This guide covers systematic diagnosis of common Meshtastic network issues: nodes that can't hear each other, poor range, network congestion, and routing failures. Diagnostic framework Work from the bottom up: radio layer first, then routing, then application...

A deployed repeater requires periodic attention to maintain performance. This page covers the key maintenance tasks and performance metrics for Meshtastic Router/Repeater nodes. Key performance indicators MetricHealthy rangeAction if outside range Node upt...

Choosing the wrong connector is one of the most common causes of installation failure and wasted money. LoRa devices and antennas use several different RF connector types, and they are not all interchangeable. The critical SMA vs. RP-SMA distinction SMA and R...

Operating LoRa mesh equipment in the United States requires compliance with FCC Part 15 rules. This page summarizes the relevant regulations and explains how to calculate whether your installation is within limits. Disclaimer: This page is a general referenc...

MeshCore encrypts all message payloads using AES-256-CTR. Understanding how this works helps you make informed decisions about what to transmit over the mesh and how to configure private channels. What is encrypted All direct messages (DMs): Encrypted end-...

MeshCore is an open-source project with a distributed community and a governance structure that changed significantly in April 2026. Understanding the project landscape helps you navigate firmware choices and community resources. The April 2026 governance spl...

A systematic approach to diagnosing MeshCore repeater issues. Work from the physical layer up: radio first, then configuration, then network behavior. Quick pre-diagnosis checklist Is the device powered? (check LED, screen, or measure supply voltage) Is ...

When a MeshCore repeater becomes unreachable, misconfigured, or boot-loops, reflashing is the recovery option. This page covers reflash procedures for all common device families. When to reflash vs. when to reconfigure SymptomTry firstIf that fails Node wo...

A link budget calculation estimates whether a radio path between two nodes will work reliably before you deploy hardware. It’s the single most useful tool for avoiding wasted installation trips and surprised failures. The link budget equation Received Power (...

Several free tools can help you model coverage and plan repeater placement before deploying hardware. Using these tools can save wasted trips and help you choose between candidate sites. HeyWhatsThat (heywhatsthat.com) The fastest tool for estimating radio ho...

When buying LoRa hardware, listings frequently mention specific radio chip models. Understanding what these chips are and how they differ prevents costly purchasing mistakes. Why the chip matters The LoRa transceiver chip is the core radio hardware. It determ...

Many Meshtastic users don't realize a full web-based interface is available in addition to the mobile app. The web interface provides additional tools for configuration and administration that aren't available in the app. The Meshtastic web app (app.meshtasti...
