Zigbee Mesh Networking - S2C PRO

I have to form the Mesh network using 4 Zigbee modules. Out of which 1 will be a Coordinator and 3 will be acts as Router. The router should send the MAC ID of each individual router to the coordinator and it should be read by the Controller which is placed at the Coordinator. Just I require a setting for 1 Coordinator and 3 routers. I have formed the Mesh network as attached. But could not able to read MAC address at Coordinator.

All Zibgee Modules are battery operated mode only. We dont have to connect XCTU software to every Zigbee Module.
