ripplebiz/MeshCore
FreeA new lightweight, hybrid routing mesh protocol for packet radios
About ripplebiz/MeshCore
MeshCore is a lightweight, portable C++ library designed for developers building resilient, decentralized communication networks using LoRa and other packet radios. It enables multi-hop packet routing where devices can relay messages across intermediate nodes, extending range far beyond a single radio's reach. Unlike more casual-focused solutions like Meshtastic or advanced networking stacks like Reticulum, MeshCore balances simplicity with scalability, making it ideal for custom embedded projects. Key capabilities include configurable hop limits, fixed node roles (e.g., 'Companion' nodes that do not repeat messages to prevent adverse routing), support for popular LoRa hardware from Heltec and RAK Wireless, low power consumption for battery/solar operation, and pre-built example applications for easy deployment without manual firmware compilation. It operates without any central server or internet, creating self-healing mesh networks suitable for off-grid, emergency, tactical, and IoT applications.
Key Features
Pros & Cons
- Lightweight and portable C++ library suitable for embedded projects
- Multi-hop routing extends communication range beyond a single radio
- Decentralized and self-healing network infrastructure
- Low power consumption enables long-term battery/solar operation
- Easy to deploy with pre-built example applications and serial console interaction
- Limited to LoRa and similar packet radio hardware
- Requires familiarity with embedded development and firmware flashing
- No built-in graphical user interface; interaction is via serial console
- Less feature-rich than turnkey consumer solutions like Meshtastic or advanced networking stacks like Reticulum
