Built-in Telemetry Types Meshtastic nodes broadcast telemetry data alongside messages. Understanding what each telemetry type reports helps you configure nodes correctly and interpret network monitoring data. Device Metrics Broadcast by all nodes automaticall...

Pre-Deployment Checklist The single most important rule for emergency mesh communications: configure and test your equipment before you need it. A device configured under stress, in the dark, during an emergency will have errors. Do this work now. Hardware Pr...

Monitoring Channel Utilization Channel utilization is the single most important metric for diagnosing a congested Meshtastic network. High channel utilization causes missed messages, failed relays, and poor network performance. What Channel Utilization Measur...

Mesh and Amateur Radio (ARES/RACES) LoRa mesh and traditional amateur radio serve complementary roles in emergency communications. Understanding how they fit together helps you deploy each where it is most effective. What ARES and RACES Are ARES (Amateur Radi...

Meshtastic Python CLI Guide The Meshtastic Python package provides both a command-line interface and a Python library for scripting. It is the primary tool for configuring nodes without the mobile app, backing up configurations, and automating tasks. Installa...

Realistic Range and Coverage Expectations Understanding realistic range helps you plan deployments, set expectations with community members, and know when a link will or won’t work. The numbers below are based on real-world community mesh experience. Direct L...

How LoRa Works LoRa (Long Range) is a proprietary wireless modulation technique developed by Semtech Corporation. It is the physical radio layer that both MeshCore and Meshtastic use to transmit messages over long distances without any infrastructure. The Phy...

LoRa vs LoRaWAN: What’s the Difference? This is one of the most common points of confusion for newcomers. LoRa and LoRaWAN are related but completely different things. MeshCore and Meshtastic use LoRa — not LoRaWAN. Understanding the distinction helps explain ...

What You Need to Get Started Getting on a LoRa mesh network requires minimal hardware and no ongoing costs. This page covers everything you need — and what is optional but recommended. Minimum Requirements To send and receive messages on a LoRa mesh network, ...

First Steps After Getting Hardware You have your device. Here is how to go from unboxed hardware to sending your first message on your local mesh network. Step 1: Find Out What’s in Your Area Before flashing firmware, check whether there is an existing networ...

Full Glossary A–Z A reference guide to terms used in LoRa mesh networking, covering MeshCore, Meshtastic, hardware, radio concepts, and related protocols. Terms are listed alphabetically. A ACK Acknowledgment. A confirmation packet sent by the destinat...

Hardware Overview & Buying Guide Choosing hardware for a LoRa mesh node comes down to three factors: what role the device will play (handheld communicator, portable node, or fixed repeater), what firmware you intend to run (MeshCore or Meshtastic), and your bu...
