Getting current location on Symbian^3 (Anna, Belle) devices

  • 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 N9 device; however, seems to be unable to get the current location on Symbian devices. We've tried with a very simple example on the documentation like:

    import QtQuick 1.1
    import QtMobility.location 1.2

    Rectangle {
    id: page
    width: 350
    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: " +}
    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/untitled = qml

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


    symbian:TARGET.UID3 = 0xE5101660

    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 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.


    I can see the GPS symbol is activated on the device; however, after waiting for a long time, the application cannot get the location. Code is tested on Nokia X7 and 603.

    Have someone met this issue before?


  • Good day

    I'm trying exactly the same example and I'm not getting anything, also in the .pro file I've added the location capability, but nothing is happening

    any suggestions?


  • Try adding "LocalServices ReadUserData WriteUserData ReadDeviceData WriteDeviceData" to the symbian capabilities, those are required capabilities according to the "docs":

  • Hi all,

    Search for some posts - there is a specific bug in PositionSource which causes your device to look for GPS data and hanging up on it if no GPS signal is received (hence you see GPS icon).
    This means outside your code will work fine, but PositionSource won't automatically look for non-GPS sources...

    Best workaround is to go with Qt C++ and write custom nonGPS PositionSource.

    Problem will be again if you rely on GPS more - to code something to manage "blending" different sources...
