[uff1199]

Issue description

I am not able to launch the ROS2 driver with ROS Humble on ubuntu 22.04 from the commit: 1ffd6a3

Instead it is running with commit: 29397f6

Code example about how to reproduce the issue

cd ~/dev_ws/src && git clone -b humble https://github.com/basler/pylon-ros-camera pylon_ros2_camera -b humble
cd pylon_ros2_camera

git checkout 1ffd6a3

cd ~/dev_ws/src/pylon_ros2_camera && git clone https://github.com/ros-perception/image_common.git -b humble

cd ~/dev_ws && rosdep install --from-paths src --ignore-src -r -y

cd ~/dev_ws && colcon build

cd ~/dev_ws && . install/setup.bash

ros2 launch pylon_ros2_camera_wrapper pylon_ros2_camera.launch.py

Is your camera operational with the Basler pylon Viewer on your platform?

Yes

Hello @uff1199
This is not due to the commit as there were only changes made in the documentation. It is more likely a problem coming from your camera, because of that:
[pylon_ros2_camera_wrapper-1] 1723201304.853255395 [basler.pylon.ros2.pylon_ros2_camera_base] [ERROR] An image grabbing exception occurred: The camera device does not support waiting for frame trigger ready.
I'll get in touch about that. In the mean time, do you have another camera, maybe more recent, to test your code with?

[uff1199]

Hi @FrancoisPicardDTI,

as mentioned in the description the camera is operational with the ROS2 driver built on [this commit]( commit 29397f6). However, it's not running with the latest changes made to the humble branch in the repository.

Thank's a lot for your help!

[FrancoisPicardDTI]

Hi @uff1199
Should be fixed now. Try the newest release on the humble branch and let me now if it is working.
Apparently the WaitForTriggerReady() function is not supported by some devices now. I tried with a dart model and I had the same problem. Fortunately there's a CanWaitForTriggerReady() that can be used beforehand.

[FrancoisPicardDTI]

The problem is considered as fixed. Please reopen if it is not the case.
