I am using ubuntu 10.04 and ROS electric. I followed the tutorial on http://www.ros.org/wiki/sicktoolbox_wrapper/Tutorials/UsingTheSicklms When I set the baud rate to be 38400: rosparam set sicklms/baud 38400.The laser works well,but there is a waring: <pre> A scan was probably missed. </pre> However,when I set the baud rate to be 500000,the laser can't work ,of course ,the baud of laser is 500k.The error is as follow: <pre> Attempting to set requested baud rate...
