Problem in receiving data: xbee pro s2b

[embedded.world@aol.com]

I have to transfer data between two xbee modules wirelessly.
I don't have any setup to configure xbee by x-ctu
I have to configure xbee on the run with the help of microcontroller.
I am using Xbee Pro S2B.


1.Since xbee pro s2b don't let to set ""atmy" to I don't understand how to set xbee own address.

2. Below are code I have used for tx & rx.
In both codes I am able to configure xbee as per the code. I get ok reeponse from all the commands.
Tx code transmit data after that. But problem is rx don't receive data??

I have try to set different destination address of xbee's, same address but no help??


3. Tx code is below:

                                 Rest all pins on xbee are unconnected
