WIZ107SR how to send/receive tcp/ip packets

Hey,

I’m new with wiz107sr module (but I’m very experienced in embedded programming). i read the documentation, connected to the board via config. tool & via serial.
What I don’t understand actually, if I want to send some packet via ttl(uart) to ethernet , tcp/ip packet, I have destination, port, data payload. How can I do it? How to open port? what should I do?? And from other side how can I receive packet via uart?
Could you please add some concrete example?
In addition, may be you have some host code example works with wiz107sr via uart? It will be great if you can send it to me.
Thanks,
Boris

Hi, @BorisPokutinsky

You can control the settings of destination IP address, port number and etc. with the configuration tool or serial command(and by the Ethernet network). And our hardwired TCP/IP stack in chip automatically handles packet encapsulation to send/receive payload to its destination.

Below link will help you.
