Accessing mesh relay data from the application layer in Zephyr

[AndyM]

Is there a way to access the data that comes into a provisioned node and is relayed on the mesh network, from the application layer in Zephyr?

I have a battery models erver and  I set it up for publishing to a certain address

On another device I subscribed to that address and in the RTT log I  see the data coming in and being relayed by the mesh stack but don't see a way to access it from my application.

There are callbacks in mesh model definitions , i.e BT_MESH_MODEL_CB and BT_MESH_MODEL_VND_CB  that use  bt_mesh_model_cb but it does not have any functions to examine the incoming data. What's the proper way to do this under Zephyr?
Thanks

Hi,

Are we talking about receiving data on the device and model that the message is addressed for, or are we talking about looking at the data on a Relay node in-between? On Relay nodes you cannot see messages that are not addressed to the node, and the messages are also often encrypted using an application key that is not present on the Relay node.
