|

|
|
* Heart Rate sensor (HRS) profile provides functionalities to upper layer module
|
|
* application. The device using this profile takes the role of Heart Rate sensor.
|
|
*
|
|
* The interface of this role to the Application is:
|
|
* - Enable the profile role (from APP)
|
|
* - Disable the profile role (from APP)
|
|
* - Notify peer device during Heart Rate measurement (from APP)
|
|
* - Indicate measurements performed to peer device (from APP)
|
|
*
|
|
* Profile didn't manages multiple users configuration and storage of offline measurements.
|
|
* This must be handled by application.
|
|
*
|
|
* Heart Rate Profile Sensor. (HRPS): A HRPS (e.g. PC, phone, etc)
|
|
* is the term used by this profile to describe a device that can perform Heart Rate
|
|
* measurement and notify about on-going measurement and indicate final result to a peer
|
|
* BLE device.
