MESH LNP node polls the data storage location of the friend node

[zero]

Mesh3.2，How does the LPN node get the data of the friend node? Which API can the polled data use to read this data?

[Joakim Jakobsen]

Hi. 

Have you looked at the example documentation on our infocenter?

Low power node example

We also have a documentation page with a lot of useful information about Integrating Low Power node feature.

Integrating Low Power node feature

Which API can the polled data use to read this data?

Not quite sure what you mean by this. 
You can take a look at the LPN API here: 
Mesh LPN API reference 

This might be what you are looking for: 
mesh_lpn_friend_poll ()

This will initiate a Friend Poll. Calling this API can generate the following events:

NRF_MESH_EVT_LPN_FRIEND_POLL_COMPLETE
Which means that theThe LPN successfully polled all data from the Friend node.

Best regards, 
Joakim

And where can the polled data be found? The examples and the API is not very helpful to get this information. 

In the example the friend poll is iniated, however, there is no function handling the polled data.
