Zed-ros-wrapper is not working with a simulated camera from Isaac Sim

Software ROS2
1

I am getting this error when using the zed-ros-wrapper. I am using the data from a simulated camera in Isaac Sim.
OS: Ubuntu 22
Isaac Sim: 4.0
ZED SDK: 4.2
NVIDIA Driver: 560.35
Cuda Toolkit: 12.1
Note: I ran the ZED_Diagnostics and there weren’t any errors, and I can visualize the pointcloud in the ZED_Depth_Viewer using the streamer node in Isaac Sim. The problem occurs when using the ros-wrapper.

Hi @ShyamKrishna33
Welcome to the Stereolabs community.

Please note that the ZED ROS Wrapper package does not support simulation.
You can only use the ZED Isaac Sim integration with ROS 2.

Hi @Myzhar
I am actually using the same and I followed the official docs to use the zed with Isaac Sim and ROS2, but for some reason there is an error in using the Positional Tracking

Can you try to use GEN_1 instead of GEN_2?

This works!! Thank You
But may I know the possible disadvantages and precautions that I should be aware of when using GEN 1 in lieu of GEN2. And is there a way I can fix the problem and use GEN 2?

Hi @ShyamKrishna33
GEN_2 works properly with real IMU information at real IMU rates.
