DJI MSDK Can't take off

Please, We need some solutions.


I have see another poster hving the same issue.

I have this code:

FlightControllerKey.KeyStartTakeoff.create().action({
    Log.d("takeoff","TakeOff Success")
}, { e: IDJIError ->
    Log.d( "takeoff","DJI Takeoff error: " + e.description())
})



This does not work, and the error message is null.


I also tried with this:







KeyManager.getInstance().performAction(KeyTools.createKey(FlightControllerKey.KeyStartTakeoff),


        object: CommonCallbacks.CompletionCallbackWithParam<EmptyMsg> {
            override fun onSuccess(
                    nil: EmptyMsg
            ) {
                Log.i(
                        "Monsoon Action",
                        "Taking off"
                )
            }

            override fun onFailure(
                    error: IDJIError
            ) {
                Log.i(
                        "Monsoon Action",
                        "Takeoff failed $error"
                )
            }
        }

        )



I get: Takeoff failed ErrorImp{errorType='CORE', errorCode='SYSTEM_ERROR', innerCode='', description='null', hint='error code = -7'

I also tried:



FlightControllerKey.KeyStartTakeoff.create().action({
    Log.d("Monsoon Command Execution : ", "takeoff success!")

}, { e: IDJIError ->

    val d = e.description()

   Log.d("Monsoon Command Execution : ", "takeoff error! $d")

})


I get takeoff error ! null

I am using MSDK V 5.7

    Have you tried our sample code? We have tested the sample code and have not been able to reproduce this issue. The link of sample code: https://github.com/dji-sdk/Mobile-SDK-Android-V5

    Hello

    Yes, I have looked at them, that is how i came to the codes above.

    could you provide me a code snippet to take of the aircraft , that I can call in a fragment, at a button click? Thank you.

    I am unsure if the issue lies within your code. Have you tried our sample code? Is it possible to command the aircraft to take off by calling _KeyStartTakeoff_ with the sample code?

    yes, i tried your code. However using the same code in my app leads to this issue.

     

    Please paste a relevant sample code here.

    Do I need to set the remote controller in a specific mode?

    Please advice

    Your meaning is that running our sample code is normal, but there is an issue with the app you developed yourself?

    Did you check the connectivity to the drone? It's probably disable when the drone is not connected.

    This is my final solution:

    private fun takeOff(id: String) {


        Log.d("Monsoon Command Execution :", "Takeoff")

        val callback = object :
                CommonCallbacks.CompletionCallbackWithParam<EmptyMsg> {
            override fun onSuccess(t: EmptyMsg?) {
                Log.d("Monsoon Command Execution :","start takeOff onSuccess.")
                

            }

            override fun onFailure(error: IDJIError) {
                Log.e("Monsoon Command Execution :", "start takeOff onFailure,$error")
                var e = error.description()
                if (e == "null") e = "unknown"

            }
        }

        FlightControllerKey.KeyStartTakeoff.create().action({
            callback.onSuccess(it)
        }, { e: IDJIError ->
            callback.onFailure(e)
        })

    }
