How to fix Bluetooth that is not working (Smartwatch)

If you cannot pair your (smart)phone or tablet with another bluetooth-capable device (e.g. computer, tablet, bluetooth speaker/headphones, etc.) restart the mobile device. After it turns on, you should be able to pair it with another device, provided that its bluetooth feature works.

If you are not sure how to restart your mobile device, check out the don't know how to restart my device guide.

Maybe restarting your device is all you need in order to make the Bluetooth work again. All you need to do is to turn the device(s) off and back on, after a few minutes.

If you restarted your device, but the issue persists, check out the other solutions.

Maybe your device's Bluetooth feature works, but your device is out of range of the other Bluetooth device. The range can vary from 3 to 100 metres, depending on your device. If you are not sure what range your device can cover, search for its bluetooth specifications on the Internet.

If the device's battery is empty, you might not be able to use its Bluetooth feature, because of the power saving mode.

Make sure that the device's battery is charged (or at least charged up to 25%) so that you can activate and use the Bluetooth.

If your device is powered by non-rechargeable batteries and you were unable to turn it on, consider replacing the batteries. To be 100% sure that the batteries need to be replaced, test them on another device which uses batteries of the same type.

Maybe your device's bluetooth issue can be resolved easily by the manufacturer's customer support team. All you need to do is to call them and follow their instructions. Also, most of the manufacturers have a troubleshooting page on their websites, which can help you fix your device's bluetooth feature by yourself.

Bluetooth devices cannot communicate unless they are paired. In order to pair devices, you need to enable the Bluetooth feature on both of them. Then, go to the bluetooth menu of one of the devices and through it select the other device and tap on the "Pair" button. Then, follow the instructions you will be given.

Go to the Bluetooth menu of the computer or another mobile device and scroll down to see the list of paired devices. Locate the device you have issues with (e.g. bluetooth speaker, headphones, etc.) in establishing Bluetooth communication and remove it from that list, by tapping on it and selecting the remove (delete) button. Then, initiate the pairing process again and follow the instructions.

If this method didn't work, check out the other solutions.

In order for a Bluetooth communication to be established, the Bluetooth feature should be enabled on both the devices. If it is enabled on both devices, but a communication isn't established and if you verified that your device's Bluetooth feature works, check if the other device's Bluetooth feature works, too. For example, try pairing the device to another device.

Note: If you determined that the other device's bluetooth doesn't work, restarting the device should make it work again.

Maybe your Bluetooth devices are not compatible. For example a device which has the Bluetooth 2 version won't be able to recognize a Bluetooth device which has the Bluetooth Smart version (commony found in gadgets such as heart-rate monitor, fitness bands, etc.).

Usually, Bluetooth devices are backward compatible, so, you shouldn't have a problem to pair a Bluetooth v2 device with Bluetooth v4 device.

Note: Consult the device's manual to check how compatible your device is with other devices.

If your Wi-Fi router is near the Bluetooth device(s) and you have issues with establishing a good Wi-Fi connection between them, move the devices away from the router. Wi-Fi routers might interfere with the Bluetooth signal as they work on the same frequency.

Make sure to be as far as possible from Wi-Fi routers if you want a strong Bluetooth connection.
