XBee Pro Node discovery Error


In My project i am using 2 XBee pro S2B modules loaded as API firmwares. One is for coordinator and one is for End device.coordinator is connected to PC with X-CTU,End device is connected to microcontroller.

Problem is in X-CTU side i am sending node discovery frame i am able to receive myid,64 bit address,node identifier…values for the end device.here i am getting proper response frame.

After that in end device side i am sending the same node discovery frame,now i am receiving modem Status as ERROR.

Can you tell me is it possible to get the proper response for node discovery at End Device side?

If it is possible please give the proper solution.

Thanks in advance.

are you using at command ND?
