Detailed Description

Pre-configured Operational Dataset TLVs for initializing the Thread network.

This module provides static definitions for the OpenThread Operational Dataset using the Type-Length-Value (TLV) format. This dataset includes critical network parameters required for a device to attach to or form a specific Thread network. Dataset Components: The binary blob otapp_dataset_tlv typically contains:

• Active Timestamp: Timestamp of the dataset generation.
• Channel: The IEEE 802.15.4 channel to operate on.
• PAN ID: Personal Area Network Identifier.
• Network Key (Master Key): 16-byte key for encryption.
• Network Name: Human-readable string identifying the network.
• Extended PAN ID: 64-bit unique identifier.
• Mesh-Local Prefix: IPv6 prefix for mesh-local addresses. Usage: This constant is used by otapp_setDataset_tlv during the initialization phase (otapp_network_init) to provision the OpenThread stack if no dataset is currently active.

Default Operational Dataset encoded as TLV byte array.

This structure holds the serialized dataset that defines the network credentials. It is applied to the OpenThread stack via otDatasetSetActiveTlvs(). Contents:

• .mTlvs: The raw byte array containing the TLV sequence.
• .mLength: The total length of the valid data in the byte array (111 bytes).

  Note

  This dataset corresponds to a specific pre-defined network configuration. Changing these bytes will change the network the device attempts to join.
