Hi all:

        as we know,  the LPN device needs to get it's  messages from it's friend node.  but  I don't know the procedure of LPN establishing friendship with it's friend node.

        I want to know if there is any detail steps!

    

  thanks!

Hi,

You meant to say that your LPN device is not establishing a friendship link with the friendnde (present in the same network in range)?

Which mesh application are you using as LPN and frined node?

This friendship establishment procedure is taken care by the mesh core stack.  Could you please collect the model traces and share it with me?

But my LPN devices have not sent the Friend Request message? -> How did you verified it?

Thanks,

-Dheeraj

Hi,

Mesh core handles the friendship establishment procedure based on the parameters given in the application (wiced_bt_mesh_core_config_t).

If you want to know the detailed step, then i would prefer you to go through the SIG mesh spec.
