Hi @premranjan,
You are right, you have to bind the coordinator with the router, it can not be bonded with the SED.
‘Finding and Binding’ is the process whereby controlling devices find controlled devices by matching operational clusters and create entries in the Binding table.
The Coordinator supports Finding and Binding as an ‘Initiator’ that tries to find targets to bind to. For the purpose of the demonstration.
The Router supports the On/Off cluster as a server and implements the Finding and Binding process as a Target.
The End Device supports ‘Finding and Binding’ as an Initiator that tries to find targets to bind to.
To start Finding and Binding as an Initiator, first trigger Finding and Binding on any ‘Target’ device (such as the Router in this Application Note) and then do either of the following on the Coordinator (Initiator).
Regards,
Mario
