 /** NimBLE_Secure_Server Demo:
- *  
+ *
  * This example demonstrates the secure passkey protected conenction and communication between an esp32 server and an esp32 client.
  * Please note that esp32 stores auth info in nvs memory. After a successful connection it is possible that a passkey change will be ineffective.
  * To avoid this clear the memory of the esp32's between security testings. esptool.py is capable of this, example: esptool.py --port /dev/ttyUSB0 erase_flash.
