Getting current location GPS

[wilson_chan]

Hi all,

I’m writing an application that needs to get the current location of the user using QtMobility and PositionSource QML element. The code is working well with our testing Nokia 700 device; however, seems to be unable to get the current location on Symbian devices. I’ve tried with a very simple example on the documentation like:

main.qml
@import QtQuick 1.1
import QtMobility.location 1.2

Rectangle {
id:page
width : 250
height: 350
PositionSource {
id: positionSource
updateInterval: 1000
active: true
// nmeaSource: "nmealog.txt"
}
Column {
Text {text: "<==== PositionSource ====>"}
Text {text: "positioningMethod: " + printableMethod(positionSource.positioningMethod)}
Text {text: "nmeaSource: " + positionSource.nmeaSource}
Text {text: "updateInterval: " + positionSource.updateInterval}
Text {text: "active: " + positionSource.active}
Text {text: "<==== Position ====>"}
Text {text: "latitude: " + positionSource.position.coordinate.latitude}
Text {text: "longitude: " + positionSource.position.coordinate.longitude}
Text {text: "altitude: " + positionSource.position.coordinate.altitude}
Text {text: "speed: " + positionSource.position.speed}
Text {text: "timestamp: " + positionSource.position.timestamp}
Text {text: "altitudeValid: " + positionSource.position.altitudeValid}
Text {text: "longitudeValid: " + positionSource.position.longitudeValid}

    Text {text: "latitudeValid: "  + positionSource.position.latitudeValid}


    Text {text: "speedValid: "     + positionSource.position.speedValid}
}
function printableMethod(method) {
    if (method == PositionSource.SatellitePositioningMethod)
        return "Satellite";
    else if (method == PositionSource.NoPositioningMethod)
        return "Not available"
    else if (method == PositionSource.NonSatellitePositioningMethod)
        return "Non-satellite"
    else if (method == PositionSource.AllPositioningMethods)
        return "All/multiple"
    return "source error";
}

Add more folders to ship with the application, here

folder_01.source = qml/bcard
folder_01.target = qml
DEPLOYMENTFOLDERS = folder_01

Additional import path used to resolve QML modules in Creator's code model

QML_IMPORT_PATH =

symbian:TARGET.UID3 = 0xE63F200B

Smart Installer package's UID

This UID is from the protected range and therefore the package will

fail to install if self-signed. By default qmake uses the unprotected

range value if unprotected UID is defined for the application and

0x2002CCCF value if protected UID is given to the application

#symbian:DEPLOYMENT.installer_header = 0x2002CCCF

Allow network access on Symbian

#symbian:TARGET.CAPABILITY += NetworkServices
symbian:TARGET.CAPABILITY += NetworkServices Location

If your application uses the Qt Mobility libraries, uncomment the following

lines and add the respective components to the MOBILITY variable.

CONFIG += mobility
MOBILITY += location

Speed up launching on MeeGo/Harmattan when using applauncherd daemon

CONFIG += qdeclarative-boostable

Add dependency to Symbian components

CONFIG += qt-components

The .cpp file which was generated for your project. Feel free to hack it.

SOURCES += main.cpp

Please do not modify the following two lines. Required for deployment.

include(qmlapplicationviewer/qmlapplicationviewer.pri)
qtcAddDeployment()

I can see the GPS symbol is activated on the device;
However the data getting is as below:

<====PositionSource====>
positioningMethod :Satellite
nmeaSource:
updateInterval:1000
active:true
<====Position====>
latitude:NaN
longitude:NaN
altitude:NaN
speed:-1
timestamp: Invalid Date
altitudeValid: false
longitudeValid: false
latitudeValid: false
speedValid: false

Have someone met this issue before? May I know how to fix it and get all the data correctly?
Thank you.

Thanks,
