 * @brief Blood Pressure Profile Sensor
 *
 * Blood pressure sensor (BPS) profile provides functionalities to upper layer module
 * application. The device using this profile takes the role of Blood pressure 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 Blood Pressure 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.
 *
 * Blood Pressure Profile Sensor. (BLPS): A BLPS (e.g. PC, phone, etc)
 * is the term used by this profile to describe a device that can perform blood pressure
 * measurement and notify about on-going measurement and indicate final result to a peer
 * BLE device.
