Hello, I have read similar discussions but there seemed to be no conclusion. My config is also different with Ubuntu 20.04.5 LTS running on WSL2 for Windows. I have tried ROS2 Humble and now ROS2 Galactic with the same issue. Similar to others, I cannot see any ROS2 parameters, actions, services, etc., that the Create3 should be exposing. I only see /parameter_events and /rosout when I run 'ros2 topic list --spin-time 10 --no-daemon' as recommended. Here is the output.

dev@DESKTOP~$ export RMW_IMPLEMENTATION=rmw_fastrtps_cpp
dev@DESKTOP:~$ ping 192.168.1.48

dev@DESKTOP:~$ ros2 topic list --spin-time 10 --no-daemon
/parameter_events
/rosout
dev@DESKTOP:~$

I am running on a home network. I am able to ping the Create3. UDP also seems to be working locally when trying multicast receive and multicast send between Ubuntu environments.

Here is the system info on the Create3:

Here is my Windows 10 Home edition info on WSL 2:

PS C:\> wsl -l -v
  NAME            STATE           VERSION
* Ubuntu-20.04    Running         2

I have tried a native Windows 10 install of ROS2, but that is a mess of dependencies and I could not get it working. WSL2 should support all network connectivity so I would like to stick with that.

Here are my Create3 logs from this morning:

Here is my Create3 config page. I have saved and restarted the app while trying both supported RMWs multiple times in ROS2 Galactic and ROS2 Humble at this point.

Please let me know what other information I can provide to get through this issue.

Hi @stevenhasara, I recommend that you stick to ROS 2 Galactic and rmw_fastrtps_cpp for your setup, both on the robot and on your VM.

Can you provide more context about your test with multicast receive and multicast send? How did you run that to verify that multicast UDP is ok?
In any case, I recommend giving a try also at using unicast communication, as described here https://iroboteducation.github.io/create3_docs/setup/xml-config/#disable-multicast

For what concerns the log from the Create 3, there is indeed something strange there:

I have never seen this continuous spam; maybe it indicates some issues with the network interfaces on the robot.
@shamlian do you think that this could be a problem?

is this a normal Wireshark capture? From Windows and my WSL Ubuntu 20.04 env, I see that any ICMP protocol from the Create3 is flagged by the same error message. I opened up all Ports to the Create3 IP address and it still gives this error.

alsora Dec 28, 2022

No, this is definitely not normal.
I'm really not an expert of networks but I'm able to see the packets to/from my Create 3 using WireShark.

I don't know why you get this error; moreover, packets should all be marked as RTPS.

By default ROS 2 uses ports 7400, 7401, 7410 and 7411 (as explained here https://docs.ros.org/en/galactic/Concepts/About-Domain-ID.html).

Are you sure that the Virtual Machine can access those ports?
I usually work with Docker, where it's required to run with --network host mode to allow it to access all the network interfaces on the host machine (and I had troubles if I tried to simply specify a subset of ports).

stevenhasara Dec 28, 2022

It looks exactly the same when I Wireshark from Windows, where the ports are open. Is this a Create3 issue I should stop and troubleshoot before proceeding with any ROS2 or virtualization/network problems?

stevenhasara Dec 29, 2022

Good morning, @alsora. I installed Ubuntu 20.04 on a laptop (no virtualization), installed ROS2 Galactic per the official docs (https://iroboteducation.github.io/create3_docs/setup/ubuntu2004/), and everything works fine without any additional configuration. Thank you very much for your help yesterday. It seems like running behind WSL2 caused some networking complexity that I was not able to meet. Attempting to ros2 multicast receive and ros2 multicast send between my WSL environment and the laptop is not successful.

On to the fun part!

That's great @stevenhasara!
Have fun with Create 3 and don't hesitate to reach out for further questions.

Using ROS 2 on non-linux machines is not trivial; we hope eventually to contribute to the ROS 2 documentation with instructions on how to do that reliably.
