Using "void request" without Controler.

[delinend]

Is it possible, to use the void request without a Controler?
The setup is Node1 sends a status to SerialGateway, and goes to sleep.
Node2 is asking for the status from Node1, on the SerialGateway (the Node1 is at sleep).
Do the SerialGateway keep track of the status from Node1, after Node1 is going for sleep ?

Yes, you can request from any node.

But keep in mind that serial gateway nor any other node automatically remembers any values. You would have to implement the receive-function and handle incoming req-messages yourself.
