Introduction to Freestyle Libre 2
Freestyle Libre 2 is a continuous glucose monitoring (CGM) system designed to help individuals with diabetes manage their blood sugar levels. It uses a small sensor inserted under the skin to continuously monitor glucose levels. The sensor sends data to a small reader, which can be paired with a smartphone using the Freestyle LibreLink app. This app allows users to view their glucose data in real-time, receive alerts, and track trends over time. Compatibility with various smartphones is crucial for its effectiveness, as it relies on near-field communication (NFC) and Bluetooth Low Energy (BLE) capabilities.
Hardware Requirements
For the Freestyle Libre 2 app to work, your smartphone must meet specific hardware requirements:
-
NFC Capability: The most critical hardware requirement is the presence of NFC. NFC is necessary for scanning the sensor, which is a crucial step in the process of monitoring glucose levels. The sensor must be placed close to the NFC reader on your phone to establish a connection.
-
Bluetooth Low Energy (BLE): Bluetooth Low Energy is required for receiving alarms and alerts from the sensor. This ensures that users are notified when their glucose levels are outside a set range, helping them take timely action.
Software Requirements
In addition to the hardware requirements, your smartphone must run a compatible operating system and have the necessary software installed:
-
Operating System Compatibility: The Freestyle Libre 2 app is designed to work on both Apple iOS and Google Android operating systems. However, not all versions of these operating systems are supported. Users must ensure that their device is running a compatible OS version to avoid any issues with the app.
-
App Compatibility: The app itself must be installed and updated to the latest version. Abbott provides regular updates to ensure compatibility with new devices and operating systems.
