Possible new serial number for Libre2

[aslepykh]

I suppose new serial number for Libre2 (RU region) is released. Can't pair it with xdrip+ (3e86af7-2023.11.14) on Pixel 5.
OOP2 (8a0ee8f-2022.06.10) is installed also.

Libre2 (RU) was activated on another device (iPhone 13 Libre2 App). This device was disabled during pairing attepts with Pixel 5.

I converted the issue into a discussion since you seem to have missed our request not to open an issue.
Let's find out exactly what's going on before turning this into an issue.

[aslepykh]

My bad!
What additional information should I give you about this problem?

@PhilTU

[PhilTU]

OOP2 (8a0ee8f-2022.06.10) is installed

That's old. You want May 2023 version.

May not resolve it but let's isolate that first

[aslepykh]

So I found and installed OOP2 (27da3f5-2023.05.25).

Issue isn't resolved

[PhilTU]

Is error log identical - flipping to Libre 1 as not recognised?

See Tzachi response below.

Libre 2+ and RU version are like US Libre 2 that we haven't been supporting.

[aslepykh]

Yeah, error log is identical. Trying out Tzachi recommendations right now

Here is a new version of xdrip: https://drive.google.com/file/d/1i2n6zNFrNGcaRSVOO58dX7jzuEWfRx2g/view?usp=sharing
And oop2: https://drive.google.com/file/d/1PbQQoY_KfOrjOboLgKrp4aQy3HZzvZRf/view?usp=sharing

You need to create a backup of xdrip settings and DB and then restore them. You will not be able to restore to google drive, so please backup them up manually.

Please install them and let me know how it goes. I'll soon be offline for 24 hours but hopefully it will work.

[aslepykh]

So I reinstalled both apps. Here's log

I tried multiple times scanning, same result

[tzachi-dar]

I'll take a look tomorrow, but it might be a new sensor and not just a new sn. Does the box say libre 2? בתאריך יום א׳, 28 באפר׳ 2024, 19:02, מאת aslepykh ***@***.***

[aslepykh]

Yes, it's Libre 2 for sure.
I'll be waiting, thanks!

[PhilTU]

From elsewhere I was aware there is an issue with a modified L2 sensor for Russian market as Diabox dev is "working on it".

A haha guidos has written at the same time as me.

[aslepykh]

Does that mean that there is no simple solution?

[parapenT1sta]

Libre 2 C6 was added to xDrip4iOS: JohanDegraeve/xdripswift@549647a

[tzachi-dar]

I'll try to take a look tonight, but since I'm traveling tomorrow, this might have to wait.

[gui-dos]

Not only is the Libre 2 RU a “Gen2” device but, like in the newer US 2 2B models, the native P1() and P2() DataProcessing methods now require a further random token array. See: j-kaltes/Juggluco@9ff9c9d

[PhilTU]

Does that mean that there is no simple solution?

Exactly. We don't have support for US or Canada Libre 2 sensors (or Aus / NZ) so Russia is joining that list (UK too is about to get Libre 2+ with same issue).

[gui-dos]

The new Libre 2+ US has another sensor type code, 2C…

[aslepykh]

Got it.

I have managed to get it to work with Juggluco, but it has some shortcomings compared to xdrip+, but it works for me.

Thanks for the help and clarification!

I have created oop2 version for the c6 libre2.
Please note that we are using the first 3 numbers so I might need more information for this. Right now it is 0xc60930

Do we need a PR for this?

[PhilTU]

I have a Libre 2+ sensor (UK) arriving today and will use the above test version with it.

these are going to be the standard Libre 2 offerring in the UK from next month via prescriptions and are already the retail version online from Abbott. It has a 15 day life - not sure if that needs to be accommodated explicitly in xDrip+

[gui-dos]

The wearDuration in minutes of a sensor is stored in the FRAM[326]/[327] locations: the UK models are not using the Gen2 protocols so the current decrypting methods should still work since the memory layout has not been changed.
