Nordic UART Service implementation.
The Nordic UART Service is a simple GATT-based service with TX and RX characteristics. Data received from the peer is passed to the application, and the data received from the application of this service is sent to the peer as Handle Value Notifications. The service is used by the application to send and receive ASCII text strings to and from the peer.
Raytac modified from Nordic provided NUS reference code to demonstrate the application and verify the throughtput and MTU.
