Using LabVIEW and LoRa for Long-Distance Status and Control
summary
A working LabVIEW proof of concept talks to Meshtastic-flashed LoRa nodes over a USB serial port using the Meshtastic CLI so central commands toggle LEDs and read switches, but roundtrips take about 10 second roundtrips with the CLI and could drop below one second using protobufs. Typical urban range is about 1 km typical urban range (3–4 km from rooftops; world record 1,336 km). Out‑of‑box batteries last ~a day unless deep‑sleeped for weeks/months; default channel is effectively public but other channels use channel keys for encryption. Connections are fragile in dense, simultaneous-use situations.
