Detailed Description

Blood Pressure Service module.

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 SoftDevice Event Handler function.

Attention! To maintain compliance with Nordic Semiconductor ASA Bluetooth profile qualification listings, this section of source code must not be modified.

Enumeration Type Documentation

enum ble_bps_evt_type_t

Blood Pressure Service event type.

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
	)

Function for initializing the Blood Pressure Service.

Parameters

[out]	p_bps	Blood 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_init	Information needed to initialize the service.

Returns

NRF_SUCCESS on successful initialization of service, otherwise an error code.

uint32_t ble_bps_is_indication_enabled	(	ble_bps_t *	p_bps,
		bool *	p_indication_enabled
	)

Function for checking if indication of Blood Pressure Measurement is currently enabled.

Parameters

[in]	p_bps	Blood Pressure Service structure.
[out]	p_indication_enabled	TRUE if indication is enabled, FALSE otherwise.

Returns

NRF_SUCCESS on success, otherwise an error code.

uint32_t ble_bps_measurement_send	(	ble_bps_t *	p_bps,
		ble_bps_meas_t *	p_bps_meas
	)

Function for sending blood pressure measurement if indication has been enabled.

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_bps	Blood Pressure Service structure.
[in]	p_bps_meas	Pointer to new blood pressure measurement.

Returns

NRF_SUCCESS on success, otherwise an error code.

void ble_bps_on_ble_evt	(	ble_bps_t *	p_bps,
		ble_evt_t *	p_ble_evt
	)

Function for handling the Application's BLE Stack events.

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

Parameters

[in]	p_bps	Blood Pressure Service structure.
[in]	p_ble_evt	Event received from the BLE stack.
