DragonOS Noble: Detecting, Decoding & Decrypting Meshtastic with Meshtastic-Sniffer (hackRF, LoRa)

Hey everyone, sorry it's been a while. Hope you've all been doing well. Picking things back up with a fresh project: meshtastic-sniffer running on DragonOS. Meshtastic-Sniffer is a standalone C decoder for the Meshtastic LoRa network. One binary, polyphase channelizer built in, no GNU Radio runtime required. With a wide-enough SDR it covers every channel slot across the US band (902-928 MHz, 104 LongFast slots), simultaneously. Big credit up front to Josh Conway (crankylinuxuser on GitLab), whose meshtastic_sdr project a year back was the first practical SDR approach to Meshtastic. Different shape, same family of problem. In this video: brief history, live clone + build on DragonOS, first run with a HackRF, an honest look at HackRF bandwidth limits, what to look out for on the RF side, and what's coming next.
