ESP-SDR Can Now Transmit

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 listen-only software defined radio (SDR) platform. That’s only half of the SDR story. Last weekend, [Murmel] got started fixing that, and released an early early version of ESP32 firmware that can also transmit , and got it working with gqrx.
