There are a few different types of errors you might get in your LibreLink app. This article goes through the most common errors and how to troubleshoot them.
Sensor Error, Try Again in X Minutes/Hours
Sensor Error, Try Again in X Minutes/Hours
Problem: Error in LibreLink that says 'Glucose reading not available. Try scanning again in x minutes/hours'
Troubleshooting: Please wait at least 12 hours after applying your sensor to give it enough time to calibrate.
The sensor needs 12 hours to calibrate, and this message might appear. Please wait until the calibration period ends, and you should be able to scan normally. If you keep getting the same error after 12 hours of installing the sensor, please let us know. It might take your sensor up to 48 hours to read accurately, so please wait to ensure enough time has passed to reach accuracy.
If you have had the sensor for more than 48 hours, the reason for this error can be that your values have been erratic and the sensor cannot keep up with the variation. Please wait the indicated time and try again.
Check sensor

Problem: Error in LibeLink says 'Please check your Sensor. If it is loose from your skin, please remove the Sensor and start a new one. If it is applied properly, try starting Sensor again.'
Troubleshooting: This usually means the filament is not properly placed under the skin. If this error appears after a few days of wear, it likely means the filament has been ripped off from your skin. Unfortunately, it cannot be put back on and thus you'll need to replace the sensor.
If you get this error when inserting the sensor, you can try to scan it again. If the error persists, it means the sensor likely is not installed correctly and will need to be replaced.
Sensor already in use
Sensor already in use
Problem: Error in Librelink says: The Sensor you just scanned was started by another device and cannot be used.
Troubleshooting: This can happen if you try to scan the sensor with a phone that the sensor was not set up with. A sensor can only be used with one device, the one it was set up with.
Scan timeout
Scan timeout
Problem: Error in LibreLink that says Scan Timeout / The sensor was not found. Scan again.
Troubleshooting: This error appears when the phone does not connect with the sensor. This is likely due to the phone not being close enough to the sensor for long enough to receive the data.
The sensor uses the same NFC technology as is used in contactless payments, so you can think of scanning the sensor like scanning a payment on your phone. The NFC reader location on the phone differs between different phone models, so you might want to try scanning with the top part, and then the middle part of your phone to find out which part gets the scan to read.
New Sensor Found
New Sensor Found
Problem: LibreLink says Starting a new Sensor will end the Sensor you're currently using. Would you like to start the new one now?
Troubleshooting: This happens if you scan a new sensor before the old one has ended.
Regional Sensor Incompatibilities
Regional Sensor Incompatibilities
Problem: The sensor is from a different region than the LibreLink app you have downloaded. This should only happen if your app store is not registered to the location in which you are buying the sensors.
Troubleshooting: Change the App Store on your phone to match the region that the sensor is from.
