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