Detailed Description

This module contains the APIs and types exposed by the Running Speed and Cadence Service Client module. These APIs and types can be used by the application to perform discovery of Running Speed and Cadence Service at the peer and interact with it.

Note
The application must register this module as BLE event observer using the NRF_SDH_BLE_OBSERVER macro. Example:

Macro Definition Documentation

Typedef Documentation

typedef void(* ble_rscs_c_evt_handler_t)( ble_rscs_c_t *p_ble_rscs_c, ble_rscs_c_evt_t *p_evt)

Event handler type.

This is the type of the event handler that should be provided by the application of this module in order to receive events.

Enumeration Type Documentation

RSCS Client event type.

Enumerator
BLE_RSCS_C_EVT_DISCOVERY_COMPLETE

Event indicating that the Running Speed and Cadence Service has been discovered at the peer.

BLE_RSCS_C_EVT_RSC_NOTIFICATION

Event indicating that a notification of the Running Speed and Cadence measurement characteristic has been received from the peer.

Function Documentation

uint32_t ble_rscs_c_handles_assign ( ble_rscs_c_t * p_ble_rscs_c ,
uint16_t conn_handle ,
ble_rscs_c_db_t * p_peer_handles
)

Function for assigning handles to a this instance of rscs_c.

Call this function when a link has been established with a peer to associate this link to this instance of the module. This makes it possible to handle several link and associate each link to a particular instance of this module. The connection handle and attribute handles will be provided from the discovery event BLE_RSCS_C_EVT_DISCOVERY_COMPLETE .

Parameters
[in] p_ble_rscs_c Pointer to the RSC client structure instance to associate.
[in] conn_handle Connection handle to associated with the given RSCS Client Instance.
[in] p_peer_handles Attribute handles on the RSCS server that you want this RSCS client to interact with.
uint32_t ble_rscs_c_init ( ble_rscs_c_t * p_ble_rscs_c ,
ble_rscs_c_init_t * p_ble_rscs_c_init
)

Function for initializing the Running Speed and Cadence Service Client module.

This function will initialize the module and set up Database Discovery to discover the Running Speed and Cadence Service. After calling this function, call ble_db_discovery_start to start discovery once a link with a peer has been established.

Parameters
[out] p_ble_rscs_c Pointer to the RSC Service client structure.
[in] p_ble_rscs_c_init Pointer to the RSC Service initialization structure containing the initialization information.
Return values
NRF_SUCCESS Operation success.
NRF_ERROR_NULL A parameter is NULL. Otherwise, an error code returned by ble_db_discovery_evt_register .
void ble_rscs_c_on_ble_evt ( ble_evt_t const * p_ble_evt ,
void * p_context
)

Function for handling the Application's BLE Stack events.

Handles all events from the BLE stack of interest to the Running Speed and Cadence Service client.

Parameters
[in] p_ble_evt Event received from the BLE stack.
[in] p_context Running Speed and Cadence Service client structure.
void ble_rscs_on_db_disc_evt ( ble_rscs_c_t * p_ble_rscs_c ,
ble_db_discovery_evt_t const * p_evt
)

Function for handling events from the database discovery module.

Call this function when getting a callback event from the DB discovery modue. This function will handle an event from the database discovery module, and determine if it relates to the discovery of Running Speed and Cadence service at the peer. If so, it will call the application's event handler indicating that the RSC service has been discovered at the peer. It also populates the event with the service related information before providing it to the application.

Parameters
p_ble_rscs_c Pointer to the Runnind Speed and Cadence Service client structure.
[in] p_evt Pointer to the event received from the database discovery module.
