I am trying ROS2 on Rosbot2.0 with cyclone DDS.
When I checmed for topics using ros2 topic list, I see 4 messages from dds_bridge.
But when I tried to read the messages in the topics using ros2 topic echo topic_name. There is no information from the topic
Hi Jaswanth,
I’m sorry for long time of response.
After using command ros2 topic list
you should see 6 topics not 4:
/battery
/cmd_vel
/odom
/prameter_events
/rosout
/tf
Please confirm that you are using the newest image and you can see the same topics as I see.
Best regards,
Hubert
I got it working…Forgot to run the serial communication service.
