NXPTM M522XX, KINETIS and i.MX RT / Modbus TCP/IP
« on: December 11, 2008, 08:49:23 AM »
Hi every one !
I have try to do some modbus TCP/IP communication for my project.
The modbus TCP is only a send or reaceave of data by TCP/IP on port 502.
I have try to do the serveur ( that mean that the freescale microchip listen for connections) and everything is ok
Now, i have try to do the oposite, that mean, that the frescale must be the client ( i have to connected me to a computer where a server is on)
i have use wireShark to see the different tcp frame.
the connection is o, but when i send some data, i see on wireshark that it is a warning about "retransmission" and my server only see few frame.
My vision is that i didn't ACK.
i can send a part of my code, have you got any idea before ?!
Thanks for reading
