Hello, to let you know,
how to use the sensor longer than 14 days without hacking it. Use the app
Glimp . The freestyle libre meter stops reading after 14 days, but the sensor keeps sending glucose levels after 14 days.
Glimp keeps reading them !!! The sensor gives every reading a warning that glucose levels may not be accurate and that the sensor has expired, but its working fine, how long and how accurate may vary. So you better finger prick more often to check its okay.
I was searching how to get longer life out the sensor with NFC tag software so I kept the expired sensor in my arm for testing, tryed glimp and it was working fine with the expired sensor
You have to enable NFC on your smartphone, and keep the back of the phone very close to the sensor and wait for it to vibrate.
Hope it works for you too
