    I wrote a subscriber node to get the ‘data’ field of the ‘sensor_msgs/Img’ for rostopic ‘/tracking’. But not getting any output. I even tried echoing the topic, but still no output. Can someone explain the reason? The required services are already enabled and running.

          @張為超 Yes it does. Voxl2 is the master. I am running the voxl mpa to ros node in voxl2 and then trying to echo the published topics in my PC.

            I think you can use voxl protal first to check if the camera configure is okay, then use "rqt_image_view" in ros to check ros configure.

              @張為超 It worked. I setup my Pc as the master this time, and it worked in that way.
