# iPhone – Connection issues and missing notifications

# iPhone – Troubleshooting connection issues with the Kardena smartwatch

Is your Kardena smartwatch failing to connect properly to your iPhone or not displaying notifications?
Check the following settings.

## 1. Check Bluetooth

Go to:
**Settings → Bluetooth**
Make sure Bluetooth is switched on.
Then open the smartwatch app and check the connection status there.

> ⚠️ **Important:**
> When setting up your smartwatch for the first time, don't connect it directly via the iPhone's Bluetooth menu. Complete the setup using the dedicated app instead.

## 2. Check the app’s Bluetooth permissions

Open your iPhone's settings and check whether the app you're using is allowed to access Bluetooth.

## 3. Check notifications

Open:
**Settings → Notifications**
Make sure that notifications are enabled for the apps you want.
Then, within the smartwatch app, check which apps are set to send notifications to the watch.

## 4. Check background refresh

Check under:
**Settings → General → Background App Refresh**
whether background refresh is enabled for the app you're using, provided that the app requires it.

## 5. Consider focus modes

Active focus modes such as:
* Do Not Disturb
* Sleep
* Work
* custom focus modes
can affect which notifications are shown.

Check, therefore, whether a Focus mode is active.

## 6. Reconnect the smartwatch completely

If problems persist:

1. Remove the smartwatch from the app.
2. Go to **Settings → Bluetooth**.
3. Tap the information icon next to the existing entry, if present.
4. Select **Ignore this device**.
5. Restart your iPhone and smartwatch.
6. Open the app.
7. Reconnect the smartwatch.

> ℹ️ **Note:**
> For Kardena models with Bluetooth phone functionality, additional Bluetooth connections may be required for the phone function, depending on the model.
> 💡 **Tip:**
> If the smartwatch is connected and synchronising data, but only notifications are missing, you should first check the notification and app permissions.
