Reverse engineering ESP32 Wi-Fi driver: the road ahead
Estimating the effort needed to re-implement the Wi-Fi driver
This is the fifth article in a series about reverse engineering the ESP32 Wi-Fi networking stack, with the goal of building our own open-source MAC layer. We wrote some code that implements association with an open access point and then connects the transmit and receive functions to the ESP32 IP networking stack. Our current approach of reimplementing the radio initalization, is to one-by-one replace each function with our own implementation, then test that it can still connect to the AP and be pinged.
