Hi @Imen DAHMEN ,
Thanks for your support. I have tried LwIP_HTTP_Server_Netconn_RTOS from the example code and it works in NUCLEO-F746ZG. and also i searched example for SOCKET_API but it is not there for this NUCLEO-F746ZG board. I tried on own with help of STM example from some other board. The initialization was working fine but during entering IP address
it return the value -1
ret1 = read(conn, recv_buffer, buflen);
if(ret1 < 0) return;
and the full http-server-socket code is
void http_server_serve(int conn)
{
int buflen = 1500;
//int ret;
struct fs_file file;
unsigned char recv_buffer[1500];
/* Read in the request */
ret1 = read(conn, recv_buffer, buflen);
if(ret1 < 0) return;
/* Check if request to get ST.gif */
if (strncmp((char *)recv_buffer,"GET /STM32F7xx_files/ST.gif",27)==0)
{
fs_open(&file, "/STM32F7xx_files/ST.gif");
write(conn, (const unsigned char*)(file.data), (size_t)file.len);
fs_close(&file);
}
/* Check if request to get stm32.jpeg */
else if (strncmp((char *)recv_buffer,"GET /STM32F7xx_files/stm32.jpg",30)==0)
{
fs_open(&file, "/STM32F7xx_files/stm32.jpg");
write(conn, (const unsigned char*)(file.data), (size_t)file.len);
fs_close(&file);
}
/* Check if request to get ST logo.jpeg */
else if (strncmp((char *)recv_buffer,"GET /STM32F7xx_files/logo.jpg", 29) == 0)
{
fs_open(&file, "/STM32F7xx_files/logo.jpg");
write(conn, (const unsigned char*)(file.data), (size_t)file.len);
fs_close(&file);
}
else if(strncmp((char *)recv_buffer, "GET /STM32F7xxTASKS.html", 24) == 0)
{
/* Load dynamic page */
DynWebPage(conn);
}
else if((strncmp((char *)recv_buffer, "GET /STM32F7xx.html", 19) == 0)||(strncmp((char *)recv_buffer, "GET / ", 6) == 0))
{
/* Load STM32F7xxpage */
fs_open(&file, "/STM32F7xx.html");
write(conn, (const unsigned char*)(file.data), (size_t)file.len);
fs_close(&file);
}
else
{
/* Load 404 page */
fs_open(&file, "/404.html");
write(conn, (const unsigned char*)(file.data), (size_t)file.len);
fs_close(&file);
}
/* Close connection socket */
close(conn);
}

while (1)

}
}
and is there any STM example for websocket message transferring
I didn't find any STM example for LWIP for the STM32F407. If it there please provide the link
