While STMicroelectronics do offer STM32 MCUs with wireless functionality in their "W" family, for some truly baffling reason, they have never offered a MCU with [{WiFi]] functionality, and in this day and age that does seem quite remarkable. On Oct. 1, 2024, they announced a strategic partnership with Qualcomm development, no - not a WiFi enabled STM32 but a Module which could be hooked up to a STM32 MCU and some libraries supporting this library.
The ST67W611M1 Module
Towards the middle of 2025, the new module was finally announced, the "ST67W611M1xx" one.

Building the Slave firmware
Prerequisites
This section assumes a working and up-to-date ESP-IDF installation and some sort of ESP32 development board. We will be using one based on a ESP32-C3 (single core risc-v) module.
Having the installed and configured the ESP-IDF, load the configuration by running something like:
lth@ncpws04:~$ . ~/esp/esp-idf/export.sh
Creating, configuring and building
First step is to create a new project, which will be done automatically (assuming a working ESP-IDF installation):
lth@ncpws04:~/tmp$ idf.py create-project-from-example "espressif/esp_hosted:slave" Executing action: create-project-from-example NOTICE: Example "slave" successfully downloaded to /home/lth/tmp/slave Done
Next up, we will set our target MCU:
lth@ncpws04:~/tmp$ cd slave/ lth@ncpws04:~/tmp/slave$ idf.py set-target esp32c3 Adding "set-target"'s dependency "fullclean" to list of commands with default set of options. Executing action: fullclean Build directory '/home/lth/tmp/slave/build' not found. Nothing to clean. Executing action: set-target Set Target to: esp32c3, new sdkconfig will be created.

We can now move on to configuring the project. Run:
lth@ncpws04:~/tmp/slave$ idf.py menuconfig
First step is to configure the "Serial flasher config" to match the flash available on the development board.
Final step is building and flashing:
lth@ncpws04:~/tmp/slave$ idf.py build flash monitor
