Detailed Description
If you have another ranging device with different behavior (e.g. a sonar array), please find or create a different message, since applications will make fairly laser-specific assumptions about this data
MultiEchoLaserScanSubscriber receives multiEchoLaserScan values from a ROS 2 topic. Set the topic and node properties, then connect to the messageReceived() signal.
See also MultiEchoLaserScanPublisher and multiEchoLaserScan.
