Libre Pro Sensor

Open Archana-Balan opened this issue 6 years ago • 11 comments

Hi, I've been working on developing the Limitter device in India. We only have the "Libre Pro" sensors available here which stores complete data of 14 days. The sensor stores 15 minute trend data in one buffer and 14 days of historic data in the remaining memory blocks. I'm able to read the 15 minute trend data correctly. However the sensor NFC tag contains only 256 blocks and can store only 4-5 days of historic data. The remaining data is shown as factory locked. Hence I'm able to read only 4 days of historic data Any suggestions on how I could read the historic data of remaining 10 days ? Thanks !

Hi Archana-Balan, I have also tried using the Limitter device with the Freestyle Libre Pro but was unable to get any values at all into xDrip+! How were you able to get current trend data? I have been able to get my hands on a few sensors from India so am happy to test anything. Thanks :)

Hi @Archana-Balan,

Any updates on how you are going? Did you manage to get this working at all? I'm using Glimp with SW3 at the moment with the Libre Pro, working ok but xDrip+ is a lot better. Thank you very much :)

hi @amit2411amit , I am still using the Libre Pro with sony SW3/Glimp app. I have also built a Limitter and am happy to help with anything. Would like to get it working with xDrip+!

FYI this has now been resolved. I have tested this successfully.

Comments from @keencave Please find the updated LBridge code V1.1.01 here: https://drive.google.com/open?id=1RLxzbgu5Y2GPyd2cUklRKI-TU94QK5Fg Please use the Arduino IDE 1.8.9. The INO need to have the Libre2 library "L2read.zip" installed as a zip library with the IDE. Some minor fixes. Added support for Libre Pro (and Libre H). Any test result welcome. I had only an expired Libre Pro for test.

@daclaw2k I am also working on the LibrePro sensor and not able to find the History section offset and limit. Also not sure of how many bytes the total data is. Can you help please ?

Hi @deepakthakur143, sorry I can't help, I am not a programmer and didn't write the original code. @MarakM60 (creator of droplet) helped decode it, I just sent some raw logs through to him. Have now moved over to a dexcom g5 as it was much more stable for me.

How can i read the data from the Abott Freestyle Libre Pro sensor, Is there some specific protocol that should be used? I identified that ISO15693 is being used, but i tried a few RFID readers for ISo15693 from play store, but that didn't work it was not able to read the data

Can you share how you were able to read the data?
