Xbee Pro with Relay?

I want to send some data from Coordinator to Router, then Router sends the same data to End Device. The End Device after doing some calculations, sends the Data to Router and Router sends the same data to Coordinator. So basically Router is just a range extender working as a bridge between Coordinator and End Device.

i have tried changing my modules to Coordinator, Router and End Device. The problem is, there are options of Coordinator and End Device in XCTU Software but there is no option of setting a module as Router (Relay). What arrangements do i need?

Should i Set one as Coordinator and other 2 as End Devices? Will it suffice the purpose?

Bump!!!

Nobody ever tried this??
