About meshcore-dev/MeshCore
MeshCore is a lightweight, portable C++ library that enables multi-hop packet routing for embedded projects using LoRa and other packet radios. It provides a decentralized, self-healing mesh network without requiring internet or central servers. Key features include configurable hop limits, fixed node roles to prevent adverse routing, low power consumption, and support for hardware from Heltec, RAK Wireless, and others. Suitable for off-grid communication, emergency response, outdoor activities, tactical applications, and IoT sensor networks.
