To use your Libre as a CGM that is getting new BG values every 5 minutes without having to scan the sensor, you need to buy an NFC to Bluetooth bridge (commercially available devices, based on the obsolete LimiTTer project).
:class: warning
Verify the bridge and the app you want to use are compatible with your sensor.
Some bridges are still available on the market:
- MiaoMiao Reader (version 1, 2 or 3) also available on AliExpress.
- Bubble / Mini / Nano from European vendors (BubbleShop) or for Russian users here. Also available on AliExpress.
- Atom for Russian users.
- xDrip+ supports Miaomiao, Bubble, Blucon, Atom and LibreAlarm.
- You can safely download the latest APK (stable) unless you need recent features, in which case you should use the latest Nightly Snapshot.
- Follow setup instructions on xDrip+ settings page.
- You also need OOP2 for Libre 1 US (and Libre 2 EU).
- Select xDrip+ in ConfigBuilder, BG Source.
- Diabox is the vendor app for Bubble.
- Install Diabox. In Settings, Integration, enable Share data with other apps.
- Select xDrip+ in ConfigBuilder, BG Source.
