Native Protobuf Encoding
Uses official Meshtastic Protocol Buffer definitions—the same format devices use internally. No custom formats, no compatibility issues.
The Right Way to Send Meshtastic Messages via MQTT
Unlike JSON-based implementations that require special gateway configuration, Meshtastic MQTT Protobuf CLI uses the native Protocol Buffer format that all Meshtastic devices natively support. Universal compatibility, official protocol, future-proof design.
Built on the Official Protocol
Universal Compatibility
Works with any standard Meshtastic gateway without special configuration. No JSON plugin required, no gateway modifications needed.
YAML Configuration
Store connection settings in a YAML configuration file for easy reuse. Set defaults once, override when needed via command-line.
Broadcast & Direct Messaging
Send messages to all nodes or target specific recipients. Full control over message routing and delivery.
Acknowledgment Requests
Request message acknowledgments to confirm delivery. Know when your critical messages reach their destination.
Hop Limit Control
Control message propagation distance with configurable hop limits. Optimize for local or network-wide delivery.
Efficient Binary Format
Protocol Buffers are more compact than JSON, reducing bandwidth usage and improving performance on constrained networks.
Type-Safe Protocol
Protocol Buffers provide strong typing and validation, preventing malformed messages and ensuring protocol compliance.
Command-Line Flexibility
Override any configuration setting via command-line arguments. Perfect for scripts, automation, and one-off commands.
Verbose Debugging
Enable detailed logging to troubleshoot connection issues, verify message encoding, and understand protocol behavior.
Future-Proof Design
Automatically compatible with new protocol features as they're added to Meshtastic. No tool updates required for protocol changes.
