ESP32 BLE Arduino And getting a compile error of 'ringbuf_type_t' has not been declared

Question

when i install Arduino IDE and install all the library carefully after that i install ESP32 BLE Arduino library successfully and click on file< Example< ESP32 BLE Arduino < BLE_notify add the code and select a board ESP32 dev module and compile the this through Compiler error
