Libre 2 and 3

[everydayupsanddowns]

Even without the rest it's a cheap CGM with a small sensor (and no transmitter). That seems sellable on its own. But yes, they'd be daft not to also be thinking ahead to closed loop systems, and I imagine calibration is part of that.

As a self-funder the transmitter is a significant annual cost factor for me.

Of course the 3 must have some sort of transmitting/receiving technology, otherwise it wouldn‘t be able to get the sensor data from one element of the system to the other... but it’s exciting to see that no clip-in / rechargeable / expensive / short shelf life additional element is needed as part of Libre3

From adverts/announcements with a different brand name (which temporarily escapes me), they're selling what looks a lot like the Libre 2 to sports people and saying it gives regular (once a minute, I think) glucose readouts to a phone app. So my guess is the Libre 2 can do this but hasn't got regulatory approval for some reason so it just offers alarms.

But yes, it's a bit surprising that they can apparently get that much battery life. Maybe it's Bluetooth LE and Dexcom, etc., were earlier to had to use more energy requiring older Bluetooths, and didn't have much incentive to update to using LE.

I was misremembering (or maybe when I saw it the advert hid Abbott and Libre a bit more):

@Bruce Stephens I think you are thinking about Libre Sense (https://www.libresense.abbott).
This was developed in collaboration with Supersapiens (https://www.supersapiens.com/) who provide the sports related analysis app.

According to my diabetic team Bluetooth seems to be the comms protocol for the libre3 because of apples reluctance to free up full NFC protocol in the iPhone, a little bit hearsay but these guys are not the typical diabetic team you find in the UK, they are heavy involved with tech manufacturers so they are normally right

I don't buy it. NFC's designed for really short distance purposes (a few cm, basically nearly touching). Bluetooth is the more usual mechanism for this kind of thing (a few metres).

(I can believe not needing NFC will make dealing with Apple easier but I'd guess that's a happy coincidence rather than the driving motivation.)

I hear Apple are doing something in the diabetic world and this may be the reason why they are not opening the NFC capabilities yet, for the application of pump and sensor comms NFC is more than capable to fit the application and can be more secure than Bluetooth. Also NFC is in the source code of Apple devices for a couple of years but heavily restricted, android however is completely open for developers I develop apps for mobile devices on occasion and the android world is a lot easier than the Apple world because of their need to control
