Zigbee pro S2B Acknowledgement Error

Hi,

I am new to this.In my project i am using Zigbee pro S2B module,Problem is with out using Acknowledgement (Frame ID value is 0x00) i am able to transmit data properly from End device to coordinator.
frame format is
7E 00 16 10 00 00 13 A2 00 40 7C 0F D2 FF FE 00 00 54 78 32 43 6F 6F 72 65

Suppose if i am enabling the Acknowledgement (Frame ID value is 0x01) at the time i am able to transmit some packets after that i am not able to transmit data.
Frame format is
7E 00 16 10 01 00 13 A2 00 40 7C 0F D2 FF FE 00 00 54 78 32 43 6F 6F 72 64

Can you please help me how can i transmit data contineously by using Frame ID value 0x01.

Thanks in Advance.

What you can do is you can transmit each frame with different packet identifier value from 0x00 to 0xFF.
