49 * @details The Glucose Service exposes glucose and other data related to a personal glucose
50 * sensor for consumer healthcare applications and is not designed for clinical use.
51 * This module implements the Glucose Service with Glucose Measurement, Glucose Measurement
52 * Context, Glucose Feature and Record Access Control Point characteristics.
53 *
54 * After \ref gls_init_t variable is intialized, the application must call \ref gls_service_init()
55 * to add Glucose Service and Glucose Measurement, Glucose Measurement Context, Glucose
56 * Feature and Record Access Control Point characteristics to the BLE Stack database
57 * according to \ref gls_init_t.char_mask.
