Detailed Description

Heart Rate Service Client module.

This module contains the APIs and types exposed by the Heart Rate Service Client module. The application can use these APIs and types to perform the discovery of Heart Rate Service at the peer and to interact with it.

Warning
Currently, this module only supports the Heart Rate Measurement characteristic. This means that it is able to enable notification of the characteristic at the peer and is able to receive Heart Rate Measurement notifications from the peer. It does not support the Body Sensor Location and the Heart Rate Control Point characteristics. When a Heart Rate Measurement is received, this module decodes only the Heart Rate Measurement value field (both 8-bit and 16-bit) and provides it to the application.
Note
The application must register this module as the BLE event observer by using the NRF_SDH_BLE_OBSERVER macro. Example:
