Generic Property Client

The Generic Property Client model can access properties from a Property Server remotely. The Property Client can talk directly to all types of Property Servers, but only if it shares an application key with the target server.

Generally, the Property Client should only target User Property Servers, unless it is part of a network administrator node that is responsible for configuring the other mesh nodes.

To ease the configuration, the Property Client can be paired with a Client Property Server that lists which properties this Property Client will request.

BT_MESH_MODEL_PROP_CLI(_cli)

Generic Property Client model composition data entry.

Parameters

Functions

int bt_mesh_prop_cli_client_props_get(struct bt_mesh_prop_cli *cli, struct bt_mesh_msg_ctx *ctx, uint16_t id, struct bt_mesh_prop_list *rsp)

Get the list of Generic Client Properties of the bound server.

To get the list of other property states, use :ref:bt_mesh_prop_cli_props_get.

This call is blocking if the rsp buffer is non-NULL. Otherwise, this function will return, and the response will be passed to the bt_mesh_prop_cli::prop_list callback.

Parameters

  • cli – [in] Client model to send on.

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

  • id – [in] A starting Client Property ID present within an element.

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

Return values

  • 0 – Successfully sent the message and populated the rsp buffer.

  • -EINVAL – The rsp::ids list was NULL.

  • -ENOBUFS – The client received a response, but the supplied response buffer was too small to hold all the properties. All property IDs that could fit in the response buffers were copied into it, and the rsp::count field was left unchanged.

  • -EALREADY – A blocking request is already in progress.

  • -ENOTSUP – A message context was not provided and publishing is not supported.

  • -EADDRNOTAVAIL – A message context was not provided and publishing is not configured.

  • -EAGAIN – The device has not been provisioned.

  • -ETIMEDOUT – The request timed out without a response.

int bt_mesh_prop_cli_props_get(struct bt_mesh_prop_cli *cli, struct bt_mesh_msg_ctx *ctx, enum bt_mesh_prop_srv_kind kind, struct bt_mesh_prop_list *rsp)

Get the list of properties of the bound server.

This call is blocking if the rsp buffer is non-NULL. Otherwise, this function will return, and the response will be passed to the bt_mesh_prop_cli::prop_list callback.

Parameters

  • cli – [in] Client model to send on.

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

  • kind – [in] Kind of Property Server to query. Use with every property kind except for BT_MESH_PROP_SRV_KIND_CLIENT. To get the list of client property states, use :ref:bt_mesh_prop_cli_client_props_get.

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

Return values

  • 0 – Successfully sent the message and populated the rsp buffer.

  • -EINVAL – The rsp::ids list was NULL.

  • -ENOBUFS – The client received a response, but the supplied response buffer was too small to hold all the properties. All property IDs that could fit in the response buffers were copied into it, and the rsp::count field was left unchanged.
