49 * @details The Running Speed and Cadence (RSC) Service exposes speed, cadence and other data related to
50 * fitness applications such as the stride length and the total distance the user has traveled
51 * while using the Running Speed and Cadence sensor (Server). This module implements the Running
52 * Speed and Cadence Service with RSC Measurement, RSC Feature, Sensor Location and SC Control
53 * Point characteristics.
54 *
55 * After \ref rscs_init_t variable is initialized, the application must call \ref rscs_service_init()
56 * to add the Running Speed and Cadence Service and RSC Measurement, RSC Feature, Sensor Location and
57 * SC Control Point characteristics to the BLE Stack database according to \ref rscs_init_t.char_mask.
