The communication between topside computer and Blueos with the ROS extension

Blue Robotics Software

Hi,
We are trying to implement some perception and control algorithms on BlueROV2 via a topside computer.
First, we installed the ROS extension on BlueOS and attempted to use the package “bluerov_ros_playground” to extract some data and perform visualization.
Although the topics from BlueOS in WSL(Ubuntu 20.04 / ROS Neotic) can be seen, none of the launch files in the package appear to work properly. The error message are rather confusing - please see the screenshot below:

I’m wondering the issue is coming from the misunderstanding of network setting or any compatibility that we didn’t notice.
Any suggestion would be greatly appreciated.

Hi @ichen -
The ROV IP address is actually 192.168.2.2, and your computer should be .2.1 ! Maybe that is related to your issue?
