Nexx Garage NXG-200 - What does BLE activation mean?

This option shows up under the Shared User screen if you are using a NXG-200 device. 

BLE activation means you only allow the shared user to activate the device through Bluetooth. This means the shared user has to be physically present to connect to the device and they won't be able to activate the device through their phone's internet connection.
