Constant Freestyle L2 failures

It looks like MM2s are no longer in production unfortunately. I'm assuming that as the libre2 is now Bluetooth enabled it's killed their business model, which is a shame. The actual hardware components aren't very expensive nor all that complex, I suppose I could hack something together, but waterproofing will be a bit of a faff unless I can find a donor device which is already integrated (Bangle.js perhaps, not sure if it has NFC though. The Puck.js does, but not waterproof, but might work as a prototype device.....)

I had the MM2 just sending scanning & sending a separate BT signal to a stand alone Watllaa watch. (It had a stripped down version of xDrip on the watch’s firmware.)
The battery was failing after charges with the MM2 so I invested in a Bubble mini.
Then the support stopped on the Bubble mini it would start sending nonsense to the watch then stop. (Even after a reset?)

The actual Libre 2 I have running with Diabox. It works great.

Well…? It also until a while back, worked great alongside librelink.
I have to activate the sensor with LL prior to Diabox then force stop LL or I get all sorts of errors?

Based on my experience.
The support for the BT bridges had stopped. I suppose there is no need to continue as the Libre is now a CGM instead of a flash.
I also believe that Abbott have altered the NFC side of things so only the LL app or the reader can make sense of the data.
Almost like it’s been encrypted??

I have also had some failures. Two failed immediately on application, one failed after a few days and I had a major hypo - unconcious for 7 hours!

I was relying on the alarms, but I am checking the reading on the phone every hour now.

Sorry to read of you being unconscious @mibby that must have been so scary. Just to clarify, when the libre failed did it not alarm to tell you it had failed?

Agreed, I think demand has dropped off so they've stopped making them, which is a shame, as a fallback would be useful still. Even better would be the devices actually working...

It's been like that for a while, one needed the OOP2 apk to allow XDrip+ to understand the data, which is another bugbear, why the lock-in.

And back to the main subject of the thread, my current sensor has lasted nearly 14 days with only a few drop outs though with a reasonably large (3mmol/l) but correctable offset (which self corrected yesterday and it's now <1mmol/l different.) Fingers crossed that tomorrow's sensor is at least as good, and hopefully better!

It did not!

That's awful. I hope you reported it to Abbott.

Yes, I have been having exactly the same problem. Very few sensors last the full 14 days.

I have had over 100 Freestyle Libre sensors now that have all said “the sensor has ended” before the 14 days have expired? Are you still having the same problem?

Here's my log fwiw: https://forum.diabetes.org.uk/board...ey-last-why-do-they-fail.114108/#post-1380157
