Hi everybody,
do you know where i can find an example of the usage of message filter in a lifecycle node? The standard way "message_filters::Subscriber<sensor_msgs::msg::pointcloud2> subscription_point_cloud" does not work.
Thanks.
I found this issue: https://github.com/ros2/geometry2/iss... - it looks like this option is not there yet.
EDIT: I just saw that it was a MessageFilter class inside the tf2, not the ROS 2 message_filters, so it is probably incorrect. I hope there is some example how to do it correctly. Please add your code (MRE would be the best), so we could check it and maybe fix any issues.
Feature request - description
Similar to #70 and #94, the
MessageFilterclass needs support for lifecycle nodes.Implementation considerations
There could be a constructor that takes the required node interfaces, perhaps in addition to
rclcpp::Nodeandrclcpp_lifecycle::LifecycleNode.
