The ESP32 is a low-cost microcontroller with Wi-Fi connectivity. Currently, the Wi-Fi MAC layer of the ESP32 is closed-source. This project aims to change that: by reverse engineering the hardware registers and software, we can build a networking stack that is open-source up to the hardware, instead of having to use the proprietary Wi-Fi binary blobs.
This will improve security auditability, open up the possibility for features not supported in the proprietary implementation (for example, standards-compliant mesh networking), improve interoperability and make research into Wi-Fi networks with lots of nodes more affordable.
