Using SEGGER's J-Link RTT viewer to connect via RTT

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

Note: SEGGER Embedded Studio (SES) natively supports RTT. If enabled, the monitor shows up when you start debugging. Alternatively, you can use SEGGER's J-Link RTT Viewer as described below.

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:

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