[SOLVED] - QIODevice readyread() not raised



  • Hello,

    I'm trying to use QtSerialPort which use QIOdevice.
    I wonder why but it seems that readyread SIGNAL isn't raised.
    If I use waitForReadyRead() for testing purpose, my SLOT is executed.

    any Idea ?

    @
    void MainWindow::readConfFile()
    {
    if (port->isOpen())
    port->close();
    port = new SerialPort();

    connectionStatus = false;
    QFile file("./config.ini");
    if (file.open(QIODevice::ReadOnly | QIODevice::Text))
    {
        // some configuration file stuff
    
        if (!port->open(QIODevice::ReadWrite))
        {
            QMessageBox::critical(this,"Erreur","La communication n'a pas pu être établie...", QMessageBox::Ok);
            ui->actionConfiguration->trigger();
        }
        // other configuration stuff
        file.close();
    }
    else
    {
        port->setPort("COM1");
        if (!port->open(QIODevice::ReadWrite))
        {
            QMessageBox::critical(this,"Erreur","La communication n'a pas pu être établie...", QMessageBox::Ok);
            ui->actionConfiguration->trigger();
        }
        port->setRate(19200);
        port->setParity(SerialPort::NoParity);
        port->setDataBits(SerialPort::Data8);
        port->setStopBits(SerialPort::OneStop);
        port->setFlowControl(SerialPort::NoFlowControl);
    }
    
    connectSlots();
    

    }
    @
    SLOTS
    @
    void MainWindow::connectSlots()
    {
    connect(port, SIGNAL(readyRead()), this, SLOT(readData()));
    connect(port, SIGNAL(bytesWritten(qint64)), this, SLOT(writeData(qint64)));
    connect(port, SIGNAL(aboutToClose()), this, SLOT(connectionLost()));
    }
    @
    readData
    @
    void MainWindow::readData()
    {
    lastAnswer = port->readLine();
    qDebug("in : "+lastAnswer.toAscii());
    if (lastframe == HANDY_REQUEST)
    {
    if (lastAnswer != "")
    {
    if (lastAnswer != HANDY_CONNECTED)
    {
    connectionStatus = false;
    ui->FrameSeeking->setVisible(true);
    }
    else
    {
    connectionStatus = true;
    ui->FrameSeeking->setVisible(false);
    }
    }
    }
    }
    @

    I feel so screwed because this code was working Friday x)
    Damn I hate Mondays !

    EDIT : Ah, and maybe should I add that writing data on this serial port works fine...



  • Well...
    It seems to works again (and I didn't do anything...)
    So I bet it is the software I use to simulate COM ports,
    DAMN MONDAYS !
