Blood sugar control after Hyp

[rebrascora]

So what is the difference between the Libre 1 and 2 then because the Libre 1 warns you when you are heading towards a hypo when you scan. I have read your posts before about this and we were all lead to believe the Libre 2 had alarms which would notify you you were going hypo via your phone, so that it would alert you through the night. If that is not the case then there is absolutely no point.

It has alarms, but if I understand correctly they're not specific (so if you want to know if you're low or high you have to scan). (I don't know if you can enable just (say) low alarms and not high ones.)

@Paulbreen seems to be saying that it doesn't send alarms to your phone at all.... unless I am misunderstanding?

Officially, Libre 2 only uses Bluetooth to send alarms to your phone or reader so you officially have to scan it to get numbers. However, I understand it is possible to hack it to automatically send readings to your phone so you will not need to scan. You cannot use the official LibreLink app but I gave up on that when I discovered apps that allow you to calibrate as I am not 5je same as thefactory setting.
This hack will remove the need for something like a Miaomiao or Bubble to convert the NFC signal to Bluetooth.
I have been using a Miaomiao for the last year and find it so much easier to just look at my phone than to have to scan.

So, I AM looking forward to Libre 2 ... and 3.

Hi Barbara
I thought the same as you but when I got the libre 2’s I could not get it to give any alarms or info for that matter unless I scanned them.
Their communication protocol is NFC which has limited range hence the reason you have to scan
NFC has a range of 4-5 cm at best
For the sensor to ping your phone with data it needs to be on WIFI network with your phone which is not practical or use Bluetooth which the libre 2 doesn’t have, now maybe I’m a dumbass, it could happen lol!! but I used them for over a year and never saw any improvement over the libre 1
The libre 3 has Bluetooth so it can communicate

To be honest, since I don't have a phone which enables LibreLink and just use the reader, I am not that bothered and as I said, my body wakes me up when I need to take action, so I am no longer overly concerned about alarms, but I do love the ability to scan with the Libre whenever I want and use that information, so for me, the original is absolutely fine and I won't be asking for an upgrade.

Hi Heli I think it’s pretty impossible to hack a NFC signal because the hardware will only provide a 4-5 cm distance, currently you have one of the only ways to do it with a maio maio

That’s my experience Barbara, the hardware within the libre2 can’t send signals further than 5-5 cm, that’s why people are using maio maio and bubble repeaters they take the NFC signal from the libre and convert the data and forward it on to your phone in Bluetooth

That's not what Abbott say. They say 20 feet: Libre 2 (US). It also doesn't match anything else I've read about Libre 2, including some comments a while ago from a German user who was mostly complaining that the alarms were a bit useless (the only alarms they got were alarms that the connection was broken, presumably because their phone wasn't quite right).

(And Abbott have this biosensor which looks a whole lot like a Libre 2. It doesn't seem impossible that it's actually identical and it's just the phone software that's a bit different, though I concede that's speculation.)

My understanding (which I cannot verify because I do not have one) is that the Libre 2 uses Bluetooth, not NFC, to send the alerts when too high or too low.

Haha I’m sorry I sent that to the wrong lady but I think it’s applicable to both of you anyway I was trying to say
The functionality of the 2 is not a big step over the 1 but the 3 is a giant leap in comparison to the 1 & 2

You have to scan to see the exact reading with the alarms on libre 2 but it tells you whether it’s a high or low alert and you have set the levels it will have alerted at, so you’ll know the number without scanning

 

[Paulbreen]

I just opened a new libre2 reader and it does have alarms in the setup so I do stand corrected, I never used the reader before so I never saw the alarms setup, I always used my phone

It does seem that you can have alarms if you use the reader but not with a phone
Sorry about misleading any one.
I’ve never tested it so I’m going to stick on a sensor now and see how it works for a couple of weeks

I’m currently using libre 2 on an iPhone and it has alarms.

 

[trophywench]

My main reason for rather wanting it is because others say it is more accurate than Libre 1 - and it would be nice if it was more accurate, since it so very hardly ever has been since I got it.

 

[Paulbreen]

I just finger pricked to calibrate my pump sensor and it was 7.6, first reading from the libre2 I just fitted lol

I give up and I’m going to my cave, this diabetic world is so full of contradictions lol
