Threading with QNetwork Problem (UDPSocket)

[BadHombre]

Hi Guys :)
I need some Help with a problem i have right now ...
Currently i'm sendig data from a raspberry Pi to a Port where i am trying to recieve this data qith a qt GUI ..
Also Because the recieving is not the only task of the GUI i created a Thread..

My Problem is that i am recieving the First Value... and it's also the right value but then i get the message
QNativeSocketEngine::readDatagram() was called not in QAbstractSocket::BoundState or QAbstractSocket::ConnectedState
and no Values anymore ...
I Created the Thread via signal and Slot

main:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

QThread cThread;
recievesesnsordata cObject;
cObject.DoSetup(cThread);
cObject.moveToThread(&cThread);

cThread.start();

MainWindow w;
w.show();
    return a.exec();
}

recieve Header File:

#ifndef RECIEVESESNSORDATA_H
#define RECIEVESESNSORDATA_H

#include <QObject>
#include <QDebug>
#include <QThread>

class QUdpSocket;
class recievesesnsordata : public QObject
{
    Q_OBJECT
public:
    explicit recievesesnsordata(QObject *parent = nullptr);
    void DoSetup(QThread &cThread);

public slots:
    void DoWork();

private:
    QUdpSocket *udpSocket2;

};

#endif // RECIEVESESNSORDATA_H

recieve.cpp

#include "recievesesnsordata.h"
#include <QtNetwork>

recievesesnsordata::recievesesnsordata(QObject *parent) : QObject(parent)
{

}


void recievesesnsordata::DoSetup(QThread &cThread)
{

    connect(&cThread, SIGNAL(started()),this,SLOT(DoWork()));
}

void recievesesnsordata::DoWork()
{

    while(true)
    {

        udpSocket2 = new QUdpSocket;
        udpSocket2->bind(45455,QUdpSocket::ShareAddress);

        QByteArray datagram;
        datagram.resize(udpSocket2->pendingDatagramSize());
        udpSocket2->readDatagram(datagram.data(), datagram.size());
        QList<QByteArray> test;
        test.push_back(datagram.data());



    }

}



}

Thanks for your help in advance i really appreciate it !

You should not set up an infinite loop but rather connect to QUdpSocket::readyRead

Also, you are creating 1 new socket every iteration (and leaking it)

the problem is i want that the thread is running in the background and recieve all the time data ... that's why i am using a infinite loop... i tried to create a new socket outside of the infinite loop but the problem is that i'm getting an exception because of the memory ... do you have an idea how i could realize this ?
