I have a network of 10 units consisting of XBee-Pro 900HP modules, operating in synchronized sleep mode.
Each unit processes some data every wake cycle and then sends a result via the XBee module to some main unit.
The main unit collects the results from all units and performs some additional processing.
For my application I must perform this processing on results which belong to the same wake cycle of all units. Since not all units begin to operate at the same time I can't use a simple counter/timer.
Since the XBee modules are already synchronized, Is there a way to get a clock or some other synchronization signal from them?
Thanks in advance
