QTcpSocket no more receives data after some time

[ben_m]

Hi guys !
I'm programming a little application which is used to communicate with an electronic cards trough Ethernet by using tcp/ip ! my application send commands and the card respond by "OK" or some data measured !

For each data send I wait then for the answer with waitForReadyRead(), but after some commands no more data are received and the timeout of waitForReadyRead() appears but when I analyse the Ethernet traffic, I view that the packet are send to my computer...

I use some threads which allow me to communicate with many cards, so I create my socket my qmainwindows class that then I transmit to my QThread subclass and connectTohost before call start method !

I hope you arrive to see what I mean !

Thanks
