 *
 * The BLPC is responsible for providing Blood Pressure Profile Collector functionalities
 * to upper layer module or application. The device using this profile takes the role
 * of Blood Pressure Profile Collector.
 *
 * Blood Pressure Profile Collector. (BLPC): A BLPC (e.g. PC, phone, etc)
 * is the term used by this profile to describe a device that can interpret blood pressure
 * measurement in a way suitable to the user application.
