If you want ack on the internal send functions like:
present
sendSketchInfo
sendBatteryLevel

How are you supposed to know it worked when it returns void ?
What was the purpose in keep them special and not treated like any other message ?

Is this solved yet ?

The sensor clock and GW clock dont need to be synced, the node just need to back track how long ago the sample was taken.

So and example "123:23.7" in this 123 seconds ago the temp was 23.7 and default is 0.
I need this also to save power and use bulk sending, so sample one hour and then send that hour of data in a chunk.
