Could you build this?
No Requires low-level hardware reverse engineering of undocumented internal registers and DSP/RF signal processing on the ESP32 silicon.
What it would actually take: Building an ESP32 SDR requires reverse-engineering the closed-source Wi-Fi/Bluetooth baseband hardware, capturing raw ADC I/Q samples via DMA buffers, and writing real-time DSP pipelines in C/C++ and ESP-IDF. It demands specialized expertise in RF engineering, digital signal processing, and microcontroller register-level hacking.
