ESP32 open MAC

During the past year, quite a lot happened within the esp32-open-mac project (and within the broader ESP32 reverse engineering community in general), both code-wise and event-wise.

First, a short recap of what this project is doing: the Wi-Fi stack for the ESP32 (a popular, cheap microcontroller) is provided through a binary blob.

This is a more technical blob post about a specific aspect of the ESP32 Wi-Fi hardware; see previous blog posts for a more general overview.

We’re writing an open source 802.11 (Wi-Fi) stack for the ESP32.

Today, we gave a talk at 38C3 about our work on reverse engineering the ESP32 Wi-Fi hardware with the goal of creating an open source MAC stack.

I gave a talk at the Riot Summit 2024 about reverse engineering the ESP32 Wi-Fi hardware.

Today, I gave a talk about this project at the 22nd Gulaschprogrammiernacht (a hardware/software hacking conference in Germany).

This is the fourth article in a series about reverse engineering the ESP32 Wi-Fi networking stack, with the goal of building our own open-source MAC layer.

This second article talking about reverse engineering the ESP32 Wi-Fi RX registers and showing of the first proof of concept that was able to connect to an access point was posted on the Zeus WPI blog: https://zeus.ugent.be/blog/23-24/esp32-reverse-engine…
