meshtastic
A scratch workspace for listening to Meshtastic's LoRa mesh with a HackRF instead of a Meshtastic radio. One GNU Radio flowgraph tunes to 906.875 MHz at 2 Msps, filters and decimates to 250 kHz, and feeds both a waterfall and a LoRa receiver at spreading factor 9; a second script draws the waterfall alone. The decoding is the open-source gr-lora_sdr module, cloned in beside the HackRF tools. A few days in November 2025, no notes, an empty log, and nothing to say a packet was ever decoded.
