+ * @brief Cycling Speed and Cadence Service module.
+ *
+ * @details This module implements the Cycling Speed and Cadence Service. If enabled, notification
+ *          of the Cycling Speead and Candence Measurement is performed when the application
+ *          calls ble_cscs_measurement_send().
+ *
+ *          To use this service, you need to provide the the supported features (@ref BLE_CSCS_FEATURES).
+ *          If you choose to support Wheel revolution data (feature bit @ref BLE_CSCS_FEATURE_WHEEL_REV_BIT), 
+ *          you then need to support the 'setting of cumulative value' operation by the supporting the 
+ *          Speed and Cadence Control Point (@ref ble_sdk_srv_sc_ctrlpt) by setting the @ref BLE_SRV_SC_CTRLPT_CUM_VAL_OP_SUPPORTED
+ *          bit of the ctrplt_supported_functions in the @ref ble_cscs_init_t structure.
+ *          If you want to support the 'start autocalibration' control point feature, you need, after the @ref BLE_SC_CTRLPT_EVT_START_CALIBRATION
+ *          has been received and the auto calibration is finished, to call the @ref ble_sc_ctrlpt_rsp_send to indicate that the operation is finished
+ *          and thus be able to receive new control point operations.
+ *          If you want to support the 'sensor location' related operation, you need to provide a list of supported location in the 
+ *          @ref ble_cscs_init_t structure.
+ *          
+ *
+ * @note The application or the service using this module must propagate BLE stack events to the 
+ *       Cycling Speead and Candence Service module by calling ble_cscs_on_ble_evt() from the 
+ *       from the @ref ble_stack_handler function. This service will forward the event to the @ref ble_sdk_srv_sc_ctrlpt module.
+ *
+ * @note Attention! 
+ *  To maintain compliance with Nordic Semiconductor ASA Bluetooth profile 
+ *  qualification listings, this section of source code must not be modified.
