why RecvOneOrMore()can't receive data

[zhjiawei_cn]

Following is my code to test socket on Symbian OS, I send a package which length is 6 and data are all 0, the server will back a package, but why I can't receive the package? Thanks a lot!!

void CTcpEngine::RunL()
    {
    switch(iChannelState)
        {
    case EChannelConnected:
        {
        if (iStatus==KErrNone)
            {
            // Connection was made successfully
            iStatusText=_L("\nConnection established");
            NotifyProgress();
            
            
            TText8 pack[6] = {0, 0, 0, 0, 0, 0};
            iWriteDataBuffer.Append(pack, 6);
            
            iChannelState=EChannelSending;
            iSocket.Send(iWriteDataBuffer, 0, iStatus);
            SetActive();
            }
        else
            {
            iStatusText=_L("\nFailed to connect");
            NotifyProgress();
            }
        }
        break;

    case EChannelSending:
        {
        // Receive data from the "server"
        iStatusText=_L("\nSent data");
        NotifyProgress();

        iSocket.RecvOneOrMore(iReadDataBuffer, 0, iStatus, iRecvLen);
        iChannelState=EChannelReceiving;
        SetActive();
        }
        break;

    case EChannelReceiving:
        {
        if (iStatus == KErrNone)
            {
            // Data was received successfully
            iStatusText=_L("\nReceived data");
            NotifyProgress();
            // Display received data in user interface
            //iStatusText=iReadDataBuffer;
            //NotifyProgress();
            }
        else
            {
            iStatusText=_L("\nError reading data");
            NotifyProgress();
            }

        iStatusText=_L("\nClose the connection...");
        NotifyProgress();

        iSocket.Close();
        iStatusText=_L("\nEnd of test.");
        NotifyProgress();
        }
        break;
    default:
        break;
        }
    }

it seems your code not problem, you'd better confirm that server send response data.
The best way is use ethereal catch data.

I test catch data from server on Windows, no problem.
