Your patient will need to decide which device they want to receive their alarms on. This is an important first step as they can only receive alarms on the device they start their FreeStyle Libre 2 sensor with.
Once your patient has started their FreeStyle Libre 2 sensor with the FreeStyle LibreLink app,◊ they can follow the instructions below to receive alarms.
If your patient wants to receive alarms on the FreeStyle Libre 2 Reader, see the FreeStyle Libre 2 system user manual for information about setting up and using alarms.
To receive optional glucose alarms on their smartphone, your patient needs to make sure they have notifications enabled for the app. If they didn't enable all notifications and permissions during app set up, how they do it now depends on their phone's operating system.
Do not force close the App.
Check to make sure that you have the correct settings and permissions enabled on your phone to receive alarms.
Enable Bluetooth and allow the App to access Bluetooth.
Allow Notifications for the App. Turn on Lock Screen and Banner alerts, Notification sounds and general phone sounds or vibration. Make sure not to turn on any features or modify phone settings that may interrupt the presentation of notifications.
Turn off Do Not Disturb mode or select to turn on Override Do Not Disturb in your alarm settings. Do this if you want the alarm to always play a sound and appear on the lock screen even if your phone is muted or Do Not Disturb is on.
Note: You must accept the App's permission request for Critical Alerts to use this feature. You can also enable the Critical Alerts setting directly from the App's notification settings.
Enable Bluetooth and allow Nearby Devices permission for the App (Nearby Devices permission is required for Android 12 and above).
Do not force close the app.
Allow Notifications for the App. Turn on Lock Screen notifications, Notification sounds, Channel notifications, Sound and Pop-up notifications, and general phone sounds or vibration. Make sure not to turn on any features or modify phone settings that may interrupt the presentation of notifications.
Turn off Do Not Disturb mode or manage the settings for your alarms to override Do Not Disturb. Override Do Not Disturb functionality depends on the phone model and Android operating system version you are using.
Allow Alarms & reminders permission for the App. This permission is required for Android 12 and above.
Turn off Battery Optimisation for the App to allow the App to run in the background and ensure that you receive alarms, even when your phone has low battery. You may need to add the App to the list of apps that will not be put to sleep.
