+ * @param low_interval : true - Increase BLE connection priority to be higher than WiFi's when BLE 
+*                               connection interval is less or equal than 50 ms. The default value 
+*                               is false.
+ *                       false - not increace
+ * @param high_interval : true - Increase BLE connection priority to be higher than WiFi's when BLE 
+*                                connection interval is more than 50 ms. The default value is true.
