Qserialport Arduino garbage data

[danieldil]

I am attempting to read through the serialport from an arduino. I just receive weird characters.
Here is a screenshot

#include <QCoreApplication>
#include <QDebug>
#include <QSerialPort>
#include <QSerialPortInfo>
#include <iostream>
#include <QTimer>
#include "event.h"
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    QSerialPort *arduino = new QSerialPort();
    //QSerialPortInfo info = new QSerialPortInfo();
    //QSerialPort *arduino;
    static const quint16 arduino_uno_vendor_id = 9025;
    static const quint16 arduino_uno_product_id = 67;
    QString arduino_port_name;
    bool arduino_is_available;


   qDebug() <<QSerialPortInfo::availablePorts().length();
   //qDebug() <<info.portName();
   arduino_is_available = false;
   arduino_port_name = "";
   arduino = new QSerialPort;

  foreach(const QSerialPortInfo &serialPortInfo, QSerialPortInfo::availablePorts()){
       //if(serialPortInfo.hasVendorIdentifier() && serialPortInfo.hasProductIdentifier()){
           //if(serialPortInfo.vendorIdentifier() == arduino_uno_vendor_id){
            //   if(serialPortInfo.productIdentifier() == arduino_uno_product_id){
                   arduino_port_name = serialPortInfo.portName();
                   arduino_is_available = true;
               }
           //}
//       }
//   }

    qDebug()<<arduino_is_available;
   arduino->setPortName(arduino_port_name);
   arduino->open(QSerialPort::ReadOnly);
   arduino->setBaudRate(QSerialPort::Baud115200);

   char buf[1024];
       qint64 lineLength = arduino->readLine(buf, sizeof(buf));
       if (lineLength != -1) {
           // the line is available in buf
       for(int i = 0; i < 1024; i++){
           qDebug()<<buf[i];
        }
    }
       QString x = QString(arduino->readAll());
       qDebug()<<x;
   //event *j = new event();

   //while(true){
  // j->pulse(arduino);
  // QCoreApplication::processEvents(QEventLoop::AllEvents, 100);
  // }
    return a.exec();
}

Has anyone seen this before?

Did you try to read data using putty or other serial port terminal?
I think its also good idea to set DataBits, FlowControl and StopBits
