does this dronekit-android work for PX4?

[seantobe]

Dear all:
I am trying to develop an Android APP that can take off PX4 simulator JMAVSim. I have successfully compiled and run the code using Android Studio( following the link in "http://android.dronekit.io/first_app.html"). Am I doing it right? If I turn on JMAVSim, and run my APP, would it work? Thanks for replying.

The major issue with PX4 compatibility is changing modes. The standard method of changing modes in dronekit-android will not work. You will have to use the ExperimentalAPI and send the mavlink packet yourself. You can model it after this.

Hi:
3q for replying. I will try the way your recommanded later on. However, I cannot even connect to the JMAVSim by UDP port 14550. Please let me know what the problem is, appreciate it. I posted my code below.
Step 1: make posix_sitl_default jmavsim//start the simulator
Step2: run my APP and press the connect buttun (onBtnConnectTap)//---->cannot connect

public void onBtnConnectTap(View view) {
if(this.drone.isConnected()) {
this.drone.disconnect();
} else {
Bundle extraParams = new Bundle();
extraParams.putInt(ConnectionType.EXTRA_UDP_SERVER_PORT, 14550); // Set default port to 14550

            ConnectionParameter connectionParams = new ConnectionParameter(ConnectionType.TYPE_UDP, extraParams, null);
            this.drone.connect(connectionParams);
    }

}

I recently tested DroneKit-Android with the PX4 flight stack via their experimental api and it works well as show here.

Hello IeiuniumLux,
