The Cellular Monitor app lets you also play back and view modem traces captured in SEGGER Real Time Transfer (RTT) logger.
Note
In the current release of the Cellular Monitor app, the RTT interface is not supported for traces capture. You can only view RTT modem traces captured outside of the tool.
To view RTT modem traces in Cellular Monitor, complete the following steps:
- Enable the RTT trace backend for your application. The exact steps are beyond the scope of the app documentation. For example, if you have an application based on the nRF Connect SDK, you can use a dedicated snippet.
- Ensure your device is running supported modem firmware. See Minimum requirements and limitations, and note the version for playback.
- Use the J-Link RTT logger to collect the trace or traces and save in binary (
.bin) format. See SEGGER Real Time Transfer (RTT) for more information. - Load and play back the trace in Cellular Monitor. See Loading modem traces for playback for more information.
