Your FreeStyle Libre 2 app§ is likely trying to reconnect with the Sensor via Bluetooth®. Scanning the Sensor utilizes your device’s NFC, not Bluetooth®, to get a current glucose reading and this function is independent from your device’s Bluetooth®. Please wait a few minutes for the Bluetooth® to reconnect your app to your Sensor.
§The FreeStyle Libre 2 app and the FreeStyle Libre 2 reader have similar but not identical features. Finger pricks are required if glucose readings or alarms do not match symptoms or expectations. The FreeStyle Libre 2 sensor communicates with the FreeStyle Libre 2 reader that started it or the FreeStyle Libre 2 app that started it. The FreeStyle Libre 2 app is only compatible with certain mobile devices and operating systems. Please check the website for more information about device compatibility before using the app. Use of FreeStyle Libre 2 requires registration with LibreView.
