# Smartwatch won't connect to smartphone

# Kardena smartwatch won't connect to smartphone

Is your Kardena smartwatch not connecting to your smartphone? In most cases, the connection can be restored with just a few steps.

> ℹ️ **Note:**
> Make sure the smartwatch and smartphone are right next to each other during setup.

## 1. Check Bluetooth

First, check the following:

* Bluetooth is switched on on your smartphone.
* The smartwatch is switched on and sufficiently charged.
* The smartwatch is in close proximity to your smartphone.

Switch Bluetooth off on your smartphone, wait a few seconds, then switch it back on.

## 2. Connect via the app

Open the app for your Kardena smartwatch and start the device search there.

> ⚠️ **Important:**
> During the initial setup, **do not pair the smartwatch directly via your smartphone’s Bluetooth settings**. The connection should be established via the smartwatch’s app.

## 3. Remove an existing Bluetooth connection

If the smartwatch has been connected before:

1. Open the Bluetooth settings on your smartphone.
2. Find your Kardena smartwatch.
3. Select **"Remove Device"**, **"Unpair"**, or, on an iPhone, **"Ignore this device"**.
4. Restart your smartphone and smartwatch.
5. Open the app.
6. Search for the smartwatch and reconnect it.

## 4. Check app permissions

Depending on your smartphone, the app may require various permissions, for example for:

* Bluetooth
* nearby devices
* notifications
* background activity
* location access, if applicable

Check your smartphone’s settings to ensure the required permissions are enabled.

## Still having problems?

If necessary, reset the smartwatch to its factory settings and then carry out a new setup.
