AIRCRAFT_LOCATION KeyListener sends invalid information `NaN` as lat/lon values

[brien-crean]

A KeyListener set to listen to AIRCRAFT_LOCATION changes sends invalid information after some time during VirtualStick flight. For example the below configured aircraft location listener sends NaN for the longitude and latitude values. This happens intermittently and when it does no valid information is sent afterwards. It never recovers

fun addAircraftLocationListener() {
    val aircraftLocationKey: DJIKey = FlightControllerKey.create(FlightControllerKey.AIRCRAFT_LOCATION)
    val aircraftLocationListener =
        KeyListener { oldValue: Any?, newValue: Any? ->
            if (newValue is LocationCoordinate3D) {
                val location = newValue as LocationCoordinate3D?
                if (location != null) {
                    println("latitude: ${location.latitude},longitude: ${location.longitude}")
                }
            }
        }
    DJISDKManager.getInstance().keyManager!!.addListener(aircraftLocationKey, aircraftLocationListener)
}

Please read this article, Why I have received NaN for aircraft location? You can connect your aircraft with DJI Assistant 2's simulator to mock a GPS signal.

This is happening while the simulator is running. I get valid aircraft location values from the simulator and then all of a sudden I get NaN values

It means something wrong in the simualtor then such as lost cable connection.
