Gazebo (Ubuntu 18.04, gazebo-9) connect Simulink(matlab2020b) correctly!
then i used "gz topic -l", i could see all the topic in gazebo, means the topic have been published.
Connectin between ubuntu and matlab correctly, then i try to follow the tutorial: use "gazebo read block" to read GazeboPlugin msgs, that ok!
but if i use "gazebo subscribe block" , there was no topic that i could choose, when i clic on "select", it shows no topic could subscribe...?
very urgent, please help meto figure out this question!!! Is it the issues of version of ubuntu or gazebo? or code? used google protobuf 3.0.0
thanks in advance !
