft is close to home (I think close it within 15m) then the aircraft lands in place. This means, if the last waypoint is close to the home point, it might already believe it is home and just land in place.
For all the software I write, I always add a specific waypoint on where I want the mission to end and use
AUTO_LAND as the finishedAction, it's removes the above issue and always guarantees the correct results (aka, no 'iffyness' because of firmware logic).
My suggestion would be to add a waypoint above the home point, it's the best solution!

You can use msdk like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the msdk component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
