Connecting via RTT

Getting started with nRF5 SDK and Keil (nRF51 & nRF52 Series)

To communicate via Real Time Transfer (RTT), connect your development kit via Universal Serial Bus (USB) and run the J-Link RTT Viewer.

The J-Link RTT Viewer is installed as part of the nRF Command Line Tools.

To run the J-Link RTT Viewer on Windows, complete the following steps:

  1. Select the correct target device.
    The target device is represented by the ID of your development kit.
  2. Select SWD as the target interface.
