With Mesh SDK 3.0.0 ,  i have tested with light switch example with one client and one server, it works. My question is is it possible that one server can communicate to another server in one network?  And how to use group address FFFF

Hi, 

Could you give me more details about your use-case? and what you are trying to do? 

You can't send messages from a server model to another server model. As for group addresses, have a look at this under "Adresses". You can see that group address 0xFFFF is a fixed address, and messages published to this address will be sent to all nodes.

You should be able to do this, you then need to implement both a client and server model on each node. If you want to publish/subscribe to a group address, then you can use one of the dynamically assigned address(Have a look at the link mentioned in the previous answer).

OK,thank you, is there any example to implement this code?

Unfortunately, we don't have an example for this.
