Hi there! I see you're experiencing signal loss issues with your FreeStyle Libre 3 sensor. Let’s work together to get that fixed. Could you tell me when the signal loss happens? Is it intermittent or continuous? Also, are you using the sensor with your smartphone app or a reader device?

Meanwhile, here’s a step-by-step approach you can try to restore the connection:

1. Stay close to the sensor: Keep your smartphone within about 20 feet (6 meters) of the sensor, with no physical obstructions in between, because distance and barriers like walls can interfere with Bluetooth signals.

2. Scan the sensor manually: Try opening the FreeStyle Libre 3 app and scanning your sensor again to re-establish the connection.

3. Toggle Bluetooth: Turn the Bluetooth off on your smartphone, wait about a minute, then turn it back on. This can refresh the wireless connection.

4. Restart your phone: Power off your Android device and turn it back on. Sometimes a simple restart resets communication and resolves temporary glitches.

5. Check for power optimization settings: Since you’re on Android 10, ensure that the Libre 3 app is excluded from any battery or app power optimization settings that might be limiting its background activity. You can check this in Settings under Battery or Apps.

If after these steps you still see signal loss, let me know what you have tried and how long the issue has been occurring. We can then look into advanced troubleshooting or sensor status.

Does that help get started? Let me know if you want me to walk you through any step!

Here’s a detailed guide from Abbott on restoring connection after signal loss if you want to check it out too 1

It said it was time to upgrade the app so I did and it worked at first but now it loses the signal

Thanks for letting me know that the signal loss started after you upgraded the FreeStyle Libre 3 app. That’s useful info. Sometimes after app updates, a few settings can get a bit off or the system needs a small reset to sync properly.

Since it worked at first after the upgrade but now loses signal again, let's try these steps specifically considering the update:

1. Close the app completely (remove it from your recent apps) and reopen it. This reloads the app fresh.
2. Restart your Android phone to ensure any temporary glitches or Bluetooth service hiccups are cleared.
3. Toggle Bluetooth off and on on your phone. Turn it off, wait a full minute, then turn it on again to fully reset the connection.
4. Check that the Libre 3 app is excluded from battery optimization, which is common on Android 10 and newer and can limit background Bluetooth connections. Go to:
Settings > Apps > FreeStyle Libre 3 > Battery or Power Management and set it to "No restrictions" or "Don't optimize."
5. After these steps, stay within about 33 feet of the sensor, ideally closer with no physical barriers (walls, thick clothing) as the Bluetooth signal range is about that.

If signal loss persists, it might be good to check if other apps or Bluetooth devices are causing interference. Also, waiting about 2-4 minutes after getting back into range can help the sensor reconnect automatically1.

If these efforts don’t resolve it, your sensor could possibly need replacement, or there could be a bug with the app version that Abbott is aware of. In that case, we could explore contacting Abbott support for a sensor check or further app troubleshooting.

Did you try any of these specific steps after your update? How long after the update did the signal loss start? That can help me guide you better.
