Detailed Description

A template class for creating Generic User Property Server models.

This class is derived from meshXServerModel and provides a convenient interface for creating Generic User Property Server models. It handles the Generic User Property state change notifications from the MeshX stack and publishes the state change event to the element layer.

Member Function Documentation

element_state_change_handle()

meshx_err_t meshXGenericUserPropertyServerModel::element_state_change_handle ( void )

overridevirtual

Handle state change request from element.

This function is called by the parent element when a state change request is received. It validates the request and returns a result to the element. Note: The actual state is maintained in the element layer, not the model layer.

Returns

• MESHX_SUCCESS: State change handled successfully
• MESHX_INVALID_ARG: Invalid parameter
• MESHX_INVALID_STATE: No state change detected

Implements meshXModelIF.

{
    auto *el_state =
        static_cast<meshx_gen_property_model_state_t*>(this->get_parent_element_state());
 
    if (!el_state) {
        MESHX_LOGE(MODULE_ID_MODEL_SERVER, "Invalid parameter in element_state_change_handle");
        return MESHX_INVALID_ARG;
    }
 
    if(el_state->property_id != model_state.property_id)
    {
        el_state->property_id = model_state.property_id;
    }
    if(el_state->access != model_state.access)
    {
        el_state->access = model_state.access;
    }
    // Note: property_value is a pointer and should be handled carefully
    // The actual value management is typically done at the element level
    return MESHX_SUCCESS;
}

model_from_ble_cb()

Parameters

[in]	p_dev	Pointer to the device structure
[in]	model_id	Model ID associated with the event
[in]	params	Pointer to the event parameters

Returns

MESHX_SUCCESS if successful, error code otherwise

    if(model_id != MESHX_MODEL_ID_GEN_USER_PROP_SRV)
    {
        /* Callback triggered not for this model */
        return MESHX_SUCCESS;
    }
 
    auto *param = static_cast<meshx_gen_srv_cb_param_t *>(params);

model_send()

meshx_err_t meshXGenericUserPropertyServerModel::model_send ( meshx_gen_property_send_params_t * params )

overridevirtual

Send a packet to the MeshX stack based on the given parameters.

This function takes a pointer to a meshx_gen_property_send_params_t structure as input and sends the corresponding packet to the MeshX stack for processing.

Parameters

[in]

params

Pointer to the meshx_gen_property_send_params_t structure containing the parameters
