New sensors Libre….

(English version below)

Last year (2018) new types of sensors Freestyle Libre-Libre 2, Libre Pro, Libre H and Libre US 14-Day appeared on the market. It's good and bad. Well-because the development of technology and increasing its availability is good for the diabetics community, and bad-because these new sensors do not support currently available solutions allowing for the self-construction of CGM systems.

Practically since their emergence-an international team of developers creating applications such as Spike, xDrip, Nightscout, loops closed in which this team I have a pleasure to attend from the beginning-began work on their decoding and Enabling them to cooperate with them.

The work ended in the last days (except for the Libre US 14-day sensor, which is still ongoing). Fortunately, we managed to solve all the problems with these new sensors. Unfortunately-it is necessary to replace the internal software in the intermediary devices, ie in MiaoMiao, BluCon, GNSentry, my transmitters, etc. Some of them allow this update by the user, others will need to refer to the manufacturers.

At the present time, we are talking to all manufacturers about the necessary changes and on what rules these changes will be made.

In relation to the manufacturers, we have adopted simple rules-the same for all:

  1. Existing in firmware protocols-remain unchanged
  2. Each manufacturer is obliged (if he wants his device to work with new sensors) introduce a new protocol "bleDiab-L" which the specification receives from us. This is a very simple transmission protocol and adapting the current software should not take more than 1 working day for the manufacturer.
  3. After the introduction of this protocol the manufacturer has to provide us with several such modified devices to check, test whether everything is OK.
  4. All existing producers have not participated in any costs or activities related to our work-we provide them with a new protocol without any effort on their part. Only if they wanted to apply it in their own applications-other than xDrip, Spike, Glimp – we require them to make a financial grant to the Nightscout Foundation in any of their established values.

All the work performed by the development team was and is implemented as a "non-profit" action. None of us in this respect received any gratification and the whole result is for the open-source community available free of charge.

Here, I would like to thank all the projects involved: programmers, people who gave us test sensors, application testers.

Last year (2018) new types of Freestyle Libre-Libre 2, Libre Pro, Libre H and Libre US 14-day sensors appeared on the market. This is both good and bad. Good-because the development of technology and increasing its availability is good for the diabetic community, and bad-because these new sensors are not currently supported in the available solutions allowing for the independent construction of CGM systems.

Practically from the moment of their appearance-an international team of programmers creating applications such as Spike, xDrip, Nightscout, closed loops in which I have the pleasure to participate from the beginning-began work on their decoding and enabling Cooperation with those sensors.

The work ended in the last days (with the exception of the Libre US 14-day sensor, which is still underway). Fortunately, all problems with these new sensors have been solved. Unfortunately-It is necessary to replace the new, updated internal software in intermediary devices, i.e. in MiaoMiao, BluCon, GNSentry, my transmitters, etc. Some of them allow such updating by the user, others will have to be sent back to the manufacturers.

At the moment-we are conducting talks with all manufacturers regarding the necessary changes and on what terms these changes will be introduced.

We have adopted simple rules for manufacturers-the same for everyone:

  1. Protocols existing in the firmware-remain unchanged
  2. Every manufacturer is obliged (if he wants his device to work with new sensors) to introduce a new "bleDiab-L" protocol, which he receives from us. It is a very simple transmission protocol and it should not take more than 1 business day for the manufacturer to adapt the current software.
  3. After entering this protocol, the manufacturer is to provide us with several modified devices to check, test if everything is OK.
  4. All current manufacturers have not participated in any costs or activities related to our work-we provide them with a new protocol without any expenditure on their part. Only if they want to apply it in their own applications-other than xDrip, Spike, Glimp-we require them to make a financial grant to the Nightscout Foundation in any decided by them value.

All the work carried out by the team of developers has been performed as a "non-profit" activity. None of us have received any gratification for this and the whole result is for the community creating open-source software available free of charge.

At this point, I would like to thank everyone involved in this project: developers, people who gave us sensors for tests, application testers.
