There are a number of factors which can cause a visible gap. Many times, the gap will resolve once data flow returns to the app. We've outlined common solutions, below, and if you don’t find a solution among these possible causes contact Customer Support.
Smartphone date and time reset
If you change time zones or the clocks change, your smartphone date and time will automatically reset. The app will show a gap in your glucose trend line, but you haven’t actually lost any data.
What to do: If you change your smartphone date and time to the original setting, the gap no longer appears.
Signal loss
Is your smartphone within 33 feet of the biosensor? Or is a wall or door blocking the signal?
What to do: Make sure your phone is within 33 feet (10 meters) of the Lingo biosensor and you have not force closed the App. Try turning Bluetooth OFF
then ON again. If that doesn't work, try turning your phone OFF then ON again. They’ll reconnect automatically and the biosensor will fill in any gaps in data.
Logged out of app or App deleted
If the app is deleted and re-downloaded, you won’t be able to retrieve old data from your smartphone.
What to do: Your data is stored in the cloud. To access it, just log in to your newly-downloaded app.
Bluetooth off
When your smartphone’s Bluetooth is disabled, the biosensor can’t send data to the app. There’ll be a gap in the data for the duration of the period where Bluetooth is disabled. The biosensor keeps all your data and once reconnected, it will fill any gaps.
What to do: iOS: On your smartphone, go to Settings > Bluetooth. Switch Bluetooth to the “On” position.
Out of range Glucose Reading
If you have a glucose reading below 55 mg/dL or above 200 mg/dL, you will see a gap on your Glucose Graph and will see your data fade out on the Lingo Graph.
What to do: the app is functioning normally, consult your Lingo Graph.
