MeshCore vs Meshtastic
Two mesh networks, one choice. Discover the differences.
Both MeshCore and Meshtastic are open-source mesh networking projects that use LoRa technology for off-grid communication. While they share the same goal, their approach is fundamentally different. This guide helps you understand the key differences.
The fundamental difference
The biggest difference lies in how messages travel through the network.
Meshtastic: Flooding
Meshtastic uses "flooding" - every device forwards every message to all neighbors, regardless of whether they need it. This works for small networks but becomes inefficient as the network grows.
Like shouting in a crowd: everyone hears everything, even if it is not meant for them.
MeshCore: Path Discovery
MeshCore uses "path discovery" - it actively finds the optimal route to the recipient. Only devices on that route forward the message, saving battery and bandwidth.
Like GPS navigation: find the best route and only use that path.
Feature comparison
| Feature | MeshCore | Meshtastic |
|---|---|---|
| Routing method | Smart path discovery | Flooding |
| Scalability | Excellent | Limited |
| Battery efficiency | Very efficient | Higher consumption |
| Reliability | High | Moderate |
| Encryption | AES-256 | AES-256 |
| Hardware | ESP32 + LoRa | ESP32 + LoRa |
Same hardware, different firmware
Good news: the same devices work with both systems. Switching is just a matter of flashing different firmware.
Heltec V3
LilyGO T-Beam
LilyGO T-Echo
RAK WisBlock
All popular Meshtastic devices can run MeshCore firmware.
Why choose MeshCore?
Better reliability
Smart routing means messages are more likely to reach their destination, even in larger networks.
Scales better
The network stays efficient even with hundreds of devices, where Meshtastic networks may become congested.
Longer battery life
Devices only transmit when necessary, significantly extending battery life.
Future-proof
Active development with continuous improvements to the protocol and features.
