Same issue here. I hope you have solved the signal loss issue, but I have gone through the same procedure many times, and the problem always goes away for 1-8 hours, and then returns as bad as before. You can trust neither the Libre2 alarms nor the utterly incompetent and dishonest technical...

I am not sure this explanation is true. I have disabled Bluetooth in every device I have, other than the Samsung S21 Android phone hosting the LibreLink app, and still the Signal Loss occurs, rendering the system both useless and dangerous. And how absurd is it that Abbott admits that their...

Thanks again for your thoughtful response, BadaBing. I am in Canada, by the way. Most Canadians pay out of pocket for these defective and dangerous medical products. I have no desire to blame the front line tech support people, but they are the face of Abbott and they have been programmed to...

Thank you, Badabing, that was very informative. My interaction with Abbott technical support for ALL my failing Libre 2 sensors (on a Samsung S21 Android phone) has been nothing but a repetitive series of lies followed by squirming and claiming the lie really didn't happen. "No, no, what I...

NFC (Near Field Communication) is the channel when you scan your phone very close to the sensor (within 4 cm) and get your latest blood glucose reading. Bluetooth is used to connect your Libre 2 sensor to your smartphone (within several meters) so that the LibreLink app in your smartphone can...

Sorry barrym, I thought you were talking about the Libre 2 app. Okay, I will reinstall Juggluco and dig further as you suggest, and see if Juggluco can maintain Bluetooth connectivity and issue high and low alarms, unlike the worthless Libre 2 from Abbott. Thanks again, and back at ya soon!

Tried removing the Samsung S21 Android phone from its case, and the LibreLink app still has the alarm condition "Alarms are unavailable. Scan Sensor". Nothing so far has resolved this fatal error, not even the string of lies and nonsense that came from Abbot's technical support agents. Also...

Of course I have done all the things you suggested and more. When Libre 2 works (increasingly rare) it is perfect, as per my configuration. But no amount of “digging” can correct the endless Bluetooth signal failures, and hours spent with support agents likewise produces no happiness. Remember...

Thank you for the suggestion. I downloaded and installed Juggluco on my Samsung S21 Android phone. It is able to read the Libre 2 sensor by direct NFC scanning, but the app is very crude and it seems impossible to set up alarm limits, so I’m no further ahead. I let Juggluco add the end date of...

I downloaded and installed Juggluco on my Samsung S21 Android phone. It is able to read the Libre 2 sensor by direct NFC scanning, but the app is very crude and it seems impossible to set up alarm limits, so I’m no further ahead. I let Juggluco add the end date of the sensor to my Google...

Interesting, thank you. I am in Canada where I yesterday saw the Libre 2 sensors on sale for C$139 (roughly US$115). If I do a fresh install, the current sensor is trashed and the loss-of-signal error persists. So more useless and expensive advice from Abbott. I appreciate your suggestion of...

Reinstalling does not just lose your 90-day history, it also trashes your $100 sensor with whatever life it had left on it. Worst of all, it does nothing to solve the loss-of-signal and loss-of-alarm problem.

The Libre 2 is a dangerous medical product, and Abbott's response is to lie and obfuscate but never to provide any kind of solution. Your sentiments echo mine (see Alastair Gordon posting below). Just the fact that you cannot go back to an earlier version of the app before this horror show...

Abbott is selling a dangerously defective product, and lying to its users rather than admit they have a potential life-and-death defect in their product. My Libre 2 sensor is constantly losing Bluetooth connectivity to the LibreLink app in my Samsung S21 Android phone. People with type 1...
