[SOLVED] QString.Contains Code works only with break point, does not work if no break point

[Sen Li]

I am a beginner on QSerialPort Terminal Example.
Whenever my sensor initialization happens, SerialPort should receive data string that contains the menu selection string SenInitialMenuString as shown below.

Here is my code:

void MainWindow::readData()
{

QString SenDataString;
QString SenInitialMenuString = "------SparkFun SPI Shortcut------\n\r\n\rMAIN MENU:\n\r(1) Actions\n\r(2) Settings\n\r\n\r->";

QByteArray data = serial->readAll();
console->putData(data);

SenDataString = data;
if(SenDataString.contains(SenInitialMenuString))
{
    qDebug("\nThis is the %d time initialization", ++NumOfInitial);
    SenFakeKey = new QKeyEvent(QEvent::KeyPress,Qt::Key_1,Qt::NoModifier, "1",false,1);
    console->SenFakeKeyPressEvent(SenFakeKey);
}

}

---

However, this code works very well only if I add a break point at the line of
" if(SenDataString.contains(SenInitialMenuString))",
whenever I run the code with no break point, it will pass it like it was never there.

Could anyone help me find out what is going on ?

Thanks!

I added a delay function before reading the serial port,

console->SenDelay(70);
QByteArray data = serial->readAll();

now everything is working.
