• Specifies frames to start or end transmission frames refers to the number of times a topic is sent, not the number of topics. In the example below, topics are sent in the range from frame 5 to frame 100, skipping up to frame 4. It is advisable to check in advance which frame range should be sent using rqt or similar.

  ros2bagsend --ros-args \
  -p bag_file_path:='test.db3' \
  -p start_frame_no:=5 \
  -p end_frame_no:=100
  

• Only analysis of statistical information is performed Analyze the list of topic names in the bag file and the number of assumed frames. It is also possible to specify start_frame_no and end_frame_no. If statistical_analysis_only is specified, no topics are sent.

  ros2bagsend --ros-args \
  -p bag_file_path:='test.db3' \
  -p statistical_analysis_only:=True
  

  Statistical information is being analyzed ...
