Scene Client

The Scene Client model remotely controls the state of a Scene Server model.

Unlike the Scene Server model, the Scene Client only creates a single model instance in the mesh composition data. The Scene Client can send messages to both the Scene Server and the Scene Setup Server, as long as it has the right application keys.

API for the Scene Client model.

Defines

BT_MESH_MODEL_SCENE_CLI(_cli)

Scene Client model composition data entry.

Parameters

Functions

int bt_mesh_scene_cli_get(struct bt_mesh_scene_cli *cli, struct bt_mesh_msg_ctx *ctx, struct bt_mesh_scene_state *rsp)

Get the current state of a Scene Server.

This call is blocking if the rsp buffer is non-NULL. The response will always be passed to the bt_mesh_scene_cli::status callback.

Parameters

  • cli – [in] Scene client model.

  • ctx – [in] Message context to send with, or NULL to use the configured publication parameters.

  • rsp – [out] Response buffer, or NULL to keep from blocking.

Returns 0

Successfully got the scene state.

Returns -EALREADY

A blocking request is already in progress.

Returns -EADDRNOTAVAIL

A message context was not provided and publishing is not configured.

Returns -EAGAIN

The device has not been provisioned.

Returns -ETIMEDOUT

The request timed out without a response.

int bt_mesh_scene_cli_register_get(struct bt_mesh_scene_cli *cli, struct bt_mesh_msg_ctx *ctx, struct bt_mesh_scene_register *rsp)

Get the full scene register of a Scene Server.

This call is blocking if the rsp buffer is non-NULL. The response will always be passed to the bt_mesh_scene_cli::scene_register callback.

Parameters

  • cli – [in] Scene client model.

  • ctx – [in] Message context to send with, or NULL to use the configured publication parameters.

  • rsp – [out] Response buffer, or NULL to keep from blocking. If the rsp.scenes parameter points to a valid buffer, it will be filled with at most rsp.count number of scenes, and rsp.count will be changed to reflect the number of retrieved scenes.

Returns 0

Successfully got the scene register.

Returns -EALREADY

A blocking request is already in progress.

Returns -EADDRNOTAVAIL

A message context was not provided and publishing is not configured.

Returns -EAGAIN

The device has not been provisioned.

Returns -ETIMEDOUT

The request timed out without a response.

int bt_mesh_scene_cli_store(struct bt_mesh_scene_cli *cli, struct bt_mesh_msg_ctx *ctx, uint16_t scene, struct bt_mesh_scene_register *rsp)

Store the current state as a scene.

This call is blocking if the rsp buffer is non-NULL. The response will always be passed to the bt_mesh_scene_cli::scene_register callback.

Parameters

  • cli – [in] Scene client model.

  • ctx – [in] Message context to send with, or NULL to use the configured publication parameters.

  • scene – [in] Scene number to store. Cannot be BT_MESH_SCENE_NONE.

  • rsp – [out] Response buffer, or NULL to keep from blocking. If the rsp.scenes parameter points to a valid buffer, it will be filled with at most rsp.count number of scenes, and rsp.count will be changed to reflect the number of retrieved scenes.

Returns 0

Successfully sent the store message and processed the response.

Returns -EINVAL

Invalid scene number.

Returns -EALREADY

A blocking request is already in progress.

Returns -EADDRNOTAVAIL

A message context was not provided and publishing is not configured.

Returns -EAGAIN

The device has not been provisioned.

Returns -ETIMEDOUT

The request timed out without a response.

int bt_mesh_scene_cli_store_unack(struct bt_mesh_scene_cli *cli, struct bt_mesh_msg_ctx *ctx, uint16_t scene)

Store the current state as a scene without requesting a response.

Parameters

  • cli – [in] Scene client model.

  • ctx – [in] Message context to send with, or NULL to use the configured publication parameters.

  • scene – [in] Scene number to store. Cannot be BT_MESH_SCENE_NONE.

Returns 0

Successfully sent the store message.

Returns -EINVAL

Invalid scene number.

Returns -EADDRNOTAVAIL

A message context was not provided and publishing is not configured.

Returns -EAGAIN

The device has not been provisioned.

int bt_mesh_scene_cli_delete(struct bt_mesh_scene_cli *cli, struct bt_mesh_msg_ctx *ctx, uint16_t scene, struct bt_mesh_scene_register *rsp)

Delete the given scene.

This call is blocking if the rsp buffer is non-NULL. The response will always be passed to the bt_mesh_scene_cli::scene_register callback.

Parameters

  • cli – [in] Scene client model.

  • ctx – [in] Message context to send with, or NULL to use the configured publication parameters.

  • scene – [in] Scene to delete. Cannot be BT_MESH_SCENE_NONE.

  • rsp – [out] Response buffer, or NULL to keep from blocking. If the rsp.scenes parameter points to a valid buffer, it will be filled with at most rsp.count number of scenes, and rsp.count will be changed to reflect the number of retrieved scenes.

Returns 0

Successfully sent the delete message and processed the response.

Returns -EINVAL
