Hi guys,
I'm developing an application with Renesas Synergy (SK-S7G2 board) and I'm using Ethernet (NetX) functions.
I needed to use http client functions to send and receive data (POST and GET). But, after failing repeatedly (with netx http client functions and static 80 port), I started to use tcp/socket functions.
I've seen a lot of similar problems in the forum, but I have problems yet.

Using Wireshark, I see the right packets, but I also see a lot of junk and spurious packets (It seems that something is missing).
I'll put some of my code below.If anyone can check I'm right.
The netx_http_post_data just send data to server specified. And the netx_http_get_data send data to other server and wait reply (like a validation).
Am I forgetting something? That does not seem to be totally right. And sorry, I am noob on Renesas Synergy and NetX.
