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. LoRa Mesh vs. CB Radio LoRa Mesh...

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...

Do I need a license to use LoRa mesh? No license is required. Both MeshCore and Meshtastic operate on the 915 MHz ISM (Industrial, Scientific, and Medical) band in the US and Canada. ISM bands are unlicensed — anyone can use compliant equipment without registr...

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 (i...

A MeshCore room server turns a Raspberry Pi, VPS, or any Linux server into a mesh infrastructure node that provides message persistence, node discovery, and optionally internet bridging to your mesh network. What a room server provides Message persistence:...

A single room server can host multiple rooms (channels), each with independent access control and settings. This is common for community networks that run both a public room and a private emergency operations room. Room architecture In MeshCore, a “room” is a...

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 ...

Room servers with internet connectivity can bridge LoRa mesh traffic to internet-connected clients, enabling phone users without LoRa hardware to participate in the mesh network. MQTT integration allows mesh traffic to be monitored and analyzed with standard t...

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 puts your nodes on meshmap.net. How MQTT works in...

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...
