Detailed Description

This module implements the Blood Pressure Service.

     If an event handler is supplied by the application, the Blood Pressure 
     Service will generate Blood Pressure Service events to the application.
Note
The application must propagate BLE stack events to the Blood Pressure Service module by calling ble_bps_on_ble_evt() from the from the BLE Stack Event Handler function.

Enumeration Type Documentation

Enumerator
BLE_BPS_EVT_INDICATION_ENABLED 

Blood Pressure value indication enabled event.

BLE_BPS_EVT_INDICATION_DISABLED 

Blood Pressure value indication disabled event.

BLE_BPS_EVT_INDICATION_CONFIRMED 

Confirmation of a blood pressure measurement indication has been received.

Function Documentation

uint32_t ble_bps_init ( ble_bps_t p_bps,
const ble_bps_init_t p_bps_init 
)
Parameters
[out]p_bpsBlood Pressure Service structure. This structure will have to be supplied by the application. It will be initialized by this function, and will later be used to identify this particular service instance.
[in]p_bps_initInformation needed to initialize the service.
Returns
NRF_SUCCESS on successful initialization of service, otherwise an error code.
void ble_bps_on_ble_evt ( ble_bps_t p_bps,
ble_evt_t p_ble_evt 
)

Handles all events from the BLE stack of interest to the Blood Pressure Service.

Parameters
[in]p_bpsBlood Pressure Service structure.
[in]p_ble_evtEvent received from the BLE stack.
uint32_t ble_bps_measurement_send ( ble_bps_t p_bps,
ble_bps_meas_t p_bps_meas 
)

The application calls this function after having performed a Blood Pressure measurement. If indication has been enabled, the measurement data is encoded and sent to the client.

Parameters
[in]p_bpsBlood Pressure Service structure.
[in]p_bps_measPointer to new blood pressure measurement.
Returns
NRF_SUCCESS on success, otherwise an error code.
uint32_t ble_bps_is_indication_enabled ( ble_bps_t p_bps,
bool *  p_indication_enabled 
)
Parameters
[in]p_bpsBlood Pressure Service structure.
[out]p_indication_enabledTRUE if indication is enabled, FALSE otherwise.
Returns
NRF_SUCCESS on success, otherwise an error code.
