How do i provision additional / alternative models in the light_switch example.

[RSA]

setup:

segger V4.20a

windows 10 pro

SDK: nRF5 SDK for MESH 3.2.0

hardware;

NRF52840

I am trying to implement the simple_on_off model instead of the regulat generic_on_off. 

This is being done as a proof of concept, to assure that the model in question is working, before trying to implement my own. I am aware that the purpose of the models are quite simmilar. My current implementation doesn't change the provisioner or any config files, other than adding the simple_on_off source files and modifying the main function.

These are some notable changes:

const simple_on_off_client_t m_on_off_client =
{
    .status_cb = app_on_off_client_status_cb,
    .timeout_cb = app_timeout_cb
};


//-------------------------------------------------------------------------
static void models_init_cb(void)
{
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Initializing and adding models\n");

    for (uint32_t i = 0; i < CLIENT_MODEL_INSTANCE_COUNT; ++i)
    {
    
      m_clients[i]=m_on_off_client;
      
      __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "added client: %d\n",i);
        ERROR_CHECK(simple_on_off_client_init(&m_clients[i], i + 1));
    }
}

//--------------------------------------------------------------------------

Apart from that i've ofcourse defined the cb functions, and made some other button configurations, but i doubt that's relevant.

My question is which modifications and considerations i'll need to make in order to provision.

Hi. 

Did you take a look in our documentation? We have a dedicated section of the documentation about Creating new models, and how to add the Simple OnOff model. 

You should be able to find everything you need there. 

Best regards,

Hi Joakim

I have already tried following the provided guide, but unfortunately to no help. As i am already using the simple_on_off models, i figure that the models should be intact, all the functions mentioned in " Creating new models" are already called.

The modifications i've made to the simple_on_off model is changing the server and client model ID's to be the same as the generic_on _off (keep in mind that the generic_on_off model isn't implemented simultaneously). i also kept the generic_on_off  URI. I did all this under the preconception that the provisioner, wouldn't need to be changed.

I however end up getting an error from my provisioner.

i am guessing that the error is related with some expectations coming from the provisioner not being met by the client_model, but i can't figure out which.

I solved the error at hand:

The error code was 2 (type access_status_t) meaning

"The provided Model index is not valid in this Element."  My mistake was not defining the proper company_ID in node_setup.c, i fixed it by changing the value to "ACCESS_COMPANY_ID_NORDIC"

but now i have a different error:

<t:    6903896>, node_setup.c,  267, opcode status field: 1 

"The provided value is not a valid address in this context."

I haven't figured out how to fix this yet.
