What is a MeshCore Room Server? A Room Server is a store-and-forward bulletin board that runs directly on a LoRa node running MeshCore firmware. It acts as a shared message board for the mesh community - any node that can reach the room server can post and rea...

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 via USB serial at 115200 baud using a ...

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 A device...

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 NoDakMesh Node P...

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. MeshMapper ...

MeshCore uses a hybrid flood-first / direct-route-after approach rather than persistent flooding. For stable repeat-unicast traffic the network quiets down as paths are learned; under mobility, link churn, or heavy group/broadcast traffic it can get louder aga...

Path Hash Modes (MeshCore) Path hash modes control how repeaters identify themselves in routing path headers within MeshCore packets. This feature is available in recent MeshCore firmware versions. Check your firmware release notes for version-specific availab...

Understanding the difference between MeshCore's flood-first, direct-route-after routing and Meshtastic's flood routing explains why the two protocols behave differently in large networks. Flood Routing (Meshtastic) In a managed flood, each relay rebroadcast...
