Problem in QTcpSocket

Hi,
I am facing a problem in QTcpSocket.
I need to send consecutive separate packets in network. To send the packets i am using write operation followed by a flush and followed by write once again.
socket->write(data)
socket->flush()
socket->write(data1)
when i flush the packet and execute write of data1 , then first packet will be lost. If i remove the flush then in same packet data and data1 is passed .
I need to pass two packets separately without loosing any of them. Please can anyone tell me how can i accomplish it???

Thank You
