Libre - start new sensor - question

In Response said:

There is no button on the app because you do not need to press a button to scan: you just need to scan the sensor via NFC.
My app looks exactly the same (but I don't have a Libre to scan).

I don't think it is possible to check if the sensor is working until it has been applied (and the battery connection made).
I am confused what you are trying to do before applying the sensor.

I don’t understand. On my app there is a blue button which says scan. Press that then I get a pop up which says ready to scan. Then I can scan using nfc. I can’t scan with nfc until I have pressed that first button. How do you do that?

I agree the sensor cannot be scanned using nfc until it has been applied.

No not quite. I used to use Libre 1 and then because of skin rashes I stopped. Now the Endo' wants me try Libre 2 and has given me a sensor and the on-line (Zoom) training session. I got the App from Google play but it doesn't look like the user manual.

Just apply and scan it, looks all good!
I think you're overthinking this.

Usually it's impossible to download the app on an incompatible phone, so it'll very likely work just fine.
And if not, just give Abbott a call and they'll replace the faulty sensor.

Ok that's interesting, - whoever was on the other end of the Zoom call (at the hospital) specifically said to "press the blue button"

I have never needed to press any button before starting a sensor. Maybe it's a small difference between Apple and and android or such.

No way to find out but to finally apply that sensor and give it a try!

I am trying to make sure that the App is working - but from what you've said, I should just try it.

Whoever was on the call may have had a moment of confusion. For my dexcom I have to press a blue button. For Libre I used to just scan it

You can’t check sensors before they’re applied. You also need to make sure NFC is enabled on your phone. If you have your phone in a case this may be blocking the signal. My nfc scanner appears to be on the back of my phone, not the screen, so try that too. You need to keep the right part of the phone on the sensor for a few seconds. Mine vibrates twice when scan is complete. They really shouldn’t issue these things without giving you the education to use them properly. May I also add that there are short courses on how to use the Libre sensors on Abbott’s website. I’ve also found them veey helpful on the phone.

Were they talking about starting the sensor with the actual reader? This may be where the ‘blue button’ idea comes from.

How old are your phones? I had a similar problem but updated my phone, clicked on the link from Abbot to install the app and applied the Libre. It won’t connect if you haven’t attached it or completed the profile section on the app. Hope that helps!
