LoRa mesh networks provide a compelling platform for IoT sensor deployments, especially where WiFi doesn't reach, cellular is too expensive, and wired connections are impractical. When LoRa mesh is the right choice for IoT ScenarioLoRa mesh advantage Remot...

A practical guide for deploying LoRa mesh sensor nodes in the field for environmental monitoring, agriculture, and infrastructure monitoring. Example use cases from the community Weather station network Multiple BME280-equipped nodes reporting temperature, h...

LoRa mesh occupies a specific niche in the communications landscape. Understanding what it does and doesn't do well helps you choose the right tool for each situation - and make the case for mesh to others in your community. Cost, subscription, and range figu...

Both MeshCore and Meshtastic are free, open-source LoRa mesh networking platforms. They use different routing architectures and have different community ecosystems. Understanding the differences helps you choose - or know when to run both. Protocol comparison...

My device won't show up in the app. What do I check? Is Bluetooth enabled? The app connects via BLE. Ensure Bluetooth is on in your phone settings and the app has Bluetooth permission. Is the device powered and running? Check for activity LED or screen (if ...

A MeshCore room server is a single node that hosts a single room. There is no multi-room mode: one room server node = one room. To offer several separate spaces across a community (for example, a public room and a private emergency operations room), you deploy...

A reference for terminology used throughout this wiki and in the mesh networking community. A Advertisement (advert) A packet broadcast by a MeshCore node to announce its existence on the network. Advertisements contain the node's identity, position (if co...

A MeshCore room server runs as firmware on a single LoRa node (typically nRF52840 or ESP32 hardware). It is a store-and-forward node on the RF mesh and does not have a native internet, TCP, or MQTT bridge. There is no MeshCore feature that lets phone users wit...

MQTT lets a Meshtastic node forward all mesh traffic to the internet, making your local mesh visible on the network map, bridging messages to internet clients, and enabling monitoring and logging. This is what feeds online community maps (e.g. via the MapRepor...

A Meshtastic internet gateway bridges local LoRa radio traffic to the internet and can serve as a powerful community infrastructure node. This guide covers setting up a dedicated gateway on a Raspberry Pi. Gateway hardware options OptionHardwareProsCons ES...

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...
