Uri Shaked explains how he reverse engineered and emulated the ESP32 WiFi hardware at the lowest level for the Wokwi simulator.
In this deep-dive presentation given at the 2021 Hackaday Remoticon, Uri Shaked puts on his reverse engineering hat and takes us through his fantastic work on the ESP32's WiFi module internals. His strategy incorporates not just decompiling and debugging, but also directly simulating the ESP32, so that he can run code until it crashes, fix the crash in simulation, and keep repeating until it doesn't crash any more. The result is an emulation of the ESP32's WiFi hardware at the lowest level that's so complete that it can run Python web and MQTT code, completely in simulation. Amazing!

Highly recommended for its deep dive into reverse engineering and emulating proprietary wireless hardware.
