Private Beacon Client
The Private Beacon Client model is a foundation model defined by the Bluetooth
mesh specification. It is enabled with the
CONFIG_BT_MESH_PRIV_BEACON_CLI option.
The Private Beacon Client model is introduced in the Bluetooth Mesh Protocol Specification version 1.1, and provides functionality for configuring the Private Beacon Server models.
The Private Beacons feature adds privacy to the different Bluetooth Mesh beacons by periodically randomizing the beacon input data. This protects the mesh node from being tracked by devices outside the mesh network, and hides the network’s IV index, IV update and the Key Refresh state.
The Private Beacon Client model communicates with a Private Beacon Server model using the device key of the target node. The Private Beacon Client model may communicate with servers on other nodes or self-configure through the local Private Beacon Server model.
All configuration functions in the Private Beacon Client API have net_idx
and addr as their first parameters. These should be set to the network
index and the primary unicast address the target node was provisioned with.
If present, the Private Beacon Client model must only be instantiated on the primary element.
