Hi,

I am sorry for the delayed response.

The handle is the same as the one returned through the p_model_handle parameter of access_model_add(), and it identifies the model instance that received the message. It only becomes useful once you have multiple instances of the same model. In the simple on/off model, the p_args argument is used for this purpose, but for more complex models, this isn't necessarily possible.

In case you are familiar with BLE and the nRF5 SDK and SoftDevices, it is analogous to the concept of characteristic handles in BLE.

Hi,

This is part of our simple on/off model implementation. We do have a fairly detailed walk-through of it in the Creating new modules chapter of the nRF5 SDK for Mesh v2.0.1 documentation, and it covers the details of the handle_status_cb() function. I highly recommend going through the full page on how to implement a model, in order to thoroughly understand how things fit together.
