What is the maximum number of sleeping devices supported by the ZIGBEE coordinator?

That is dependent on which XBee module you are working with and what firmware version.

The S2C hardware with the Zigbee code can support up to 14 sleeping end device children. The S2 and S2B hardware can support up to 10.
