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 Operations Control Point + * is used to stop and start monitoring sessions, among other things. + * + * @note The application must register this module as BLE event observer using the + * NRF_SDH_BLE_OBSERVER macro.
