Health Client

The Health Client model interacts with a Health Server model to read out diagnostics and control the node’s attention state.

All message passing functions in the Health Client API have cli as their first parameter. This is a pointer to the client model instance to be used in this function call. The second parameter is the ctx or message context. Message context contains netkey index, appkey index and unicast address that the target node uses.

The Health Client model is optional, and may be instantiated on any element. However, if a Health Client model is instantiated on an element other than the primary, an instance must also be present on the primary element.

See Health faults for a list of specification defined fault values.

Functions

int bt_mesh_health_cli_fault_get(struct bt_mesh_health_cli *cli, struct bt_mesh_msg_ctx *ctx, uint16_t cid, uint8_t *test_id, uint8_t *faults, size_t *fault_count)

Get the registered fault state for the given Company ID.

This method can be used asynchronously by setting test_id and ( faults or fault_count ) as NULL This way the method will not wait for response and will return immediately after sending the command.

To process the response arguments of an async method, register the fault_status callback in bt_mesh_health_cli struct.

int bt_mesh_health_cli_period_get(struct bt_mesh_health_cli *cli, struct bt_mesh_msg_ctx *ctx, uint8_t *divisor)

Get the target node’s Health fast period divisor.

The health period divisor is used to increase the publish rate when a fault is registered. Normally, the Health server will publish with the period in the configured publish parameters. When a fault is registered, the publish period is divided by (1 << divisor). For example, if the target node’s Health server is configured to publish with a period of 16 seconds, and the Health fast period divisor is 5, the Health server will publish with an interval of 500 ms when a fault is registered.

This method can be used asynchronously by setting divisor as NULL. This way the method will not wait for response and will return immediately after sending the command.

To process the response arguments of an async method, register the period_status callback in bt_mesh_health_cli struct.

Parameters:
  • cli – Client model to send on.

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

  • divisor – Health period divisor response buffer.

Returns:

0 on success, or (negative) error code on failure.

int bt_mesh_health_cli_period_set(struct bt_mesh_health_cli *cli, struct bt_mesh_msg_ctx *ctx, uint8_t divisor, uint8_t *updated_divisor)

The health period divisor is used to increase the publish rate when a fault is registered. Normally, the Health server will publish with the period in the configured publish parameters. When a fault is registered, the publish period is divided by (1 << divisor). For example, if the target node’s Health server is configured to publish with a period of 16 seconds, and the Health fast period divisor is 5, the Health server will publish with an interval of 500 ms when a fault is registered.

This method can be used asynchronously by setting updated_divisor as NULL. This way the method will not wait for response and will return immediately after sending the command.
