It has been more than 20 years since Bluetooth has been able to cooperate with devices.

However, Bluetooth connection between the devices may still be out of the way, or when trying to connect, various problems may occur.

This time, we will introduce the troubleshooting of the problem that occurs when Bluetooth is connected to a device that can be connected.

Examine the range

If there is a problem to connect the two Bluetooth devices, first check if the device is within the connection.

Usually, about 9 meters or less.Bluetooth signals pass hard objects such as walls and ceilings, but if such obstacles are available, the range of signals will be narrow.

Bluetooth sends and receive data by radio waves emitted by the antenna of each device.

Bluetooth power is weak in order to reduce the amount of battery usage in order not to hinder the transmission and reception of other devices using the same wireless frequency.In other words, Bluetooth signals are not as far as the radio waves of high -powered WiFi signals and commercial radio stations.

Restart both devices

The advice of "turn off the power and then turn it on again" is too commonplace in the digital industry, but it is effective to re -connect Bluetooth.

Paired mode according to the manufacturer explaining the device (personal computer, tablet, smartphone, etc.) Bluetooth function (such as a PC, tablet, smartphone, etc.) and then turned on again.I'll do it.

This may revive the device Bluetooth connection.

If this doesn't work, turn off both devices you send and receive, restart the device of the sender, start up completely, start the receiving device and pair.increase.

Check if Bluetooth is on

You may think that it is as stupid advice as "Please turn on the power again", but when the device is in low power mode, such as when the smartphone battery is likely to run out, the Bluetooth function is invalidated.It may be.

Also, keep in mind that Bluetooth will be invalid when you are in an in -flight mode.

Speaking of the fact that the battery is about to run out, make sure that the device of the receiving person has been charged enough that the antenna can be functioned full.

Check pairing

Many Bluetooth devices such as speakers are automatically connected when the last connected device is within the radio waves.

This is a useful feature, but if you want to play music from a tablet to a Bluetooth speaker, but if the speaker is trying to connect to your smartphone automatically, it's a little irritated.

To solve such a problem, turn off the Bluetooth function of the device you don't want to connect, and then paired it with the device you want to connect.

Alternatively, enable the Bluetooth pairing mode of the received device (such as pressing the Bluetooth button or the power button in the case of a speaker), and then connected it again.

There are also Bluetooth devices that must enter pairing code and receive pairing requests.

For example, many Bluetooth keyboards have to enter a specific code to connect to a computer or tablet.

If the pairing of the two devices is too long, check the device screen for pairing approval or code input.

Confirmation of the obstruction

There are many devices that use the low frequency range, the same as Bluetooth sending and receiving signals.

Baby monitors, cordless phones, microwave ovens, lighting equipment, etc. are the same as Bluetooth 2.Signals may be sent and received at 4GHz frequency.

If the Bluetooth connection doesn't work, try moving such a device to a place outside.

2.4GHz frequency wifi may also interfere with Bluetooth connection, so if the Bluetooth connection does not go well, turn off the wifi function of the sending device once.Or it may be a hindrance 2.Move from a lot of things that use 4GHz frequencies and pair again.

Also, if it is compatible, try to connect to a 5GHz network that can connect more devices, or 2 of the router..Try changing the 4GHz channel.

The human body may also interfere with Bluetooth signals.The main component of the human body is water, so if water is in between, transmission and reception may not work.

So, if you use a wireless headphone, etc., if the Bluetooth connection is interrupted, be careful about the device you send and receive and your body.

Delete the device

Most personal computers, tablets, and smartphones try to connect them automatically when the receiving device is active once Bluetooth is connected.

However, if the connection does not go well, it is a good idea to delete the receiving device (from the pairing list) and start over again.

To do so, go to the Bluetooth setting screen, find a device that cannot be received, and delete it from the list.

Then make the device in pairing mode again and scan the device that can be connected to Bluetooth.

Check the manufacturer's information

Bluetooth device manufacturers may update specific procedures to correct Bluetooth connection issues on websites.

Or, if there is a problem with the compatibility between the devices, the information may be posted, so if you have any problems such as trying to connect to Bluetooth, check the manufacturer's website.。

In addition, some devices such as BOSE's portable speakers and car stereo have to update software regularly, so it is better to check if your device is such a type.Yes.

Bluetooth antenna drivers may become old, especially when you have installed a new OS on a personal computer (especially Windows PC).

For such a computer, check if you need a driver update.

If your computer is a Mac and you can't connect well after trying some of the above -mentioned methods, you may have to reset your PC Bluetooth module.

To reset, click the Bluetooth icon on the menu bar while pressing the option + shift key together (if the Bluetooth icon is not on the menu bar, display Bluetooth on the menu bar in "Bluetooth" in the system environment settings.Check with the box).

Click the Bluetooth icon to display the "Debug" option.

Mouse over and click "Reset Bluetooth module".After reset, restart Mac and connect to the device again.

You can not only check if the Bluetooth driver is the latest, but also run Bluetooth troubleshooting tools on your computer.

To run on Windows 10, select "Bluetooth" in "Start button> Settings> Update and Security> Trouble Shooting" and then "Bluetooth" for "Discovering and solving other problems".

Then the procedure for the software to solve the problem.

Try with other devices

If you try all the above measures, if the connection does not work yet, there may be a problem with the device itself.To confirm that, try to see if you can connect with other devices.

For example, if the Bluetooth speaker cannot be connected to the tablet, connect to a smartphone or computer.

If you can connect with this, you can see that there is a problem with the tablet.

If you can't connect to any device, you may have a problem with the speaker, so you should return or replace it or buy it again.
