Hi @Bardhitoo are you sure this is not a ROS 2 issue instead of a ZED ROS2 Wrapper problem? The ZED Wrapper does not use UDP communication if not through the ROS 2 DDS Middleware. Please check your ROS 2 configuration, the DDS Middleware that you are using, and the UDP ports that it requires, maybe they are in conflict.
Start from here:
PS We do not officially support the ROS 2 Iron release. We never tested the wrapper with this distribution.
Let's continue the discussion on the Stereolabs forum. Closing the issue.
Preliminary Checks
Description
My team and I are currently facing the issue of robot disconnecting when connecting ZED2i camera with laptop (via ROS2) making it impossible to use both at the same time.
Everything runs smoothly when computer is connected to either robot or ZED 2i. Once both are connected to the computer, the issue comes up. The problem seems to be consistent regardless of the order of connection with laptop (1. ZED2i -> 2. Robot and 1. Robot -> 2. ZED2i).
Steps to Reproduce
ros2 launch zed_wrapper zed2i.launch.py
)...
Expected Result
No errors in communication between ZED2i <=> PC <=> Robot
