2020-11-02 02:53:46 -0500 marked best answer ros2: Clock sleep_until

Hi,

Is there an implementation available for sleep_until or sleep_for with Clock interfaces on ros2?

The document here says it does, http://design.ros2.org/articles/clock... but could'nt find.

Please help.

2020-05-08 17:00:43 -0500 marked best answer graph listener ros2

Is there any documentation or notes available for understanding how to work with graph listener?

I'm trying to port/get rqt_graph working with ros2 and trying analyzing differences. Where I see with ros2 we do not have a framework for mapping node_names to topic_names, which is used with rqt.

Any clues/directions would be really helpful.

2019-05-20 01:17:23 -0500 marked best answer Implementing SubscriberStatusCallback within ros2

Hi,

When reading image_transport source code, ended up at a point where we need to use SubscriberStatusCallback.

How do we implement the same on ros2? (LifeCycle nodes?) They do not let enable us to develope code for connect/disconnect callbacks.

Any suggestions on the same would be mighty helpful.

PS: I'd asked the same question on discourse. Moved it here.

2019-03-20 17:39:32 -0500 marked best answer rosbag message instance & ros1_bridge help

Hi,

I was working with some tools for ros2 when I came across rosbag and it's message_instace class. On the same topic, I started understanding the ros1_bridge.

I'd like to get more detail on how ros1_bridge understands the message_instance data published by rosbag and converts the same to ros2 format and re-publishes.

Could anyone help me with docs/links or any suggestions?
