Nordic BLE Mesh Flooding issue

[m10817012]

Nordic BLE Mesh transmission is transmitted through the Publish address bound to the model in the Instance, so that subscribers can receive packets.

As shown in the figure below, I found that Nordic BLE Mesh can only be transmitted through the Publish address bound by the model, so there is no concept of Flooding?

I want to know how to implement BLE Mesh Flooding? Exmple: S->D

Or am I misunderstanding?

Hi Guanting-Lai, 

Your imagination of flooding mesh is correct and it's how it should work. 

As far as I know the router on our mesh stack doesn't filter out package that's not directed to it or to the publish model of it. 

How did you test and verify what you have observed ? 

Note that only the node that the message is directed (destination address) to will process the message. Other node will just relay without process/consume the message.
