Thank you to Peter Holzhauser for writing in and sharing with us his latest open-source project, 'ESPsoup'. Peter has written in previously to share his Android app, V2X2MAP, which detects and plots vehicle V2X (car-to-car) communications used by some modern cars. His new project, ESPsoup, combines an ESP32-C5 and a connected PC or phone into a fully featured scanner for the 2.4 GHz and 5 GHz bands.

ESPsoup has various features including a live spectrum view up to 80 MHz wide, a sweep mode to monitor larger bandwidths, a GPS-enabled heatmapping tool, Bluetooth analysis tools, an AirTag detector, WiFI analysis tools, a car-to-car V2X monitor, a smart home sensor reader, a drone remote ID detector, a microwave oven detector, and an analog FPV video demodulator and display.

The website notes that if you want to monitor multiple FPV drone video channels, up to eight ESP32-C5s have been tested to work together on a single USB hub connected to a PC.

Peter notes that he is planning to add RTL-SDR support to ESPsoup in approximately two weeks, so keep an eye out on their website for updates.
