hi,

sorry for my english, but i'm french.

I use the stack LWIP with stm32F107VC.

I have create 4 TCP serveur (port 5001,5002,5003,5004).

When a connect client of port TCP (exemple 5001), i send a string (1400 bytes) every 5,4ms.

The data rate is about 2,4Mbits/s.

But the problem is, if i connecte an others client of an others port (exemple 5002), and i send an others string (1400 bytes) every 5,4ms.

then, serveur TCP generate an error of trafic TCP (look with wireshark) in a few minutes.

So

,

I want to create

4

TCP server

that can

be sent to

10Mbit / s

each.

My systick is 10Khz and my sysclock is 72Mhz

I try with board KEIL STM32C and ST STM3210C-EVAL. The problem is the same

thank

Hi,

your application based on an RTOS or standalone.
