Describe the bug
I got an error while running ros2 launch microstrain_inertial_rqt quickview_launch.py on ROS humble.

[rqt_gui-1] Traceback (most recent call last):
[rqt_gui-1]   File "/opt/ros/humble/lib/python3.10/site-packages/rqt_gui/ros_plugin_provider.py", line 80, in load

[rqt_gui-1]   File "/opt/ros/humble/lib/python3.10/site-packages/microstrain_inertial_rqt/utils/services.py", line 3, in <module>
[rqt_gui-1]     from microstrain_inertial_msgs.srv import DeviceReport
[rqt_gui-1] ImportError: cannot import name 'DeviceReport' from 'microstrain_inertial_msgs.srv' (/opt/ros/humble/local/lib/python3.10/dist-packages/microstrain_inertial_msgs/srv/__init__.py)

To Reproduce
Steps to reproduce the behavior:

  1. On a machine with basic ROS2 humble installed. Install the packages with sudo apt install ros-humble-microstrain-inertial-driver ros-humble-microstrain-inertial-rqt
  2. I launched the driver with no significant error ros2 launch microstrain_inertial_driver microstrain_launch.py and I can see the topics and data flowing correctly.
  3. I run ros2 launch microstrain_inertial_rqt quickview_launch.py and the error messages can be seen.

I can not see any messages with DeviceReport name

Expected behavior
I expected the rqt_gui to launch correctly. But there are python errors as posted before and plugin loading failure (probably due to python error)

Environment (please complete the following information):

  • OS: Ubuntu 22.04
  • Architecture: x86_64
  • ROS Version: humble
  • Sensor(s): 3DM-GX5-15

Modifications
I have not changed the code because I just installed the packages with apt.

Launch Parameters
I do not have a launch parameter file.

Additional context
Add any other context about the problem here.

I have the same problem in ros 1 noetic. I installed the rqt tools with apt-get install ros-noetic-microstrain-inertial-rqt and when I run roslaunch /opt/ros/noetic/share/microstrain_inertial_rqt/launch/quickview.launch I get the error

[...]
ImportError: cannot import name 'DeviceReport' from 'microstrain_inertial_msgs.srv' (/opt/ros/noetic/lib/python3/dist-packages/microstrain_inertial_msgs/srv/__init__.py)

The microstrain_inertial_rqt package is considerably broken since the release of 4.0.0. I have been meaning to fix it for some time, but have had other priorities, and unfortunately, that will probably continue for some time.

If anyone is interested in providing a fix for this, I am happy to review a PR. Otherwise, I will update this issue once the package gets fixed

I created a draft PR for this issue in the microstrain_intertial_rqt_common submodule.

It's still work in progress but it is ~80% usable at the moment. Several widgets are still not being mapped to data properly because the data format of certain topics changed.

I haven't tested this on ros2.
