two way communication not happening


Thanks for your reply. Actually ‘SC’ value of my coordinator was set to ‘FFFF’ after changing it to ‘FFFE’ I am able to communicate between coordinator and router. But communication is one way only. I am able to transfer message from router to coordinator but not from coordinator to router. Now i am testing this using next gen X-CTU not using any python script.

Try setting the DL and DH of the Coordinator to match the SL and SH of the router.
