Just a few days ago, we wrote about the ESP-SDR project, which turned an ESP32 into an SDR receiver (and now SDR transmitter), but the data was streamed over UART, which couldn’t keep up with the ...

Perhaps the most exciting news of the past few weeks in the world of hardware hacking has been the unlocking of hidden SDR functionality in the Wi-Fi radios found on Espressif ESP32 microcontrollers.

Well, that was fast! Last week, we reported on two apparently simultaneous hacks using the 2.4 GHz radio inside many ESP32 variants that enabled raw access to the radio samples, turning it into a ...
