10This sample demonstrates the usage of the NUS service (Nordic UART Service) as a serial
11endpoint to exchange data. In this case, the sample assumes the data is UTF-8 encoded,
12but it may be binary data. Once the user connects to the device and subscribes to the TX
13characteristic, it will start receiving periodic notifications with "Hello World!\n".
