No data has been shown/included in the app

If no data is shown or recorded in the Glimp app while you're using Pebbles, follow these steps to resolve the issue:

1. Check connectivity: Make sure your Pebbles are properly connected to your smartphone via Bluetooth. The app requires an active connection to receive and capture data.
2. Proper positioning of the thumb: During use, make sure that your thumb is positioned correctly and firmly on the PPG sensor. Improper positioning may prevent the app from receiving accurate data.
3. Clean the sensor area: Make sure the PPG sensor, located where your thumb rests on the left Pebble, is clean and free of dirt or obstructions. Wipe it gently with a soft, dry cloth.
4. Check PPG sensor functionality: Make sure the PPG sensor, located where your thumb rests on the left Pebble, works properly. The small LED on the sensor should blink green. If you don't see the LED lights, try fully charging your Pebbles and/or restarting your device. If the issue is still unresolved, seek professional help from the Glimp support team.
5. Check if a firmware update is required: Open the Glimpse app and check for notifications about firmware updates. If yes, follow the instructions to update the Pebbles firmware and restart the Pebbles and app. Keeping the Pebbles firmware up to date is crucial for optimal performance. Outdated firmware can lead to functional irregularities, including sensor issues.

If you've tried these steps and no data is still displayed in the app, it's best to contact Glimp Customer Service for further assistance. We can provide more in-depth troubleshooting or advice on the next steps, possibly including a warranty claim if necessary.
