Protobufs

Overview​

Protocol BuffersProtobuf (Protocol Buffers). A method developed by Google for serializing structured data, used in Meshtastic for efficient communication protocol between devices., commonly referred to as ProtobufsProtobuf (Protocol Buffers). A method developed by Google for serializing structured data, used in Meshtastic for efficient communication protocol between devices., are a language-neutral, platform-neutral, extensible mechanism for serializing structured data. They are used by Meshtastic software for encoding and transmitting data between the App and Device, as well as for Device-to-Device communication.

ProtobufsProtobuf (Protocol Buffers). A method developed by Google for serializing structured data, used in Meshtastic for efficient communication protocol between devices. provide an efficient and lightweight way of exchanging data, making them well-suited for use in resource-constrained environments like the Meshtastic network. They offer several advantages over traditional data formats like XML or JSON, including:

  • Smaller serialized size: ProtobufProtobuf (Protocol Buffers). A method developed by Google for serializing structured data, used in Meshtastic for efficient communication protocol between devices. serialized data is typically much smaller than XML or JSON representations of the same data.
  • Faster serialization and deserialization: ProtobufsProtobuf (Protocol Buffers). A method developed by Google for serializing structured data, used in Meshtastic for efficient communication protocol between devices. are designed to be serialized and deserialized quickly, which is important for applications that need to process large amounts of data.
  • Type-safe and self-describing: ProtobufProtobuf (Protocol Buffers). A method developed by Google for serializing structured data, used in Meshtastic for efficient communication protocol between devices. messages are type-safe, and the message formats are self-describing, making it easier to work with and maintain the data over time.

Meshtastic Protobufs​

The Meshtastic project defines its own set of ProtobufProtobuf (Protocol Buffers). A method developed by Google for serializing structured data, used in Meshtastic for efficient communication protocol between devices. messages for various types of data exchanged between app-device and device-device. These messages are organized into different modules.

The official documentation for the Meshtastic ProtobufProtobuf (Protocol Buffers). A method developed by Google for serializing structured data, used in Meshtastic for efficient communication protocol between devices. messages can be found on the Buf Schema Registry (BSR). The BSR provides a centralized location for managing and documenting the ProtobufProtobuf (Protocol Buffers). A method developed by Google for serializing structured data, used in Meshtastic for efficient communication protocol between devices. schemas used by the project.
