To develop a mesh network for ZigBee Communication. How to connect two or more routers for a mesh network.

[Harshad_Hapani]

There is not available example code for the router to router connection.

Can anyone help & guide to solve this issue?

The best is to look to an example.

For instance, if you take the example Zigbee_custom_ls_Client_Router and Zigbee_custom_ls_Server_Coord, you can use 3 boards, one for the Coordinator Board1 (with Zigbee_custom_ls_Server_Coord appli) , and 2 for the routers Board2 and Board3 (with Zigbee_custom_ls_Client_Router appli).

In this example, by pressing on SW1 button on either Board2 or Board3, you will see the Board1 receiving the strings via the traces. In this use case, all routers are sending a string to the coordinator. The 3 Boards are all connected to the same mesh network automatically at startup.
