Diabetic Patient New to Github and android
First thank you for this great app that will help me a lot.
Iam a diabetic patient and i would like to use this app to get blood glucose data from my sensor to my android mobile.
I would like please to understand how can i install your application on my mobile phone.I have download the Zip file but then i don't know what to do with .
Thank you !
You have to download the apk. An apk in an installation file. Download it here (click "View Raw"): https://github.com/vicktor/FreeStyleLibre-NFC-Reader/blob/master/app/FreeStyleLibre/app/build/outputs/apk/app-debug.apk You may have to enable an option to allow 3rd party apps.
OK thank you very much ! i found a tutorial to install an .apk files that explain how to allow 3rd party apps ) http://papidroid.com/2013/12/12/how-to-install-apk-files-on-your-android-phone-or-tablet/
An other last questions please, i would like to know if there is an Iphone version of this App. And if yes how to install it too please. Is there an article that i can read to understand how to use the apps with my sensor after the apps are installed?
Thank you very much for these great apps and for your help !
Well an iPhone app is not really practical for now, since the app is not made for a real world situation. It's not as easy to install a developer app on an iPhone as on Android. iPhone development (or at least the app store with witch you have to publish your app if you don't have a jailbreak) might come, but not now.
About the app: You just hold it against your Pad and it scanns it. You have to have NFC enabled. The app shows the current calculated value on the bottom along with all the data the sensor sends. (Note: I did not manage to get close to the real world glucose values. Since there is a new algorithm it might be more precise in the future) There is also a saved textfile which you can process with python to show some glucose values of the last 8 hours.
See the wiki for more information about the calculations.
I have installed the app. The figure 116 is coming back but the reader is showing 5.5. Any ideas about the corolation.
I guess 5.5 is mmol/l? That's around 100 mg/dl. The figures from the app do not match exactly the values from the reader. There is still a lot of work to do as the tag stores raw sensor data that need to be interpreted.
Please can the app have a large figure on screen in mmol. then store a string of them so that last value is shown.
I guess the reader I have is doing something with the values based on past readings.
The issue here is, that in different countries different units are being used. you need to calculate: mg/dl x 0,0555 = mmol/l mmol/l x 18,02= mg/dl
But since the values you gain are far from being useful in a real world scenario it may not be important. I might have a look into the code so it creates a second output with the mmol value.
many thanks.
what do you think about writing some code to mimic what the firmware in the reader does.
assuming it has the same values to work on as returned by your app, it must be averaging some of the previous values.
so if I scan say ten times in ten minutes and then add a conversion factor I might get the same value on screen as the reader is showing.
Hi, I am working on it, you're welcome to join. More info you can get on this page: https://github.com/vicktor/FreeStyleLibre-NFC-Reader/wiki/Decoding-of-tag-data I also made some desktop software for anlaysis. You can find it here: https://github.com/davidweisgerber/taganalyzer
Please keep in mind, this is a proof of concept, not ready for usage yet...
Its very important, never use this app as your default reader! It is only for testing purposes
And welcome! feel free to join us!
understood.
btw what happens at the end of the sensor life. I know it keeps transmitting but do the internal ring buffers get overwritten.
sensor works fine about 15 days, after, will stop record new glucose values.
how about a reset code to write a new sensor id and wipe the data.
is the sensor id read only.
At least it is not my goal to prolong the life of the sensor. At the moment we read only from the tag (we did not even try to start it). I would be happy if we got a fully working android app for reading the tag so I do not need to carry the reader with me...
I agree a working app would be great.
just interested to see if anyone had reset the tag.
BTW how do I know when a new version of the app is ready to be installed so I can test and provide feedback.
Yesterday something strange occured to me, after reading sensor with the app, the official reader didn't allow me to read for 10 minutes, showing something like "Read error, wait 10 minutes and try again". I thought I was in a trouble, because my sensor was 1 day XD. I hope that it can help you to know what really happen when the official reader reads the sensor, I think it's not just read only ;)

With official Reader, it seems that there are a max readings allowed. Try it, make a lot of reads with FSL Reader.
@fnando08 WTF!!! I had the same problem yesterday, too and it was the only time I saw it...
Hi, Thank You Very much for this Project! I installed app but when I try to scan read two error: "Error reading Nfc" "Error opening nfc connection"
The NFC connection in General set up is activated Somebody help me please?
@vicktor @davidweisgerber Sorry to awaken an old issue, but have ye figured out if extending the sensor beyond 15 days is possible? I've got a great setup going with Glimp S, LibreAlarm, xDrip+ and a Sony Smartwatch 3. The last thing on my todo list is extending the life to make it a little cheaper 💸 Interested to hear any thoughts on how the sensor manages to limit itself to 14 days. I assumed it was only abbot's software, but LibreAlarm suddenly started repeating itself this morning, and I've left ordering a new sensor too late 😭
