Choosing and transforming trace output format

The output format can be selected when starting a trace and a binary trace file can be transformed afterwards.

Table 1. Trace output format options
Option Description
--output-raw filename.bin To export as a binary trace file. Raw files are primarily used as an attachment when assistance is needed from Nordic Semiconductor support.
--output-wireshark path_to_wireshark To pipe the output to Wireshark, specify the path to a Wireshark executable.
--output-pcapng out.pcapng To convert the output to a file with pcapng format.
--output-opp config.json For use with Online Power Profiler (OPP).
The following example shows how to transform a binary file raw-file.bin to Packet Capture Next Generation (PcapNG):
