The Bluetooth Mesh Core API provides functionality for managing the general

|
|
|
|
Bluetooth Mesh state.

Low Power Node

|
|
The Low Power Node (LPN) role allows battery powered devices to participate in
|
|
|
|
|
a mesh network as a leaf node. An LPN interacts with the mesh network through
|
|
|
|
|
a Friend node, which is responsible for relaying any messages directed to the
|
|
|
|
|
LPN. The LPN saves power by keeping its radio turned off, and only wakes up to
|
|
|
|
|
either send messages or poll the Friend node for any incoming messages.
|
|
|
|
|
|
|
|
|
|
The radio control and polling is managed automatically by the mesh stack, but
|
|
|
|
|
the LPN API allows the application to trigger the polling at any time through
|

|
|
|
:c:func:`bt_mesh_lpn_poll`. The LPN operation parameters, including poll
|

|
|
|
interval, poll event timing and Friend requirements is controlled through the
|
|
|
|
|
:option:`CONFIG_BT_MESH_LOW_POWER` option and related configuration options.
