In this case, the brand of the headset or phone is not important. The Bluetooth communication standard is universal and if problems arise with the visibility of devices, there can be only three reasons for the problem.
Bluetooth is not enabled on your phone/tablet
This is the first thing to check in such a situation. Go to your phone settings and make sure Bluetooth is activated and the device visibility time is set correctly.
 |
Visibility time is set in additional settings. In some phone models they are called “Device Visibility Time”, and in some cases “Detection Timeout”. It is best to check the "Do not use timeout" option. If, after changing the settings, the Bluetooth headset still does not connect, check two more options.
The headset is not turned on or is discharged
In some headsets, the power button must be held for at least five seconds to start operating mode. When the device starts working, the indicator light will start flashing. After this, you don't need to do anything. All modern Bluetooth headphones connect to the phone automatically.
If you press the button long enough and there is no response, the headset is either discharged or faulty. Please note that even a new Bluetooth headset may have an empty battery. Batteries lose charge if left unused for a long time. When charging does not help and the new headset does not turn on, you need to change it from the seller.
The headset has already been paired with another device
Sometimes a Bluetooth headset, which has already been tested many times with another gadget, does not connect to a new phone. The fact is that the headset is automatically connected to the first device, and then the pairing function is disabled. To reactivate it, you need to hold the power button until the indicator lights up. A window will appear on your phone to enter the pairing code. The factory code adopted by manufacturing companies is 0000, four zeros.
These are the main reasons why the phone does not see the Bluetooth headset. Due to the fact that such accessories do not have complex settings, there are no other reasons for malfunctions.
This article will tell you about the reasons why an Android phone or tablet does not connect to Windows 7/10 via Bluetooth, and will also tell you what to do in such a situation.
This article is suitable for phones and tablets of all Android device manufacturers: Samsung, LG, Sony, Huawei, Xiaomi, HTC, ZTE, Fly, Alcatel and others. We are not responsible for your actions.
If Android does not connect to a laptop or computer via Bluetooth, then the reasons for this problem may be hidden both in the module on the PC and in the operation of the gadget itself. Often you can fix the error yourself, but in the most difficult situations of hardware damage you need to visit a service center.
First you need to determine which device is problematic. It is possible that the Bluetooth module is simply turned off on Android. To turn it on, just go to settings and move the corresponding switch to the “ON” position.
Increase
Bluetooth should also be turned on on the computer. On Windows 7, the module is enabled in the “Devices and Printers” section, and on Windows 10 there is a separate tab in “Settings”. The user also needs to allow other devices to detect the computer, otherwise the radio signal simply will not be detected.
It is important to check whether the necessary drivers are installed on your computer for Bluetooth to work. The module will not work without them, and a wireless connection will not be established.
Increase
If the telephone module shows an eternal loading or does not turn on, then the cause of this may be a hardware or system problem. You should try rebooting the gadget, resetting network settings or doing a hard reset. During a hard reset (complete Android reset), all user information will be deleted from the phone, so do not forget to first create a backup copy of your data.
When problems with connecting via Bluetooth and transferring files began to be recorded after installing custom firmware, you need to abandon it. Use only official firmware from the tablet/smartphone manufacturer or use stable builds where all functions work correctly.
When there are no problems on the software side, you need to contact the service center. There is a possibility that the Bluetooth module has failed due to water ingress, mechanical impact or the influence of other negative factors.
Correct connection of Android via Bluetooth to a computer
Often, problems during connection are not due to hardware or system failures, but due to incorrect user actions. You can avoid errors by following the instructions when establishing a connection with a PC via Bluetooth:
- Open “Settings” in Windows 10 and go to the “Devices” section.
- Go to the “Bluetooth” tab.
- Move the slider to the “ON” position.
- In the “Related Settings” section, click “Advanced Settings”.
- On the “Settings” tab, check all the boxes so that you can identify the computer on another device.
Increase
In Windows 7, Bluetooth settings can be opened by right-clicking on the icon in the system tray. In the settings, you must also allow the computer to be detected by other devices.
Increase
The following steps are to enable detection on Android:
- Go to settings, open the “Bluetooth” section.
- We turn on the module by moving the slider to the “ON” mode.
- Below you can see the phone name. Click on it to change the mode to this: “Display for nearby devices.”
Increase
After launching the module and allowing it to be displayed on other devices, the name of the gadget will be displayed in the Windows settings. You need to click on it, and then click “Pair” to establish pairing. A secret code will be shown on your computer and phone screen. The user needs to confirm that it matches, and then pairing will be established.
Increase
Once the connection is established, you can transfer data in both directions via Bluetooth. This method is not the fastest; it is much more efficient to use a USB or Wi-Fi cable for connection, but Bluetooth is quite suitable for solving certain problems.
Unstable connection
It happens that Bluetooth does not maintain a connection on Android, that is, frequent disconnections occur during operation. It is important to note that the problem may occur due to a problem in one of the two devices. In this case, we will look at how to solve the problem on an Android tablet or smartphone.
This problem cannot be solved using standard methods, since the system does not have suitable Bluetooth module settings. Therefore, you can use third-party utilities.
You can use the Bluetooth Fix Repair app to do this. The principle of its operation is to correct any deviations in the system settings of the wireless module. The utility contains parameters that are responsible for the correct operation of Bluetooth.
During startup, it begins to scan the parameters of the tablet or smartphone. If any errors are detected in the system files, they are corrected to the correct ones, and the Bluetooth module begins to function as expected. To use the utility you need root rights.
Bluetooth Fix Repair is easy to use and free. It can be downloaded from Google Play
After reinstalling Windows 10, 8 or Windows 7, or simply deciding one day to use this function to transfer files, connect a wireless mouse, keyboard or speakers, the user may find that Bluetooth does not work on the laptop.
This material provides more details on what to do if the function does not work at all and Bluetooth does not turn on, errors occur in the device manager or when trying to install a driver, or does not function as expected.
Finding out why Bluetooth doesn't work
Before you begin taking direct action to correct the problem, I recommend following these simple steps that will help you navigate the situation, suggest why Bluetooth is not working on your laptop, and perhaps save time in further actions.
If, after going through the list, you stopped at item 7, you can assume that the necessary drivers for your laptop’s Bluetooth adapter are installed, and the device is probably working, but is disabled.
It is worth noting here: the status “The device is working normally” and its “enabled” status in the device manager does not mean that it is not disabled, since the Bluetooth module can be disabled by other means of the system and laptop.
Bluetooth module (module) disabled
The first possible reason for the situation is a disabled Bluetooth module, especially if you often use Bluetooth; just recently everything was working and suddenly, without reinstalling drivers or Windows, it stopped working.
Function keys
The reason that Bluetooth does not work may be turning it off using the function key (the keys in the top row can operate while holding the Fn key, and sometimes without it) on the laptop. However, this can happen as a result of accidental keystrokes (or when a child or cat takes possession of the laptop).
If in the top row of the laptop keyboard there is a key with an image of an airplane (airplane mode) or the Bluetooth logo, try pressing it, as well as Fn + this key, this may already turn on the Bluetooth module.
If the airplane mode and Bluetooth keys are missing, check if the same thing works, but with a key with a Wi-Fi icon (this is present on almost any laptop). Also, on some laptops there may be a hardware switch for wireless networks that also disables Bluetooth.
Note: if these keys do not in any way affect the Bluetooth state or turn Wi-Fi on and off, this may indicate that the necessary drivers are not installed for the function keys (however, the brightness and volume can be adjusted without drivers).
Bluetooth disabled on Windows
In Windows 10, 8, and Windows 7, Bluetooth can be disabled through settings and third-party software, which may look like "not working" to a novice user.
Laptop manufacturer's utilities for turning Bluetooth on and off
Another option available for all versions of Windows is to enable airplane mode or disable Bluetooth using programs from the laptop manufacturer. These are different utilities for different brands and models of laptops, but all of them can, among other things, switch the state of the Bluetooth module:
If you do not have the manufacturer’s built-in utilities for your laptop (for example, you reinstalled Windows) and decided not to install proprietary software, I recommend trying to install it (by going to the official support page for your particular laptop model) - it happens that you can only switch the state of the Bluetooth module in them (with original drivers, of course).
Enabling and disabling Bluetooth in the BIOS (UEFI) of a laptop
Some laptops have an option to enable or disable the Bluetooth module in the BIOS. Among these are some Lenovo, Dell, HP and more.
You can usually find an item to enable or disable Bluetooth, if available, on the “Advanced” or System Configuration tab in the BIOS in the items “Onboard Device Configuration”, “Wireless”, “Built-in Device Options” with the value Enabled = “Enabled”.
If there are no items with the words “Bluetooth”, look for the presence of the WLAN, Wireless items and, if they are “Disabled”, try also switching to “Enabled”; it happens that the only item is responsible for enabling and disabling all wireless interfaces of the laptop.
Installing Bluetooth drivers on a laptop
One of the most common reasons why Bluetooth does not work or does not turn on is the lack of necessary drivers or inappropriate drivers. The main signs of this:
Note: if you have already tried to update the Bluetooth driver using the device manager (the “Update driver” item), then you should understand that the system message that the driver does not need updating does not mean that this is really the case, but only reports that Windows cannot offer you another driver.
Our task is to install the necessary Bluetooth driver on the laptop and check if this solves the problem:
Often, on official websites for one laptop model there may be several different Bluetooth drivers or none at all. How to be in this case:
In the list at the bottom of the devid.info search results page you will see which drivers are suitable for this device (you do not need to download them from there - download them from the official website).
When there is no driver: this usually means that there is a single set of drivers for Wi-Fi and Bluetooth for installation, usually located under a name containing the word “Wireless”.
With a high probability, if the problem was in the drivers, Bluetooth will work after their successful installation.
Additional Information
It happens that no manipulation helps to turn on Bluetooth and it still does not work; in such a scenario, the following points may be useful:
Perhaps this is all I can offer on the topic of restoring Bluetooth functionality on a laptop. If none of the above helped, I don’t even know if I can add something, but in any case, write comments, just try to describe the problem in as much detail as possible, indicating the exact laptop model and your operating system.
Bluetooth wireless technology has occupied its niche for a long time and has been popular all over the world for many years now. Moreover, every modern smartphone, tablet, laptop, etc., is equipped with such a module, the “Bluetooth Settings” section will help you with setting it up. But, a very common error occurs when Bluetooth does not find a device to connect.
What is this error and why does it appear? To answer this question, you must first understand how the technology works and how to properly search for available connections. It is worth noting that such errors, as a rule, occur on laptops, since operating systems have very flexible configuration of radio modules, which is why users often simply make certain mistakes.
How the technology works
In fact, this is the most common radio communication that operates at a frequency of 2.4 GHz. Each adapter works both for receiving and emitting radio signals. However, for increased security, device detection is disabled. In other words, even if you turned on the Bluetooth adapter, for example, on your smartphone, the computer will not be able to find it. See how to find and enable Bluetooth on Android devices.
After turning on the adapter, you still need to activate “Discovery” of the device. Only in this case will you be able to find the necessary equipment and connect to it. This is done to save electricity. After all, when the adapter is turned on and the detection function is active, the Bluetooth radio module consumes more energy.
In addition, if we are talking about a computer, then the reason why Bluetooth does not find the device is that the drivers are not working properly. We described how to connect Bluetooth on a computer in a previous article. The fact is that for the radio module to work correctly, special software is required. It is the appropriate software that allows you to control the operation of such equipment. Typically, drivers are available on the disk that comes with the laptop upon purchase. However, if there is no such disk, then the necessary programs can be downloaded from the official website of the laptop manufacturer.
Why Bluetooth doesn't find devices: Video
Why doesn't Bluetooth find devices?
There are many reasons why Bluetooth does not find devices. The most common errors include the following:
- Discovery is disabled on the device you are looking for.
- The connected device is out of range of the adapter.
- The software is not working correctly.
- Strong interference.
First of all, when connecting any equipment via a Bluetooth wireless network, you should check whether detection is enabled.
As mentioned above, even if Bluetooth is turned on, you can only find it by turning on discovery. If this does not help and the Bluetooth equipment is still not found, then it is quite possible that the device is out of range of the radio module.
The fact is that the adapter has certain limitations. Of course, the range of action with line of sight can range from 10 to 50 meters, depending on the model. But it is worth remembering that under normal conditions, in apartments and houses, these figures are significantly lower. In addition, do not forget about the interference that can be created by household appliances, such as cordless phones, microwave ovens, and so on.
Problems with finding available Bluetooth connections are often caused by incorrect drivers. In this case, it is recommended to visit the official website of the laptop manufacturer and download the latest version of the software. If the software is installed correctly and everything works, then your radio module will be displayed in the Windows Device Manager. Moreover, you will be able to see its exact name.
What is bluetooth and how does it work?
Bluetooth is a wireless connection.
The purpose of the device is to connect different devices, as well as transfer and exchange files.
The adapter functions as a regular radio receiver, which is configured to send a signal and to receive it. Simply enabling the function will not be enough to work.
For the highest level of security, device detection is turned off. That is, in order for other opponents to see you, it must also be “activated”. Only after this the equipment is ready for use.
The most common:
- The software is not working properly.
- The device they are trying to find does not have discovery enabled.
- Big interference.
- The connected device is outside the adapter's range of influence.
Therefore, before you begin to fix the problem, you need to figure out why the device does not see the device.
The adapter on a laptop may malfunction over time or immediately, during the first attempt to connect it. Find out the cause of the problems and begin to fix them.
We will look at options for changing configurations using utilities and how to configure the device in the BIOS.
If, after reinstalling the Windows system, you do not want to install the utilities that the setup package provides, try downloading the necessary things from the official support page for your laptop.
There are options when you can replace the Bluetooth module configuration only with the help of utilities.
It happens that you can switch the adapter state only with their help (if you have original drivers).
These include HP, Lenovo and others. As a standard, in the “Advanced” tab there is an item where you can turn the function off and on.
Sometimes - in the System Configuration tab, in the sub-items “Onboard Device Configuration”, “Wireless”, “Built-in Device Options”. The Enabled value in them should be “enabled”.
If there are no bookmarks with the word Bluetooth in the BIOS, you need to try setting the WLAN and Wireless items to the Enabled state.
Sometimes one tab is responsible for the active and inactive state of all wireless devices.
How to recognize this problem in Device Manager:
- The yellow exclamation mark is next to the word Bluetooth.
How to recognize bluetooth
- There is “unknown equipment” in the list.
- There are no similar sub-clauses at all.
- "Generic Bluetooth Adapter" is where "Bluetooth" should be.
To solve this problem, you need to install the driver and see if it helps. Download it from the website that represents your laptop model.
You can find the site by entering the phrase “Laptop_model support” into the search engine. If the driver you need is not available, use the most similar one.
In the case when something is already installed on your computer. You need to disconnect from the Internet and delete it.
How to remove a driver
Now you need to start installing the new software.
Often the representative's website offers not one, but several drivers for one version of the adapter.
To avoid making a mistake and select the correct one, you need to right-click on the word Bluetooth in the device manager.
Then, go down to the “Properties” / “Details” sub-item and find the “Equipment ID”. You will need the last line from the “Values” field.
Copy it and paste it into the search engine on devid.info. The system will sort the drivers that are most suitable.
It is necessary to understand whether it is activated or not, does the problem occur when the device is turned on, or does it not work at all?
If the device as a whole does not activate in any way and shows constant loading, the cause of this incident is a hardware malfunction, a problem in the system, a virus on the phone, or a program installed with which there was a conflict.
To fix the problem, try rebooting your phone.
This action would be appropriate if the problem was lack of space due to an excess of temporary files or a system glitch.
In order to perform a complete reset of settings, you should follow the following algorithm of actions: “Settings” / “Reset settings”.
Resetting your phone
If even after performing this option the problem does not disappear, then the device is simply broken. The situation can only be resolved with the help of a service organization for equipment repair.
If it does not turn on in a newly purchased phone, replace it under warranty.
If yes, then you need to enable device visibility mode and disable the Discovery Timeout options. Now the device will work in the correct mode.
Device discovery mode
To solve this problem, you need to update the OS - if you receive auto-updates on your phone. Or download the Bluetooth Fle Transfer application from the Play Market.
Bluetooth Fle Transfer
But there are unpleasant situations when, after Bluetooth updates, Windows 10 does not see the device. What to do in this case? Let's take a closer look at the situation.
To check whether it is installed on your computer, go to the “Control Panel”, in the “Device Manager” section.
device Manager
One of the sub-items there should be “Bluetooth”. If it is present, you need to check whether the drivers are installed for it? To do this, click on the name with the mouse and open the contents of the folder.
There must be an attachment in it. The main thing is that there is no exclamation mark opposite. This means that all settings are correct and everything is installed.
Drivers
There are times when a failure occurs and the required module is turned off. In this case, a black arrow appears when the name is fiddled with.
To change the settings to “on”, you need to right-click on the name and activate the device.
Unknown devices
If, however, the drivers are not installed, in the device manager, in the “other devices” sub-item, an “unknown device” will be placed, which, most likely, is your adapter.
To solve this problem, you need to update the drivers and specify the path to them.
There is another option when in the device manager you will not see anything related to Bluetooth and unknown devices.
You need to double-check and make sure that the adapter is even present on the PC. If not, you should purchase it from a specialized store and install it. The simplest adapter looks like this:
Location: in the lower right corner, near the clock.
If it is missing, do not worry - it may simply be turned off. Auto-shutdown is most likely typical for laptops, since such programs consume an excessive amount of energy.
To activate it, you need to go to the menu on the toolbar and select the “Options” sub-item.
Options
Then, go to the “Devices” section and select the “Bluetooth” sub-item.
Bluetooth connection
This happens because the phone is looking for the settings that were on the old phone. You need to configure the connection correctly and the issue will be resolved.
First, you need to set a code that will prompt the mobile device upon first connection. Then, in the window that appears, simply enter it. The connection has been established.
This was done specifically by the developers so that pairing would not occur if pressed accidentally. When the headset is connected, the indicator on the headphones will flash.
If the Bluetooth battery is low, the connection will not occur. Therefore, before using your headphones, charge them.
Very often due to the fact that they simply forgot to turn on Bluetooth and the devices do not connect.
Always first check that the headset is connected and that the time is set correctly so that another device can detect the phone.
1You need to hold down the start button on the screen and hold it until it is activated (highlighted).
2Enable bluetooth in your phone settings.
3In the list that appears, select the name that matches your headset manufacturer.
Select the desired device from the list
4Turn on the headset on your phone.
Sometimes problems arise in the operation of the device. Most often due to the user’s inattentiveness or lack of familiarity with the instructions.
To troubleshoot, you should carefully check your settings again. If this does not help, most likely a breakdown has occurred and you should contact a service organization.
Bluetooth does not see the device? How to solve a connection problem
- Easy to use
- No battery power requirements;
- Low probability of pairing with other wireless networks;
- The presence of drivers is enough to work.
- Average data transfer speed;
- When constantly turned on, it consumes a lot of energy;
- Weakness of defense.
