I've been following the tutorial for using rosserial with arduinos. It uses ros 1 utilities. When I looked up ros 2 and rosserial I found a post saying that rosserial is not compatible with ros 2. The github page for rosserial links to a ros 1 wiki page with no reference to ros 2. So I just want to confirm that rosserial is not compatible with ros 2 and that there is no ongoing work to make it compatible.
