I am trying to work on echo response in simulator. Is it possible to use this feature to get response from other messages other than the ones mentioned as default messages?  
I have tried with s2f39 and I was expecting as s2f40 response. When I send a message, I am not getting any response. It shows none at the console.

This is how I have done. How can I fix this issue?
