I think they do this though... but it's Zephyr instead of FreeRTOS.
What I want is a Wi-Fi radio that just works like a normal part. No RTOS requirement. No framework or software libs required. Read the datasheet and go.
For some context: This is how LoRa radios work, and this is how Esp-Hosted (Official firmware from Espressif that turns the ESP into a radio IC "coprocessor") works.
I thought ESP32 does exactly the same as Nordic Softdevice model? It's just that people hardly notice, and it's perfectly fine.
To have a maintainable Firmware, with TCP/IP stack, you still need some sort of RTOS anyway.
Wireless/network stack is hard.
