Another Libre newbie with queries

Really helpful pdf thanks! Have been looking into the diabox app since Jaylee recommended it on another thread. So far been using libre 1 with libre view app and been happy but thinking forward to my prescription changing to libre 2.

Can you be connected to more than one Bluetooth device at the same time (one being the libre 2 sensor) and get the alarms via the diabox app? Eg if driving and connected to handsfree in the car via bluetooth, would the diabox app still be able to get the sensor readings from the libre 2 and alert you as per your settings? Or if using a Bluetooth headset/headphones (need to for work) would the sensor still be able to communicate with diabox on your phone while the same phone is connected to the headset? Google tells me Bluetooth 5 can do this, and my phone has this. But I don't want to request a script change to libre 2 and then not have access to the alarms while at work or driving, for example. The beauty of the libre 1 is using my phone, so I also don't want to just use the libre 2 reader.

Sorry for the long question!
 

Actually yes... you can have your phone connected to more than one Bluetooth device at the same time. So for example my phone is always connected through Diabox to Libre2, and it is connected to car infotainment unit when driving, my smartwatch at all times as well, and I connect it to speaker every now and then through Bluetooth. Alarms on Diabox work as normal even with multiple Bluetooth connections atleast for me .
 

Thank you. Reading low has happened with 2 sensors so far; I think its me that needs to be replaced.

So that is a yes? If the sensor indicates 1.8 mmol/L then xdrip will report something similar (uncalibrated).I am using the Libre reader as my phone doesn't support Librelink. I thought it might be the reader imposing the 'Low' display and doing the processing (algorithm). I will have to get a new mobile to use xdrip/diabox.

What exactly is the data sent over the nfc channel from the sensor? I understood it included the last 15 1 minute readings.
What is the process xdrip uses to calibrate the sensor data?

Bought a Libre and 2 sensors I thought a couple of months ago but just checked the use by date ...oops seems to say 30th Sept 2020.. Do I have some rather expensive ornaments...?

You could always try one and compare it to finger pricks for a while - they all run either low or high anyway, so you might find it’s just out by more than usual but gives an idea of overall patterns?

I guess I can stick one on when I get the Gluco Navvi strips and do a 3 way test with the Tee2 .. sounds like a plan..!

I would try it. I think the 'use by' has more to do with the expected life of the battery inside it.

Hi,

You say you sleep on your left, and have the sensor on your left.
This means there is a possibility that the 'huge night time low' may have been a 'pressure low' caused by lying on the sensor.

I sometimes get real lows at night (tend to look like a V on the graph), with a rebound that is a bit higher than my usual night time graph line.
I also sometimes get 'pressure lows' from lying on the dratted thing. When this happens the graph line plummets, runs along flat for a bit, and then rises (when I roll over) back to carry on as usual.

So the two different 'lows' are very easy to distinguish.

Hope that helps!

Hi Brunneria,

Thanks for this, really useful info. I have had two nights with the sensor now. The low glucose alarm woke me both nights and I sat up and tested. They both look more like a V shape. That being said, it might be a better idea for any future sensors to be on my right arm.

P
 

if they are waking you up, then the quickest way to get a second opinion is to do a prick test at the time. just make sureyou do prick tests at other times too, so you know how far the Libre is usually out of sync.
Hope you get a clear answer.
 
Thank you p62
Yes I have been very strict with low carbing so far, due to the help and support on here. Being 'just a type 2' I do have life easier than you and the others out there who have to constantly monitor. I vote for CGMs for all diabetics irrespective of type, location or control.
Viva cgms!
 
Wow! Brilliant, and there's me been been picking up bits from others posts and not getting the full picture! This is great thank you.

Proofreading wise there's one "sesnor" and a little more explanation about diabox would be useful

Hi,
Personally, try using the Daibox app with it. You may find the accuracy closer to your strips than the interpritation of the algorithm on the Libre link app?
& as I've just discovered, you can calibrate it too...

At a guess it could also be the shelf life on filament with the sensor that interprets readings from the interstitial fluid?

Out of date sensors have worked fine for me, but I've seen reports from other people that they don't work at all.
 
After managing to knock off my Libre 2 and having to find myself another one, does anyone else have an alternative site? I know that Abbots recommend the upper arm, but bra straps cause problems there because I have to wear them tight. Any suggestions? I would be grateful.
 
Hi, mine goes on the back of my arm, about half way down. I haven't had any issues with it there. To put it on I hold my arm straight out in front of me, and the my other arm can reach the under side of the back of my arm. Hope that helps a bit? If you think it was a adhesive issue then libre will replace if you've followed their instructions, but not if you say you knocked it. I find mine stick like limpets! Have got them caught on things (like tighter tops, bag straps etc) loads but it has never been enough to pull one off, not even a bit off.
