Issue or Suggestion Description

Hi,
I'm having a hard time integrating the ESP-Hosted-MCU into my STM32 project. In my setup, I'm using the ESP32 as the slave and the STM32U575ZIT6Q as the host. I'm using SPI FD for communication and not using Bluetooth.
The main focus of my project is to create a UDP server that sends status messages to anyone who has subscribed. It's similar to MQTT, but much simpler. It's a semi-proprietary protocol.I tried many times to integrate it, starting with an empty project and gradually trying to resolve all compile errors, but I can't finish. I'm sorry if this is a similar request to others, but I'm the only one getting these errors, and I don't know why.
What steps should I take to get it working?
Thank you in advance to anyone who can help me.

@SohKamYung-Espressif, can you please provide (internal) reference code and notes for integration for STM32?

Hello @NicoCaciu98 ,

Properly integrating host support for STM32 is still among the pending tasks.

In the meantime, you can take a look at the link provided in this comment #46 (comment)

It is a work-in-progress repo for building the host portion of ESP-Hosted-MCU on a STM32. It provides a host/extra_components directory that contains ESP-IDF components needed by STM32 to build with ESP-Hosted.

The file docs/host_port_stm32.md has info on how to build for STM32.

any updates @NicoCaciu98 ?

Hi @mantriyogesh and @SohKamYung-Espressif thank you for the reply. I have tried many times but I can't get anything to work. I cann't get the code to compile because it seems that when I use the "prepare_project.bat" script it screws up the project on the IDE and I think don't copy correctly the files.

@SohKamYung-Espressif Have we tested or ported prepare_project.bat for stm32 on Windows?
