Detailed Description

Continuous Glucose Monitoring Service (CGMS) module.

This module implements a sensor for the Continuous Glucose Monitoring Service. The sensor is a GATT Server that sends CGM measurements to a connected CGMS Collector. The CGMS sensor stores records that can be accessed with the Record Access Control Point (RACP). The collector can access the features and status of the sensor. Session Run Time and Session Start Time can be used to convey timing information between the sensor and the collector. The Specific Ops Control Point is used to stop and start monitoring sessions, among other things.
