Hi
@Melgar .
The L2 became a full on CGM on release. Prior to that the Libre MKI was a flash monitor that needed NFC scanning.. Though there where a couple of 3rd party Bluetooth “bridges” in the L1 era that could constantly NFC scan & send readings to 3rd party developed apps like Diabox or Glimp?
However with the Libre 2 & the plus (15 day sensor.) it still needs to be NFC scanned on initial start up to initiate BT pairing with the device reading it.. Each sensor has a unique code.
My only gripe is watch battery life. The tech as it stands right now works fantastic for me..
I rarely pull my phone out of my pocket. & only use the alarms on the watch as a discreet buzz.
I don’t even pull my wallet anymore with “tap & pay.”
