Freestyle Libre 2 Sensor & App Problems

Hi! I'm in Sydney, Australia. For almost a year now, I've been using this sensor, which connects with my Samsung Galaxy A31 mobile phone - to give me blood sugar readings, and, most importantly, alarms when these go too high or TOO LOW. Now, my alarms aren't working much at all, causing me heaps of problems - particularly overnight. I'm now having to set alarms on other devices - to wake me up, so that I can do a finger-prick test, so I'll survive the night. Literally! Last week I was hospitalised, after suffering a sudden hypo collapse at my local supermarket.

This week I've been in contact with my Diabetes Educators and with an Abbotts' representative. I'm not sure what's at fault - the app OR the phone. Nobody can give me a straight answer. Now I'm about to buy a new phone AND go to a new endocrinologist.

Has anyone else had a similar problem? If so, I'd love to hear from you.
 
Alarms are a bluetooth connection between the sensor and the phone.

Can you be more descriptive on 'much at all'? Is that NOT?

Is BT on? Is there any message in the LibreLink app about alarms?

What has changed recently? Any different apps loaded, updates?

Have you tried a reboot?
 
I hate to tell you this but you are much too dependent on an “alert system” that’s too complex to be reliable. There are too many ways it can break down: the phone, the sensor, the software, the bluetooth connection. Added to that, CGM is inherently less accurate, slower to detect changes and less reliable than conventional blood sugar testing. I would reassess everything you are doing in your daily routine that led to you winding up in the hospital, including diabetic unawareness. You need a better system and I doubt that any CGM is the magic bullet here.

Hi,

I’m fully hypo aware. But in my experience the Libre 2 coupled with a third party app (Diabox, which can be calibrated to my meter.) taking a BT feed from the sensor to an old Samsung Galaxy Note 9 allowing 5 minute updates on BG gives me a 5 or 10 minute warning before I feel the low.. Disconcerting at first but then I felt the hypo as I shut the repeated alarm off.
The tech for me limits the severity & extent of the low.
I can leave my phone on charge at the other end of the house, it will pick up and scream..

Staying hydrated helps with the accuracy of these sensors that work by interpreting glucose in interstitial fluid.
On changing sensor, I go into systems apps on my device, then Bluetooth & clear the memory cache.(before scanning for a start up.)
