XBee‐PRO® 900 RF Modules
the sync will be rejected and a corrective sync will be sent to the sleep coordinator. Deployment
mode can be disabled using the sleep options command (SO).
A sleep coordinator which is not in deployment mode or which has had deployment mode disabled
will send a sync message at the beginning of the wake cycle. The sleep coordinator will then listen
for a neighboring node to relay the sync. If the relay is not heard then the sleep coordinator will
send the sync one additional time.
A node which is not acting as a sleep coordinator which has never been synchronized will send a
message requesting sync information at the beginning of its wake cycle. Synchronized nodes
which receive one of these messages will respond with a synchronization packet. Nodes which are
configured as non-sleep coordinators (using the SO command) which have gone 6 or more cycles
without hearing a sync will also send a message requesting sync at the beginning of their wake
period.
The following diagram illustrates the synchronization behavior of sleep compatible modules.
