how to addressing 6 xbee for implemetation the mesh topology ? the 6 xbee for 5 router and 1 coordinator

If you are using the Zigbee based modules, there is nothing you need to do. They will automatically form a network when when the six routers are brought in range of the coordinator for the first time. The routers will also send their data to the Coordinator by default and the coordinator will send broadcast packets to all routers.

how to download setup required to make the router can send the coordinates to the API mode?
