+ * @brief         This function is called to start BLE advertising with the corresponding data
+ *                and parameters while BLE Mesh is working at the same time.
+ *
+ * @note          1. When this function is called, the BLE advertising packet will be posted to
+ *                the BLE mesh adv queue in the mesh stack and waited to be sent.
+ *                2. In the BLE advertising parameters, the "duration" means the time used for
+ *                sending the BLE advertising packet each time, it shall not be smaller than the
+ *                advertising interval. When the packet is sent successfully, it will be posted
+ *                to the adv queue again after the "period" time if the "count" is bigger than 0.
+ *                The "count" means how many durations the packet will be sent after it is sent
+ *                successfully for the first time. And if the "count" is set to 0xFFFF, which
+ *                means the packet will be sent infinitely.
+ *                3. The "priority" means the priority of BLE advertising packet compared with
+ *                BLE Mesh packets. Currently two options (i.e. low/high) are provided. If the
+ *                "priority" is high, the BLE advertising packet will be posted to the front of
+ *                adv queue. Otherwise it will be posted to the back of adv queue.
+ *
+ * @param[in]     param: Pointer to the BLE advertising parameters
+ * @param[in]     data:  Pointer to the BLE advertising data and scan response data
+ *
+ * @return        ESP_OK on success or error code otherwise.
