I woke up this morning and there was a diagonal red line through the sensor icon. The reader won’t scan the sensor and it just times out. It’s only been activated since Monday ~ 5 days.

Can’t find any info or workarounds for this issue. Contacted abbot but they have just replied with their usual ‘generic’ response.

Any ideas ? To me it appears the sensor is completely dead .

 
I don’t have the libre reader I just use my phone, could you ty scanning with your phone, (if you haven’t already), to determine if it’s the reader or sensor. I have nothing else up my sleeve if that doesn’t work, maybe someone more versed in the libre may have an idea or two.
 

Unable to use phone (not compatible) otherwise would have tried
 
Hi @Wurst ,

I'm a phone user too. (I don't have the scanner.) but what I notice on your screenshot is the battery icon looks empty?
(I'm used to seeing the icon on other devices with bars..)
Could there be a power distribution issue with the device due to low battery?
 

This is something I tried ie to give it a full charge , with no difference. At the time of photo it was charging , it was 1/2 charged when I first tried it this morning. I’ve had low power warnings before and it still scanned
 
Sorry for my ‘helpful’ suggestion, my thoughts/suspicions are if that signal on the reader could mean an issue with the NFC of the reader device rather than the sensor. Any way of doing a CTR+ALT+DEL? But tbh I’m not really able to give advice on the reader as I have never seen or used one.
 
Have you tried restarting your scanner? Hold the button down for ten seconds and select poweroff and restart.

OK? Another idea. Your thread title says "Libre 2." (Incidentally I didn't realise they were out this early.)
But I know there were software updates for the scanner & phone app recently. Are you updated?

Only about 20 times this morning :-(

That was my thought, is there anyone nearby you with a compatible phone who could download the scan app and test scan once to determine if it’s reader or sensor issues. Starting a new sensor to test the reader does seem a waste of supplies, especially if the new sensor shows the problem with your reader and you then have 2 active sensors with no way to read them until you get your hands on a new reader.

Or possibly the device has forgotten the sensor?
Here's an odd one that came up the other day with my Libre app. I use Glimp on my phone but start the sensor with Libre.
12 days in use, the libre app fired up as I was scanning with the icon of the guy with the patch asking me to activate the sensor?
It carried on fine after that.

I’ve done the self test a couple of times , says pass every time but doesn’t say what it has done I.e what’s it actually testing for
 
Hi, @Wurst , libre2 isn't out in the UK yet so I'm not familiar with its quirks yet, but seeing as it uses bluetooth and the red icon is through what looks like some sort of radio wave symbol, I'm wondering whether you've got any other bluetooth devices running in the vicinity which might be interfering with it, and if so, whether switching them off or moving well away from them might make a difference?

Can't find the libre2 manual anywhere - if it came with the reader pack maybe it shows what the icon means?
 

Thanks for the ideas , unfortunately the manual only says it means that the reader can’t communicate with the sensor and offers nothing else. Abbot customer service here is terrible , last time I had a clear sensor problem they just ignored me. After some threats they eventually replaced it:-(

Interesting idea about Bluetooth interference , i will take it into the woods and see
 
I’ve read that you need a libre 2 reader for the libre 2 sensor: is your reader compatible with Libre 2? PS this may be a daft question since you’ve been using the new sensor for 5 days.
Suggest you ring Abbott helpline.
 
can you confirm you are using the Libre 2 - and how you managed to get hold of one! (Ah just checked and you're in Germany - explains it!)

the 'screen shot' to me suggests the bluetooth is switched off - the red line through the communications symbol not the actual sensor itself. I'd be ringing them instead of emailing - Abbott are notorious for slow to non-existent email comms!

Yeah, I was wondering about that too, but as it's the reader that's being used, not a phone, I would have thought it would be permanently on, but who knows without seeing what the settings options are.

Also, even if bt was off, the op says he can't nfc scan with it either and I'm pretty sure Abbott says if it loses bt connection it should still scan.

Looks like libre2 is going to have as many squirrelly glitches as libre1!
 
Ended up calling Abbott who sounded like they were well aware of the described anomaly . Replacement in the post , hopefully the batch doesn’t contain any more anomalous sensors
