New Firmware not compatible with current ros version

Hello,

today, we updated our Scene Scan to firmware version 4.0.0 and tried to launch it with ROS (we use the current version 3.4.0). We got the following error message and breakup of the node:
[ERROR] [1565856258.803210398]: ParameterException while obtaining parameter enumeration: Enumeration contained a ParameterID for which no name is known: 524

Best regards

Sorry, you are right. The ROS node was a little bit behind. The new version in the git repository is now compatible:
https://github.com/nerian-vision/nerian_stereo

A new release build has been triggered. Usually it takes a couple of days until new release packages are available on the ROS package servers.

Thanks for your reply. I'm sorry to say that, but I updated to ros version 3.5.0 and still getting the same error.

Do you have an older version of the libvisiontranfer library installed somewhere in a library search path?

Yes, there is an older version in the library search path. After moving this file, I could start the node. But why doesn't the executable find the newer libversion in the first place?

I'll check. I think there's something in our CMake script that we can do to improve this.

There's an updated CMake file in the git repository that hopefully solves this problem.
