What is the expected behavior?

I want to connect ESP32-32D on another device via ModBus UDP

What is the actual behavior?

I receive this error when I try to set mb_mode_type_t to MB_MODE_UDP: ESP_ERR_INVALID_ARG

Steps to reproduce.

Create the Modbus TCP Master Example (mb_tcp_master)
Go to app_main()
Find comm_info struct
Change comm_info.ip_mode from MB_MODE_TCP to MB_MODE_UDP
Run the code

Thanks for reporting.

Hello, Alvin1Zhang,

What is the prediction for any response to assist me?

Hello @pedrohugo-psc,

The error ESP_ERR_INVALID_ARG means the argument is not supported. The UDP communication for the stack is not yet supported. In order to communicate over UDP you need to update the stack code on your side. Let me know if you need more information on how to accomplish this. I also see that you use IDF v4.4, I would recommend to use the esp-modbus latest version in your project. You need to add the line set(EXCLUDE_COMPONENTS freemodbus) to your CMakeLists.txt file as described in the readme.md file.
