Excuse me sir, in order to change the scanning angle of the laser, I changed the values of "active_sector_start_angle" and "active_sector_stop_angle" in the program "sicknav350_node.cpp", nothing has changed.But I don't know why. Can you help me? Thank you!

Hi, I have cloned your sicknav350 repo.
And I've changed the sicknav350.launch as shown bellow.
......
......
<launch> <node pkg="sicknav350" type="sicknav350_node" name="sicknav350" output="screen" > <param name="scan" value="scan" /> <param name="publish_tf" value="true" /> <param name="publish_odom_" value="true" /> <param name="publish_scan" value="true" /> <param name="port" value="2111" /> <param name="ipaddress" value="192.168.0.10" /> <param name="inverted" value="false" /> <param name="fram_id" value="front_laser" /> <param name="fixed_frame_id" value="front_mount" /> <param name="laser_frame_id" value="map" /> <param name="laser_child_frame_id" value="reflector" /> <param name="resolution" value="1.0" /> <param name="start_angle" value="0.0" /> <param name="stop_angle" value="360.0" /> <param name="scan_rate" value="5.0" /> </node> </launch>

Then, I've got error "Incorrect message" as shown bellow
