INET TCPSocket Omnet++

Question

I want to establish a TCP connection from my application in Omnet++ to an external server.

This is my sample code

inet::TCPSocket mysocket;
        mysocket.connect(inet::L3Address("192.168.12.226"),10000);
        EV<< "Socket connection" <<endl;
        cPacket * msg = new cPacket("solve");
        msg->setByteLength(1024);  // 1K
        mysocket.send(msg);
        mysocket.close();

This code compile, but when I run my application this error appears

SetOutputGate() must be invoked before socket can be used

Error image

The example code in the TCPSocket.h is very similar.

I don't understand this error.

Any suggestions?

Thanks.

You should add:

mysocket.setOutputGate(gate("tcpOut"));
