Hi, My SICK LMS 200, requires around 25 seconds for being initialised. Currently the sicklms node that can be found in sicktoolbox_wrapper (and by following the tutorials) generates an error as there is not enough time for showing a green led on. I have been looking around the Sick LIDAR Matlab/C++ Toolbox, and I am not sure whether it is a good idea to modify the option DEFAULT_SICK_LMS_SICK_MESSAGE_TIMEOUT for increasing the waiting time from all sensor messages. Moreover, I updated the file: `rospack find sicktoolbox_wrapper`/ros/sicklms/sicklms.cpp for waiting 20 seconds and call again sensor initalisation with something like this: try{ sick_lms.Initialize(desired_baud); //desired_baud=38400 } catch (...) { int time_wait=20; if(!sick_lms.IsInitialized()){ sleep(time_wait); sick_lms.Initialize(desired_baud); //desired_baud=38400 } After doind this the node works. However, does anyone has a better idea of how to correct such issue? Kind regards, Renato. _________________________________________________________________ Hotmail: Powerful Free email with security by Microsoft. https://signup.live.com/signup.aspx?id=60969
