Ping function

[alfredocdmiranda]

I've been looking on forum's history and I didn't find anything efficient for this. So, I was thinking that would be good is there was a Ping-Pong function, so, in that way we could check if a node is alive and we can discover the network sending a ping to the broadcast address.

Sorry if I am wrong.

There is a heartbeat message in development-branch that does just this.

(But the node has to be awake of course...)

Nice @hek ! I see many intersting functions! Thanks!
Just one question... will I be able to send I_HEARTBEAT from controller to node(just to check if it is alive) or just the node can send this message?

Both ways. Node answers on this request. It is documented further down in the document.
