coordinates are nan for latitude and logitude

Jasur

Hi all
Below code worked fine before.I am getting nan for latitude and longitude now.
In .pro file i have: QT += quick quickcontrols2 sql qml positioning network core
location
import QtPositioning 5.12 also i have
GPS on Android device is ON
SDK platform 30
NDK 21.3.65

My main idea is to get GPS coordinates from Android device and send to database

Page {
    property string lat
    property string lon
    property date currentTime: new Date()
    property string timeString
    property string textString
    property string photoString

    Rectangle {
        id: rect1
        anchors.fill: parent



        POST_REQ_CAMERA {
            id: demo
        }


        PositionSource {
            id: src
            updateInterval: 5000
            active: true

            onPositionChanged: {
                var coord = src.position.coordinate;
                console.log("Coordinate:", coord.latitude,coord.longitude );
                lat=coord.latitude;
                //lat=src.position.coordinate.latitude
                lon=coord.longitude;

            }

        }

        Image {
            id: photoPreview

            anchors.fill: parent
            fillMode: Image.PreserveAspectFit
        }


        Camera {

            }

            flash.mode: Camera.FlashRedEyeReduction

            imageCapture {
                id: imageSaved
                onImageSaved:  {

                    //photoPreview.source = preview
                    photoString=path
                    //demo.processImage(preview);
                }
            }
        }


        VideoOutput {
            source: camera
            //anchors.fill: parent
            //focus : visible // to receive focus and capture key events when visible
        }

        Button {

            opacity: 0.5

            Text {

@Jasur
at what position in your code do you get NaN?

Jasur

@raven-worx On a huawei mobile device, after clicking on the send button, I display the lat and lon on the text field where I get the result of the nan. In below code i get nan

text: lat + lon

raven-worx

@Jasur
and this output is still ok?

console.log("Coordinate:", coord.latitude,coord.longitude );

Jasur

@raven-worx when i choose desktop kit console.log shows me coordinates, but for android kit there is no console.log output, that is why i used

text: lat + lon

to check coordinates
