Hi! I understand that your phone, Bluetooth, and watch all indicate they are connected, but the HanoFit app says it's not connected and won't refresh. Let’s see if we can get this sorted out for you.

To clarify first, is your watch or device paired via Bluetooth directly through your phone’s settings, and are you using the latest version of the HanoFit app on your Windows 10 system? Also, is the issue happening only on your phone or on your PC as well?

Meanwhile, here’s a step-by-step approach we can try:

1. Restart All Devices: Power off your phone, watch, and Bluetooth device fully. Then turn them back on. Sometimes this resets communication channels.

2. Force Stop and Clear Cache on HanoFit App: (If using a phone) Go to your phone's Settings > Apps > HanoFit > Storage and select Clear Cache. Then reopen the app.

3. Forget and Re-Pair Bluetooth Connection: Head into your phone’s Bluetooth settings, “forget” the watch or device, then re-pair it fresh. This can resolve hidden connection bugs.

4. Check App Permissions: Make sure the HanoFit app has necessary permissions allowed, especially for Bluetooth and Location since some devices require location access for Bluetooth scanning.

5. Update or Reinstall HanoFit App: Make sure the app is updated to the latest version from your app store or official site. If the problem persists, uninstall, then reinstall the app.

6. Enable Bluetooth and Location Services Before Opening the App: On some devices, the app needs these services active from the start to detect your watch properly.

7. Check for Interfering Connections: If multiple Bluetooth devices are connected simultaneously, try disconnecting others and then open the HanoFit app.

If these don't work, we might want to explore Bluetooth settings deeper or potentially check if there are software updates for your watch or phone. Could you please share which phone model and watch you are using? That will help me tailor the instructions better.
