Room Server Setup & Configuration Step 1 — Flash Room Server Firmware Use the MeshCore web flasher at flasher.meshcore.io. Select your hardware (e.g., Heltec V3) and choose the Room Server firmware variant. Step 2 — Connect via Serial or Bluetooth Connect vi...

Dual Deployment: Separate Repeater and Room Server The recommended best practice for any fixed site is to deploy two separate devices rather than enabling repeat mode on the room server. Why Two Devices? A repeater and a room server have conflicting placement...

Meshtastic MQTT Gateway Overview MQTT allows Meshtastic nodes to bridge the local LoRa mesh to the internet, enabling mesh messages to travel between physically separated mesh islands and feeding data into monitoring dashboards. Hardware Requirements Only ESP...

Home Assistant & Grafana Integration Once your Meshtastic node is publishing to an MQTT broker, that data stream can feed home automation and monitoring platforms. Home Assistant Integration Home Assistant has a built-in MQTT integration that can subscribe to...

Coverage Planning Tools Overview Before deploying hardware, use these tools to estimate coverage, find line-of-sight paths, and identify gaps in your network. Most are free and browser-based. MeshCore-Specific Tools ToolURLWhat It Does NoDakM...

MeshMapper Wardriving Guide MeshMapper is a platform for mapping actual measured RF coverage of a MeshCore network — not just node locations, but real signal coverage at road level. This is the ground truth that theoretical planners cannot provide. Getting th...

Path Discovery and Route Learning MeshCore uses an intelligent path discovery system rather than simple flooding. This design means the network gets quieter — not louder — as usage increases. How Path Discovery Works: Step by Step First message to an unkno...

Path Hash Modes (MeshCore) Path hash modes control how repeaters identify themselves in routing path headers within MeshCore packets. This feature is available in MeshCore firmware v1.14.0+ and requires companion app v1.41.0+. Mode Comparison ModeBytes per...

Why MeshCore Scales Better Than Flooding Understanding the difference between MeshCore’s path-discovery routing and Meshtastic’s flood routing explains why the two protocols behave very differently in large networks. Flood Routing (Meshtastic) Every relay ...

Regional Scoping with ISO Codes (MeshCore) Regional scoping is part of the RegionMesh system for applying ISO 3166-2 geographic identifiers to MeshCore repeaters. It allows repeaters to filter message routing by region, reducing cross-country network congestio...
