Bluetooth disconnects itself? See how to solve and possible causes | computers

If your Bluetooth is not working or disconnects by itself, some tips can help you solve the problem. Bluetooth is the basic connection of many devices. Through the connection, it is possible to avoid the use of wires in items such as mice, keyboards and speakers, which helps to keep the space more organized and less polluted, in addition to giving the user more freedom. However, this connection can suddenly end.

The Bluetooth network is limited. The distance between the user and the signal source can interfere with the connection of devices such as headphones and headsets. Equipment power consumption can also cause disconnection due to computer or cell phone power saving settings. Having that on mind, TechTudo prepared this guide with possible causes and solutions for Bluetooth errors.

A broken or broken Bluetooth connection on your computer or other devices can be the result of many different factors. Some are simpler and can be identified with a simple conference, others are more complex and can be directly connected to the Bluetooth version. Discover some of those reasons below.

1. The device is out of range of the computer

Bluetooth is a short-range network. The maximum network power used by most Bluetooth devices is 2.5 mW (milliwatts), which corresponds to a distance of up to 10 meters. Once this distance is exceeded, the signal loses strength and the device can be disconnected.

In most wireless devices, it is possible to recognize the moment when distance starts to interfere with the connection. Bluetooth headphones, for example, can start to malfunction during audio playback when the user moves away from the signal source.

The main advantage of many Bluetooth devices is the fact that they work on batteries or batteries, which allows them to work even far from a source of electricity. However, the battery charge is not permanent and at some point the device will be discharged.

It is important to always check the charge level of the device. Again, using headphones as an example, most models emit an audible warning to indicate that the battery is low and can turn off at any time.

3. Signal interference

Interference is a common cause of Bluetooth problems. That’s because the frequency used by this network — 2.45 GHz — is extremely common among many wireless devices. Devices such as Wi-Fi routers, surveillance equipment, cell phones, microwave ovens, among other devices, use the same frequency, which can “encode” the Bluetooth signal.

The advice is to always check the specifications of the devices present at home. Wireless equipment is always accompanied by an instruction manual or a tag indicating the frequency the device uses.

4. Network incompatibility

Although Bluetooth hasn’t changed much over the years, some devices come with improved versions of the network, such as Bluetooth Low Power, known as BLE (Bluetooth Low Energy), or simply Bluetooth Smart. .

This network differs from the “classic” technology and can be considered as its improved version. Because of this, the Bluetooth device may be considered incompatible and will not appear in the device manager.

Bluetooth disconnection on its own is a common but easy problem to fix. Some solutions are simpler, such as restarting the device and waiting for the connection to return to normal, others are more complex and require more patience from the user. Learn more about the solutions below.

1. Check the battery of the Bluetooth device

As mentioned earlier, a low battery level can prevent the device from working properly or even disconnect it. To work around this problem, just check the battery charge level. If the battery is weak, put it on charge and wait.

2. Change the power settings

By default, devices have special settings to reduce power consumption. Windows, for example, can disable Wi-Fi or Bluetooth settings when the computer is idle. On cell phones, power saving mode can be configured to disable connections to preserve the device’s battery.

To resolve this issue, go to Settings > System > Power & sleep > Additional power settings and turn off the device’s power saving options. If this option is not active, look for settings that limit device processing or disable connections.

3. Restart the Bluetooth device

Restarting the connection is one of the easiest ways to fix the problem. In the case of Bluetooth, turning the network off and on again after a few minutes can fix errors such as Bluetooth not finding a device to pair with, Bluetooth device not connecting, or device disconnecting itself.

4. Remove the Bluetooth device and pair it again

By the same logic as the previous topic, re-pairing is also an effective action to correct communication problems. Wireless devices that are already connected to a computer or mobile phone may experience problems when used after a long period of connection. In this scenario, turning off the device and re-pairing can refresh the network and enable normal communication.

To remove a Bluetooth device from Windows, go to Settings, then “Bluetooth devices”. Find the desired device in the list and click “Remove device”. Then just reconnect it to your computer and pair again.

5. Run the troubleshooter

Troubleshooting is an option present in many software and aims to correct errors present in the system. Typically, this option may appear when a problem is identified — such as a Bluetooth device failure.

To find the Windows 10 troubleshooter, go to Settings > Update & security > Troubleshoot > Advanced troubleshooting > Bluetooth > Run the troubleshooter. Select this option and wait while the device is scanned for the cause of the error. If the system finds the root of the problem, a correction is made to get the software working properly again.

6. Update or reinstall the Bluetooth drivers

Bluetooth drivers are software that enable communication between Bluetooth devices. Updating these programs is essential for proper connection.
