sonar_to_laser.py no messages received and simulated time is active. Is /clock being published?

[ghost]

Hello

I tried to use your code to convert my sonar sensor msgs to laserScan and make use of it in my navigation to avoid obstacles detected by range sensors so I modified only the frami_id and name of topics

but when i tried to echo the topics nothing was displayed and I got this message
"WARNING:no messages received and simulated time is active. Is /clock being published?"

Also about this line, the topic car/power publishes whata data?

sub = rospy.Subscriber('car/power', Vector3, callback)

Thanks

Hi,
sorry for the late reply but I didn't receive a notification about the issue..
Do you still have this problem?

In case you are using simulated time, can you check that the original sonar messages are published with the correct timestamp (in the simulated time)?

Otherwise if you are publishing messages from the sensor (and not bagfile), set use_sim_time to false

ciao
