Detailed Description

A template class for creating Generic Location Server models.

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

element_state_change_handle()

meshx_err_t meshXGenericLocationServerModel::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.
