Hidden Software-Defined Radio Capability Discovered in ESP32 Chips
Original: Various Projects Find Hidden SDR Capabilities in ESP32 Microcontrollers
Multiple independent projects have uncovered that Espressif's ESP32 microcontrollers contain previously undocumented software-defined radio capabilities. The findings, gathered on RTL-SDR.com, suggest the popular low-cost Wi-Fi and Bluetooth chip can be repurposed for radio signal reception beyond its intended functions. Hobbyists and security researchers are discussing what this means for cheap SDR experimentation and possible unintended uses.
Why now: Discovery of undocumented hardware features in one of the world's most widely used microcontrollers excites the maker and radio hacker community.
