Sniffing “Crazyradio” NRF24 Signals with a HackRF Blue

Thanks to we’ve heard about this project in which experimenter Arnuad has been using his new HackRF Blue to sniff and debug the communications protocol from the Crazyradio which is used on the Crazyflie quadcopter. The Crazyradio is a 2.4 GHz radio transceiver dongle that uses the nRF24 chip. It is designed to be used with the Crazyflie quadcopter.

By using a Python script to make the Crazyradio constantly transmit, and then by using GNU Radio, Arnuad was able to sniff and demodulate the GFSK signal from the nRF24 based Crazyradio and pipe the demodulated signal into a nRF24 decoder
