Record

First, read the basic usage to compile things.

To record, you use the record tracer.

To send a trace to Eurecom, you run (unless we specifically ask you to activate/deactivate specific traces):

./record -d ../T_messages.txt -o record.raw -ON -off VCD -off HEAVY -off LEGACY_GROUP_TRACE -off LEGACY_GROUP_DEBUG

And then you run the program to trace (lte-softmodem, nr-softmodem, whatever) as explained in basic usage.

To stop the recording, you simply press control+c to end record.

You send to Eurecom the file record.raw. The file T_messages.txt is not needed.

To get a list of options, run:

./record -h

The options -ON, -OFF, -on and -off are processed in order. In the example above we first activate all the traces (-ON) and then deactivate specific ones (more precisely, in this particular case: the groups of traces VCD, HEAVY, LEGACY_GROUP_TRACE and LEGACY_GROUP_DEBUG).

You can then replay the recorded file or send it to others so they can analyse things.
