Hello,
it should be useful to have the app cnArcher working with firware version older than 15.2.
For example we were using version 15.1.5 and we have all our network configured with 15.1.5.
Every time a tecnician goes to a customer he has to spend time to upgrade the unit.
Moreover, all our SMs are pre-configured with version 15.1.5 so we lose a lot of time for every new installation in order to perform the upgrade and use cnArcher.
Thank you
