Profile – application interface functions

6.1

Heart rate profile

6.1.1

HRProfile_Init()

Description

The application calls this function to initialize the heart rate profile. The initialization

procedure returns BLE_STATUS_SUCCESS if started successfully or

BLE_STATUS_FAILED if not. On successful initialization of the profile, the application is

notified through the event EVT_HRS_INITIALIZED through the registered callback.

Parameters

• Feature support flag: the characteristic/feature mask supported by the heart rate profile

during initialization. The various characteristics mask supported by the profile are:

BODY_SENSOR_LOCATION_SUPPORT_MASK

(0x01)

ENERGY_EXTENDED_INFO_SUPPORT_MASK

(0x02)

• BLE_CALLBACK_FUNCTION_TYPE: the callback function to be registered by the heart

rate profile for notification/communication to the main BLE profile.

• Sensor location value: the Value for the body sensor location.

6.1.2

HR_Sensor_Make_Discoverable()

Description

This command puts the device into discoverable mode. BLE_STATUS_SUCCESS is

returned if the command to put the device into discoverable mode was issued successfully.

Parameters

• useBoundedDeviceList: set this flag to TRUE '1' if Profile needs to advertise to devices

already bonded; otherwise, set it to FALSE '0'.
