DragonOS Noble Receive and Decode Meshtastic w/ SDR (hackRF, GNU Radio)
The setup’s super simple: DragonOS, ...Meshtastic_SDR, a HackRF, and a couple of Python packages. That’s all it takes to start receiving and decoding messages. Nothing fancy, just a clean “get it running” demo.
What is Meshtastic?
It’s an open-source project that uses LoRa radios to create long-range, off-grid mesh networks. Normally, a single radio listens on just one channel — but with an SDR like the HackRF, you can monitor all channels at once across whatever frequency range your SDR supports.
A quick note: Jeff Geerling put out a fantastic video diving into Meshtastic_SDR in detail. In his demo, decodes didn’t happen during the recording — but after I went back and took another look on my end, I was getting successful decodes. So consider this video more of a quick-start companion piece to his deeper dive.
