automatic data transmission between two zigbee

i designed one board with LM35 module placed on it in order to sense the temperature.The signal that comes from the LM35 module is connected to the zigbee module.
so can u please guide me the way how the other end zigbee module reads the data from the other zigbee when the power is turned on.

The 802.15.4 module is not Zigbee compliant. What are the part numbers of your Digi modules?
