Open the selected port

deleted286

How can i get the current ports on a combo box and then open the choosen port?
I want to open it when i run the program

void MainWindow::open_Serial()
{
    serial->setPortName("/dev/ttyUSB0");
    serial->setBaudRate(QSerialPort::Baud115200);
    serial->setDataBits(QSerialPort::Data8);
    serial->setParity(QSerialPort::NoParity);
    serial->setStopBits(QSerialPort::OneStop);
    serial->setFlowControl(QSerialPort::NoFlowControl);

    if (serial->open(QIODevice::ReadWrite))
    {
        qDebug() << "ttyUSB0  is Open ";
        serial->clear();
        write_Json();
        connect(serial, &QSerialPort::readyRead, this, &MainWindow::on_Serial_Read);
    }

    if(serial->isOpen())
    {
        ui->Open->setChecked(true);
    }
    else
    {
        ui->Close->setChecked(true);
     }
}

Do you think posting a question after it has answered already 1 week ago will give you another answer?

Why should I delete your post? I just asked why you open a new thread for a question which was answered for you one week ago.

No, the solved posts don't get deleted. They remain for the benefit of other forum users having same/similar issues.
It's a community driven approach, opposite to a "my problem only" driven approach
