Liberating Bluetooth on the ESP32
Antonio Vázquez Blanco (Antón)
39th Chaos Communication Congress (39C3): Power Cycles · Day 1 · Saal One
In this insightful talk, Antonio Vázquez Blanco, known as Antón, from Talogic Security, unveils his extensive work in reverse engineering the undocumented Bluetooth internals of the Espressif ESP32 microcontroller. The presentation, titled "Liberating Bluetooth on the ESP32," addresses a critical gap in Bluetooth security research: the lack of affordable, low-level access to Bluetooth hardware capabilities. Antón's research aims to demystify the ESP32's dual-mode Bluetooth controller, providing the community with the tools and knowledge necessary to perform advanced security assessments and develop custom Bluetooth functionalities.
