Hello,

Can I implement an action server in C++ and call it from a client in python (i.e. from a Smach script)? As far as I understand the ROS architecture, so long as they share the same .action file, this should work, no?

Thanks.

Yes. If both client libraries have support for actions and have access to the same action definition, it should work.

Python and C++ are both well used and supported.

Ok, this is all as expected then! Thanks!

Hi; What about vice versa? As I have not completely understood it, would you please give me more details and example?

Vice versa will work as nicely. There is nothing special to do, just to implement a action server in a language and the client in another language. So long as the cores are ROS compatible, it will work (because the messages use the same ROS protocol).

There is a reference tutorial here which already explains it all.
