publish visualization_msgs/Marker.h with rosserial.
I'm trying to publish marker to rviz with rosserial. I use Arduino Mega 2560 , ubuntu 14.04 and ROS indigo. in every time I run the arduino node after uploading the code on arduino board, an error "[ERROR] [WallTime: 1529597748.845483] Tried to publish before configured, topic id 125 " appers. this is the code I use https://github.com/toqaelshahat/marke... why does this error appear and how to handle it and what is the wrong with the code ?
Can you please update your question with a copy and paste of the entire error?
