The environment:ros2-foxy
I'm a newer to ros2 .I want to visualize point cloud data of velodyne-16 with the help of ros2 and rviz2.I have installed the driver follow https://github.com/ros-drivers/velodyne/tree/ros2
.Set the following:
When I run the command,ros2 launch velodyne velodyne-all-nodes-VLP16-launch.py
,and get:
[velodyne_driver_node-1] [WARN] [1627545389.611428642] [velodyne_driver_node]: Velodyne poll() timeout
[velodyne_driver_node-1] [WARN] [1627545390.613130216] [velodyne_driver_node]: Velodyne poll() timeout

[velodyne_driver_node-1] [WARN] [1627545392.616064299] [velodyne_driver_node]: Velodyne poll() timeout
when I run the command ros2 topic echo /velodyne_points
,and get empty.
