Meshtastic

Protobuf message definitions for a mesh radio network, documented with API reference and prebuilt TypeScript, Rust and cross-language client packages for app and firmware integration.

Fully-featured MQTT 5.0 client with complete packet/property support, QoS 0–2 state machine, TLS/WebSocket transports, asynchronous APIs with reactive message streams, immutable payloads, minimal dependencies and spec validation.

Connects to Meshtastic mesh radios via BLE, TCP or USB, handling handshake, NodeDB, ACKs, decryption and retries; exposes async streams and type-safe events for apps and gateways.

Converts Cursor-on-Target XML into TAKPacketV2 protobufs, compresses with zstd using dual dictionaries for LoRa, sanitizes mesh XML, and encodes compact structured payloads with delta geometry.

Pure zero-runtime-dependency Zstandard codec producing standard zstd frames with dictionary support; immutable digested dictionaries reusable across threads, one-shot API, and decompression-bomb guard.
