Communicating with the kit

If your application outputs logging information or needs console input, you should connect the kit to your computer to interact with a console. You can use Universal Asynchronous Receiver/Transmitter (UART) for communicating with the kit.

Connecting via UART is quick and power-efficient, but it requires dedicated use of the UART peripheral for logging. Alternatively, you can use an external UART to Universal Serial Bus (USB) bridge. We use the term CDC-UART to refer to UART communication through the UART to USB CDC ACM bridge, to distinguish it from communication through the Nordic UART Service (NUS) over Bluetooth® Low Energy.
