+            By default, the "Name" parameter (esp.param.name) changes are handled internally. If Applications
+            want to handle this themselves, this config option can be enabled. Please ensure that you update
+            and report the name parameter in your callback so that it reflects correctly everywhere.
+            If no device callback is registered, the name paramater will be handled internally.
