| ######## |
| |
| 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 |
| :cpp: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. |
