WARNING: no messages received and simulated time is active. Laser Scan Matcher
ROS Kinetic - Ubuntu 16.04
Looking this up, all the forum posts I can find are either about gazebo or don't really have an answer.
Laser Scan Matcher node takes an input and produces an output. The input isn't empty, I checked with $ rostopic echo /theinputtopic.
If I put <param name="/use_sim_time" value="true"/>in the node launch file, and I do $rostopic echo /outputtopic , I get:
WARNING: no messages received and simulated time is active. Is /clock being published?
If I put <param name="/use_sim_time" value="false"/> in the node launch file, and I do $rostopic echo /outputtopic , I get absolutely nothing, just an empty new line.
Putting --clock as argument also doesn't seem to have any effect.
What's causing this error?
Have you solved this problem yet? If not, could you post the entire launch file, and maybe a screenshot of an
rqt_graphof the system running with the bag playback?
