This is my Environment:Microcontroller: STM32H723ZET6LWIP is used. No RTOS used.I am setting a Static IP address in the *.ioc file. I am setting the same IP address in the TCP Raw Socket Echo Server to Bind the socket. Over that I am running the Modb...

I am running a modified TCP Echo Server on the IO Board with STM32H723ZET6 MCU, and LWIP enabled on the Board. No RTOS used. I am sending a continuous sequence of Modbus requests from the ModPoll tool to the Modbus server running on the Board. But t...

How to set the number of simultaneous connections (backlog) in the Raw Socket Listen API? This is the relevant code snippet: /* start tcp listening for echo_pcb */ tcp_echoserver_pcb = tcp_listen( tcp_echoserver_pcb ); In contrast, the BSD/LWIP Socke...

This is regarding the issue I am currently handling. I am using STM3240G evaluation board to run a Modbus server having a TCP Raw socket-based echo server interface which receives Modbus request packets, sent from ModScan32 tool. ...

I’ve created an STM32 project using STM32CubeIDE and enabled LWIP and FreeRTOS. My purpose is to run a basic TCP Server program on the STM3240G-Eval board using BSD sockets, containing two threads. I need to use most of the BSD socket calls such as l...

OK, in that case, I've to use a full featured TCP/IP stack. Could you please mention what I need to check for this purpose? Any option is available from STM32CubeIDE? Do I have to enable FreeRTOS in STM32CubeIDE, and disable LWIP?

I am using STM32CubeIDE and it has compiled and also running. I have used the debugger in the same IDE and have confirmed that the new IP has in fact been set in the LwIP_change_ip_cfg(..) function. I've replaced "_" with "-" for security reasons, du...

Thanks for the reply. I've tried it but found that it was not working out. I've used Modbus to send the new IP address from the client machine to the server board. Then I'm calling the relevant functions as suggested. I've confirmed that the new IP i...

I have included the main.c and main.h from the specified path, but there are lot of compilation issues. I am working on that. Since this effort is going to take lot of time, I suspect the echo server only for just a few numbers of modbus responses, p...

I have created a new project and included the TCP Raw Socket Server files from the specified path (STM32CubeH7/Projects/NUCLEO-H723ZG/Applications/LwIP/LwIP_TCP_Echo_Server/Src/main.c at master · STMicroelectronics/STM32CubeH7). Since I have created ...
