[Solved] publisher problem in hydro

edit

Hi everyone

I have a really strange behaviour I can not explain. I have a really simple program where I publish a message and then quit. When im not sleeping after creating the publisher, but i start immediately to publish the messages gets lost. Any ideas what the case may be? I am using hydro, and the roscore runs locally.

thanks flavio

#include "ros/ros.h"
#include "std_msgs/Float32.h"

int main(int argc, char **argv)
{
  ros::init(argc, argv, "publish_test");

  ros::NodeHandle nh;
  ros::Publisher set_control_active_pub = nh.advertise< std_msgs::Float32>("/pixhawk_bridge/control_active2",10 );


  ros::Duration(2).sleep();


  std_msgs::Float32 activate_msg;
  activate_msg.data = 0;
  set_control_active_pub.publish( activate_msg );
  ros::spinOnce();
  ros::Duration(2).sleep();




  return 0;
}
