sleep time accuracy

0 votes
I'm after opinions on the accuracy of the sleep times. The scenario is that Xbees can sync at startup but they may move out of range for days at a time. So I want set sleep and wake times that guarantee they re-sync when they come back in range.

For example.
If I set
non sleep controllers to sleep 4 seconds, wake 1 second.
sleep controller to sleep 1800s wake 10 seconds

when the non sleep controllers sync they will be on 1800s/10s.

If they dissappear for 72 hours will they still be able to sync with others?

I can't find anything in the manual to give me confidence it will.

What is a nice feature is that if I power cycle the non sleep controllers they will revert to their original 4s/1s cycle. This is handy for re-synching with the sleep controller.

Opinions please. Anyone have any real work/ measure experience on this?
