Hi Peter,

I don't think we have an API or mechanism for this.

Hi Swathy,

I need to make this judgment within the nRF4L15.

Best regards,

Hi Peter,

You can confirm a successful RTT connection by observing output in the J-Link RTT Viewer (e.g., "Hello World!" appearing confirms the connection is live). When using the RTT socket (TCP at 127.0.0.1:19021), a successful connection is confirmed by the J-Link driver printing a blurb like:

SEGGER J-Link V5.02k - Real time terminal output
J-Link OB-SAM3U128-V2-NordicSemi compiled Mar 15 2016

Refer: Debugging with Real Time Terminal

Best Regards,

Swathy
