TF2 message not in ros2 message list

Hello,

I've created ros2 bag that is composed of TF topic that publish tf2_msgs/TFMessage. However I get the following error, when loading the bag

Is there a way to have those message in matlab ?

Thanks in advance for any answer.

Hi Megane,

You need to download the tf2_msgs from the web. Then run ros2genmsg on the downloaded message package before you read the messages from ros2bag.

Let me know if you run into any issue.

Thanks,

Hi Jagadeesh,

Shouldn't tf2_msgs be built-in in like they are in the ROS1 side of the toolbox ? It's a working solution to compile it as a custom message but it seems weird as it's already built-in other ROS envrionnements.

Cheers,

Hi Antonie,

We are working on this request. In the future releases of MATLAB, tf2_msgs will be part of ROS toolbox for ROS2 also.

Thanks,
