Hello, I'm studying with pioneer3dx. I have to use sonar sensors on pioneer3dx and I must show these in the gazebo simulation. I did researched about this section this links; http://wiki.ros.org/p2os/Tutorials/Co... https://answers.ros.org/question/1374... https://github.com/tu-darmstadt-ros-p... And I applied these. I get this error. What should I do to get sonarArray data when pioneer3dx running at gazebo? (ROS1,melodic,gazebo9.0==>I'm new in this site, I can't add picture because of I've not enough badget. I wait for suggestion for about these.Thanks!)

Client [/rosPioneer2] wants topic /pioneer/sonar to have datatype/md5sum [p2os_msgs/SonarArray/2984921c09aef26ad253c7629937a5bb], but our version has [sensor_msgs/Range/c005c34273dc426c67a020a87bc24148]. Dropping connection.
