49 * @details The Body Composition Service (BCS) exposes data related to body composition from a
50 * body composition analyzer (Server) intended for consumer healthcare as well as
51 * sports/fitness applications. This module implements the Body Compositon Service
52 * with the Body Composition Feature and Body Composition Measurement characteristics.
53 *
54 * After \ref bcs_init_t variable is initialized, the application must call \ref bcs_service_init()
55 * to optionally add the Body Compisition Service, Body Composition Meaturement characteristics to
56 * the BLE stack database according to \ref bcs_init_t.char_mask.
