In UE4 4.9 C++, how do I send a message from one actor to another using the UE4 messaging system?

Apologies if this question has been asked before. I am making a modular robot simulation environment using UE4 4.9. I have had a lot of success in my endeavors and have found UE4 well suited to my application, but I would like to implement message passing between connected modules using the Messaging system in UE4. I have a rudimentary message passing system implemented but I would like to use something more abstract and powerful. Is the Messaging module in UE4 good for sending messages from actor in actor in C++? Can I simply create an endpoint at each module actor and then send messages between endpoints? Or is this a poor use of the Messaging module?

Just in case the above isn’t clear. Imagine two actors in the same scene. I simply want to create a messaging endpoint at each actor and send messages between these actors. I am trying to simulate wireless communication between robotic modules during runtime. I am trying to determine if the UE4 messaging system is a good use-case.

If this is a good use of the module, can someone suggest some example C++ code for simply setting up an endpoint and communicating with simple messages? I have had trouble finding any example code. I am having a little trouble getting started. Thanks in advance for any help. Again, apologies for the question, I am very new to UE4.
