I was wondering what all you can do with an ACK, can you get the node it was from? Perhaps use this or some other method to que a retry after a minute or two when the ack fails?
NOTE: I edit my first question, as it was unclear, and I found out more since I asked.

And an ACK can contain data, like counters, or additional information.
For example, a node wakes up and sends a packet to the gateway. The gateway can not only ACK, but also inform the node (using custom content) that there is information queued up for it. Or maybe a more reliable method is to inform the node that there is NOTHING queued up for it and the node can go back to sleep. In this case, getting a different message or missing an Ack might keep the node awake and going back to the gateway for more stuff. Lots of options...
