Hello all,
Very Beginner in BLE
Need Clarification in BLE with FreestyleLibre
What is FreestyleLibre – FreestyleLibre is continuous glucose monitoring in our body.

    Working of FreestyleLibre
    1. Fixed FreestyleLibre device in arm
    2. The Official App for FreestyleLibre is installed on Android devices and using NFC on Android devices to activate FreestyleLibre device takes 1 hour to activate
    3. After FreestyleLibre device activation data is automatically received and viewed in the Android app
    Need More Clarification Youtube https://www.youtube.com/watch?v=4c4t_4-5m8M&pp=ygUWZnJlZXN0eWxlIGxpYnJlIDIgVUFFIA%3D%3D
    
    My doubts
    1. Android device fetches data from the device or Data pushing to the Android device
    2. Why this app is not detected in Custom App (flutter_blue_plus plugin used) and that time I received data from a device in the Official app
    3. If the device pushing data to an  Android device how the device is connected to an Android device (My thought while an ID is written while activating FreestyleLibre)

Need Clarification about BLE with FreeSyleLibre2 Device and expecting technical also
