I am running the `voxl_mpa_to_ros` node on my `Sentinel` drone, currently running the VOXL SDK 1.0.0.

It successfully runs, but as soon as I subscribe to the `/hires_large` topics, the node crashes.
The node does not crash when subscribing to the `/hires_small` topics.

Any idea of the solution?

I have the same issue. If you try it multiple times sometimes it will work but most of the times it will crash like shown.

@Tjark Same happening on the Starling! but if you subscribe to lower res it never happens (yet)
