    While building the btchat example in it.
    I m getting the following errors..

    Re: Qt Mobility 1.2 connectivity

    In Qt Mobility 1.2

    while building systemInfo project gives following errors :
    qsystemdeviceinfo.cpp: In member function 'QFlags<QtMobility::QSystemDeviceInfo::KeyboardType> QtMobility::QSystemDeviceInfo::keyboardType()':
    qsystemdeviceinfo.cpp:522: error: 'class QtMobility::QSystemDeviceInfoPrivate' has no member named 'keyboardType'
    qsystemdeviceinfo.cpp: In member function 'bool QtMobility::QSystemDeviceInfo::isWirelessKeyboardConnected()':
    qsystemdeviceinfo.cpp:534: error: 'class QtMobility::QSystemDeviceInfoPrivate' has no member named 'isWirelessKeyboardConnected'

    qsystemdeviceinfo.cpp:584: error: 'class QtMobility::QSystemDeviceInfoPrivate' has no member named 'lockStatus'

    This means that QSystemdeviceInfo class is updated in Qt Mobility 1.2 but QSystemDeciceInfoPrivate class is not updated accordingly..
    why is it so????
    anybody facing the same problem?

    How to build QSystemInfo project ?


    Thanks ...

    Re: Qt Mobility 1.2 connectivity

    You are missing Qt mobility header and library in your SDK. Are you using QtSDK 1.1 or Symbian^3 SDK?

    Re: Qt Mobility 1.2 connectivity

    Have you used ?
    CONFIG += mobility
    MOBILITY += systeminfo

    For bluetooth you have to change or add MOBILITY += connectivity

    If you have checked these and still getting the error then probably porting error mibility 1.2 to QTSDK

    Re: Qt Mobility 1.2 connectivity

    Hi,
    Ok, now I got it what you are trying to do. You can't use Qt mobility 1.2 with QtSDK for example 1.1 (where we have Qt mobility 1.1)

    It is very difficult to make it working in that way.
    One option could be use Carbide C++ and Symbian^3 SDK and there you can use the SDK plugin for Qt mobility 1.2 (but I again heard there are some BT related stuff and one NFC header files are missing there).

    Re: Qt Mobility 1.2 connectivity

    Like I mentioned, it is difficult with QtSDK version 1.1
    One thing you could do
    Download the new plugin from http://www.forum.nokia.com/info/sw.n...ian_3_SDK.html
    and install it to for Symbian SDK

    And from Symbian SDK you copy all the needed files to QtSDK 1.1 (should put under epoc32 folder)
    I don't see any other way now, Does anybody know other tips, please post here

    Re: Qt Mobility 1.2 connectivity

    Check that your certificate can be used to sign all capabilities needed by your application?

    Re: Qt Mobility 1.2 connectivity

    I am using self signed certificate.
    with all tha capabilities LocalServices \
    NetworkServices \
    ReadUserData \
    UserEnvironment \
    WriteUserData

    Is it not sufficient to use self signed certificate?

    Thanks..

    Hi,

    I think this will help you on some extent.

    https://projects.forum.nokia.com/QtM12bSymb
    There is sis file for Qt 1.2 and also if you configure it you can build app by using BT and NFC
