[SOLVED] QUDPSocket Help
-
All I am trying to learn QUDPSocket and attempting to write an application to push data back and forth across a network between laptops. Nothing fancy just messages, but I want to send a msg from one system and catch it on the other. I found a nice example on line and it works but it seems to write and read the datagrams on the same system. So I have tried to bind the IPs of the two systems and I get nothing. I am sure I am missing something. Here is my code.
MyUDP::MyUDP(QObject *parent) : QObject(parent)
{socket = new QUdpSocket(this); socket->connectToHost(QHostAddress(“101.207.29.195”), 1234, QIODevice::ReadWrite); connect(socket, SIGNAL), this, SLOT));}
void MyUDP::WriteData()
{
QByteArray data;
data.append(“Data In”);
socket->writeDatagram(data, QHostAddress::LocalHost, 1234);
//this writes and reads fine.}
void MyUDP::WriteData(QByteArray inMessage)
{
socket->writeDatagram(inMessage, QHostAddress(“101.207.29.195”), 1234);
}
void MyUDP::readyRead()
{
QByteArray Buffer;
Buffer.resize(socket->pendingDatagramSize()); //Pending DatagramSize is size of incoming data
QHostAddress sender;
quint16 senderPort;
socket->readDatagram(Buffer.data(), Buffer.size(), &sender, &senderPort);
//Process packets here.qDebug() << “Message from : “ << sender.toString();
qDebug() << “Message Port : “ << senderPort;
qDebug() << “Message : “ << Buffer;

Can you check the network setup ? Can you check whether client box and server box in same network ? Do you have reachability to both boxes ?Are they in same network ?Can you ping each IP address from each box ?
ie.
ping 101.207.29.195 -
Difficult to see your code. I can send you the working code. Can you drop email to me ?

Just dropped an in mail for you. You can drop me an email.
