Bluetooth does not see the device? How to solve a connection problem. What to do if your smartphone does not find a Bluetooth headset

IN in this case The brand of the headset or phone is not important. Standard bluetooth connection 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 to additional settings. IN selected models phones they are called “Device Visibility Time”, and somewhere “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.

Sometimes, after purchase or rental Bluetooth micro earphone, customers call our online store and say that the earphone has stopped working. But for the most part, the wording that applies is: “I can’t connect . If the same situation happened to you, there is no need to panic. There are a number of nuances that you need to know and take into account when using a Bluetooth micro-earphone. Factors that may cause you to feel that the device is not working include: earwax clogging the speaker output, incorrect connection Bluetooth earphone headset, incorrect placement of the earphone capsule in the ear, incorrect placement of the headset on the body, incorrect phone settings or incorrect placement of the battery. Let's look at each situation separately and understand what to do in this or that case.

The Bluetooth earpiece speaker output is clogged with earwax

There are situations when a person has connected and put on the headset correctly, but still nothing can be heard in the Bluetooth headset. Most likely, the problem is not in the Bluetooth headset of the micro-earphone. Most likely, due to poor hygiene, the speaker output became clogged with earwax. Today there are already developments (for example, the Microtone company) that do not allow earwax to clog bluetooth speaker micro-earphone: for 11 mm earphones, the “open sound labyrinth” technology, for 6 and 9 mm earphones, the “closed sound labyrinth” technology (more about the types of micro earphones). If you have an older earphone model that uses a felt filter to keep the speaker from getting dirty, you'll need to remove it and replace it with a new one. This is done using improvised means, for example, a needle to remove the battery.

You need:

1. Using a needle, remove the dirty filter from the Bluetooth micro-earphone

2. Check availability earwax in or near dynamics

3. If dirty, carefully clean the speaker and the area around it, so as not to damage the speaker itself.

4. Place a new felt filter in place of the old one.

5. Connect the Bluetooth headset and check how it works

Incorrect battery placement

As you already know, the earphone will not work without a battery. All Microtone Bluetooth headphones use Camelion LR 521 batteries. Some older-style 6 mm headphones use 337 format batteries (SR416SW). And sometimes people face the problem of incorrect placement of this battery in the earphone. We remember from our school physics course that you must always maintain the polarity of the battery (+/-). Accordingly, if you mix up the sides, the earphone will not work ( detailed description micro headphones can be viewed). Correct placement of batteries:

For an 11mm micro-earphone “+” outwards, “-” inwards, towards the speaker

For a 9 mm micro-earphone “-” outward, + inward, to the earphone


For a 6 mm micro-earphone “-” outward, “+” inward, towards the earphone


An indication that the earphone is working is a slight noise that comes from the speaker after you insert the battery into the micro-earphone jack. Based on this, we can say that the earphone is working properly and the problem is not at all in its performance.

Incorrect placement of the Bluetooth headset on the body

In the catalog of the manufacturer's website microtone.com.ua there are 7 types of wireless Bluetooth headsets for micro-earphones. Three of them must be worn around the neck (Plantronics, Nokia, Plantronics MIC), since the loop that you put on the neck is an antenna that transmits the signal from the Bluetooth headset to the micro-earphone. There are often cases when a person connected a headset, but forgot to put it on his neck. Accordingly, in this case, he will not hear the interlocutor. The Watch headset, like a regular watch, fits on your wrist. The signal transmission range of the Watch headset is approximately 20-40 cm. And, accordingly, if you don’t raise your hand to your ear with the earphone, you won’t be able to hear anything either. Accordingly, you need to carefully familiarize yourself with the operating features of the Bluetooth headset and always place it correctly on your body.

Incorrect connection of the bluetooth headset

When pairing with the headset for the first time, you need to find it in the list of active Bluetooth devices and connect it to your phone. Since the headsets have the same name (PLT_MLXX, Nokia BH-108 or PLT_M20), you may simply confuse your device with the device you connected earlier. In this case, cancel pairing, delete all connected devices from the phone's memory and restart the search. Now you will definitely connect your headset. Some phones offer to rename the headset because a similar name has already been saved in the phone's memory.

Setting incorrect phone settings

In this case, it all depends on the phone model. For some models, for example the iPhone, the sound, by default, may be transmitted not to the Bluetooth headset, but to the phone speaker. To fix this, in the call menu you need to change the sound source to a Bluetooth headset. Below is an iPhone example of how to do this:

In a similar way, this can be done if necessary in the call menu of any other phone brand.

Incorrect placement of the bluetooth earphone capsule in the ear

It is very important to correctly place the Bluetooth earpiece in your ear. The earpiece speaker has a small diameter and narrow directivity. We recommend placing it in your ear strictly parallel to the surface of the earth. Because if you place it at the wrong angle, you can push the speaker output against the wall of the ear canal and partially or completely stop hearing your interlocutor. In order to correctly place the Bluetooth micro-earphone in your ear, you can call your assistant before the exam and, at the time of your communication, align the earphone in your ear so that the sound volume is maximum.

1. A fall from a height of more than 1m may damage it.

2. The earpiece should not be pressed or squeezed.

3. Moisture ingress

4. After use, you should not leave the battery in the earpiece, as this may cause oxidation of the contacts.

5. Do not bend the loop of the Bluetooth headset micro-earphone at an acute angle, as you can break the inductive winding of the wires.

If you follow all the above tips, you are unlikely to have any difficulties using wireless bluetooth micro earphone. For our part, we wish you only good use devices and are always ready to help you. If you cannot solve the problem on your own, please contact us.

Sometimes electronics malfunction. Sometimes it's the fault hardware, sometimes the problem is software. But most often it is a combination of a variety of factors.

If you connect the headphones to the charger and the indicator lights up, then everything is working properly. normal mode and you just have to wait fully charged battery

If you connect the headphones to the charger and the indicator does not light up within a few minutes, the headphones may be faulty and you need to contact the nearest authorized service center for electronics repair.

Make sure the outlet you are plugging into Charger, working. If you connect USB headphones cable to the computer, make sure that USB port the computer can work in charging mode, not all USB ports can transmit the required level of current to begin the charging process of the headphones. Typically laptop USB ports that are capable of charging external devices, are indicated by characteristic pictograms in the form of a lightning bolt, an image of a battery, or something similar. If nothing happens when you connect to one USB port, try connecting to another or to another computer.

The phone or computer does not see your wireless headphones because they are turned off


Wireless headphones have a so-called “standby mode”. It turns on when there is no active data transmission session to the headphones from the sound source. Those. you are not listening to music and the phone is not sending any sounds to the headphones. At this moment, the headphones are still connected to the phone or computer, but they are in “sleep mode”, power consumption is significantly reduced, but the battery is still consumed. And if you leave the headphones in this mode for several days, the battery will be completely discharged and they will stop working. Just charge the headphones and turn them on.

Pairing procedure


If you connect Bluetooth headphones to your phone or computer for the first time, you need to carry out the pairing procedure so that the phone and headphones transmit authentication codes to each other and start working in pairs. Without pairing your devices, your headphones won't work with your phone and your phone won't see your headphones in the list of available devices. You need to switch the headphones to pairing mode with the new device. Find out how to do this from the instructions below.

By following the link above you can get acquainted with detailed instructions initial pairing of devices. After this procedure, you will simply need to turn on the power to the headphones, after which they will automatic mode will connect to the phone within a few seconds.

Wireless headphones do not connect to the phone because Bluetooth is disabled on the phone


This is a very banal reason, but you will be surprised how many people do not realize that they must turn on the Bluetooth module in their phone. Check, this is usually done in the panel quick access or in the Settings menu. Just find the “Bluetooth” item there and check if it works.

Some phone models have the hide option enabled by default. Bluetooth phone from other Bluetooth devices, i.e. even if all devices are working properly and work as expected, they will not see the phone and will not be able to receive a signal from it. Try disabling this option. In the screenshot above I showed how it looks on my phone Xiaomi company- called "Visibility". As you can see, in my case it is disabled, so all surrounding devices can see my phone and connect to it with using Bluetooth. If I activate it, only previously paired devices will be able to connect to the phone, and new wireless headphones will not see the phone and will not be able to connect to it.

Wireless headphones do not work with the phone due to different hardware versions of the Bluetooth module


IN general case This shouldn’t happen, Bluetooth is a backwards compatible technology, i.e. Bluetooth 3.0, Bluetooth 4.0 and should be compatible with each other. But this is in theory, but in practice it may happen that due to errors in the software or a combination of hardware and software glitches headphones and phone may not see each other. This happens extremely rarely, but it does happen. Therefore, pay attention to what version of Bluetooth your phone and headphones have; if they are different, there may be a possibility of incompatibility between these two devices.

In this case, try connecting the headphones to another phone, preferably a different one. Bluetooth version. If the headphones work fine with another phone, then most likely you are faced with a rare problem of incompatibility between two specific gadgets. The only way to overcome the problem in this case is to replace the headphones or phone with a different model.

Once again, I want to draw your attention to the fact that this is a very rare problem and should only be considered if you have tried all other ways to connect wireless headphones and they did not work.

The distance from the sound source to the wireless headphones plays a key role for reliable signal reception


Make sure the sound source is within 10 meters of your wireless headphones. Please note that 10 meters is a reliable coverage area for Bluetooth devices without obstacles such as walls, cars and trees. If you want to install a sound source in one room and listen to music in another, be prepared for the possibility that serious interference may occur, including complete loss of signal. Bluetooth has a fairly low radio signal power and is therefore designed to operate over a very limited range. But electricity is consumed in very moderate quantities.

Headphones are broken


Wireless headphones are more expensive than their wired counterparts, so many people try to save money and buy inexpensive ones. wireless models. remember, that free cheese doesn’t happen, and if you bought very cheap Bluetooth headphones, you may become a victim of the manufacturer’s total savings on every element of the headphones, from hardware to software. The likelihood of breakdown increases significantly.

If your headphones do not work with your phone, make sure they are in working order. Try turning them on. If they don't turn on, put it on charge. If they don’t charge and don’t turn on, the verdict is obvious: they’re broken. If they charge but don't turn on, try putting them into pairing mode by holding the power button for a long time; depending on the model, you may need to hold the button for up to 10 seconds. If after this the headphones do not turn on and the phone does not see them, most likely they are broken and need to be repaired or replaced.

Another reason why wireless headphones fail is poor quality built-in battery. You bought headphones, listened to them for a couple of weeks, and then they began to hold a charge for only a few tens of minutes instead of the promised several hours. If this happens, this is a manufacturing defect and you should try to return the headphones to the manufacturer. Or, if there is such a desire, repair it under warranty.

Another type of hardware failure is constant interference during sound playback, even if the sound source is a few centimeters from the headphones. If, even at a very close distance from the source, the sound is reproduced with interference or is interrupted, this is a breakdown of the transmitting device. Bluetooth module. Depending on the situation, return the headphones to the manufacturer or have them repaired.

Water - main enemy wireless headphones. Unless the packaging or instructions clearly indicate that they are protected from moisture or splashes, try not to expose the headphones to water; even a walk in light rain can be fatal to the electronics. It is for this reason that I highly recommend not using regular headphones during heavy physical training. During training, you actively sweat, and sweat is much more aggressive than ordinary water. electronic components. If even one drop gets inside the headphones, serious problems can occur, including complete breakdown of the device. You can only play sports with headphones that are protected from sweat and moisture.

After purchasing a Bluetooth headset, many users encounter certain difficulties in pairing it with mobile phone and further configuration. Similar problem due to the fact that not all models of wireless headphones can work with music files. Therefore, let’s look at how to set up a Bluetooth headset on Android so that you can use it not only to make calls, but also to listen to audio.

Initial setup of the Bluetooth module

Before you start using hands-free, when you connect it to your smartphone for the first time, you will need to pair two devices: Android and bluetooth earphone. For this it is necessary that mobile device the possibility was provided wireless transmission information via radio channel.

The initial setup of the Bluetooth headset is as follows:

After successful pairing, the recognized headset will appear in the “Connected devices” section.

Now, in order for the sound when making calls to go not to the smartphone speaker, but to the Bluetooth earphone, in its settings you need to check the “Sound during a call” item. Checking the box next to “Multimedia Sound” will allow you to listen to all multimedia files through hands-free.

Playing music via Bluetooth headset

Some wireless headphones are not provided by the manufacturer with the ability to broadcast a multimedia stream. Such products are used only for talking during phone calls. Similar restrictions apply to program level, so they can be bypassed using special software.

One of the programs that allows you to expand functionality wireless headset, is Mono Bluetooth

. It works like this:

By activating media redirection via Mono Bluetooth, your earbud will always be active and play sounds from audio and video players, games, system applications and so on. This greatly drains the power supply of the headset. Therefore, if unnecessary this program It's better to turn it off.

Problems connecting a Bluetooth headset after updating Android

Many owners of smartphones and tablets, after upgrading the software, encounter malfunctions in the operation of certain modules on mobile device. If updated Android completely refuses to work with wireless earphone, it can be argued that the problem is software in nature. However, solving it can sometimes be quite difficult. This is due to the fact that the radio module does not have its own settings - they are built into the system and are closed from external interference. Therefore, you will not be able to separately update or roll back the Bluetooth module parameters.

The following steps will help restore Bluetooth functionality after upgrading Android.

Bluetooth is a wireless connection.

The purpose of the device is to connect different devices, as well as file transfer and exchange.

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 top level For security purposes, device detection is disabled. That is, in order for other opponents to see you, it must also be “activated”. Only after this the equipment is ready for use.

Problems with the device

One of the main malfunctions in the operation of the adapter is that Bluetooth does not see the device. There are many reasons for this.

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.

Sooner or later everything requires adjustment. Bluetooth is no exception, which can also fail. What to do if Bluetooth on a laptop does not see the device? Let's solve this problem.

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.

Working with utilities on a laptop

Interestingly, utilities can switch the bluetooth state. So, for example, “airplane mode” can disable it altogether. For computers different brands These are different utilities, but there are many of them.

If after reinstallation Windows systems If you don’t want to install the utilities that the setup package provides, try downloading the necessary tools 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).

BIOS settings

There are laptops in which you can configure Bluetooth functions in the BIOS system.

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.

Bluetooth drivers: installation on a laptop

A fairly common cause of adapter malfunction is that the wrong drivers are installed or there are none at all.

How to recognize this problem in Device Manager:

  • The yellow exclamation mark is next to the word Bluetooth.

  • There is “unknown equipment” in the list.
  • There are no similar sub-clauses at all.
  • "Generic Bluetooth Adapter" is where "Bluetooth" should be.

Let's say you updated the device drivers and the system reports that more update not required, but the module still doesn't work. This does not mean that the message is true. Windows simply doesn't have anything else to offer you.

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 typing in search engine the phrase “Laptop_model support.” If the required driver no, 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.

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 click in the device manager right click Misha on the word Bluetooth.

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.

If there are problems with the operation of the device on your phone. The very first thing to do is to determine the nature of the problem.

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?

The adapter does not turn on

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 oversupply temporary files or system glitch.

By doing of this action, all your photos, songs and videos will be deleted. In order to save them, rewrite this data to another medium before resetting the settings.

In order to complete full reset settings, you should follow this algorithm of actions: “Settings” / “Reset settings”.

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.

The mobile does not see the Bluetooth device, but the adapter turns on

If this situation occurs, you need to check whether Bluetooth is turned on.

Turning on Bluetooth

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.

The adapter turns on, but no data transfer occurs

In case your mobile old version operating system, then its HT module does not have a data transmission function.

To solve this problem, you need to update the OS - if you receive auto-updates on your phone. Or download bluetooth app Fle Transfer from Play Market.

It is very convenient to use bluetooth to exchange information between your phone and personal computer or to listen to music using wireless headphones.

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.

Bluetooth device and driver status

First you need to determine whether your Bluetooth is still in place after the update? Are the drivers installed and how correctly do they work?

To check whether it is installed on your computer, go to the “Control Panel”, in the “Device Manager” section.

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 the opposite would not happen exclamation point. This means that all settings are correct and everything is installed.

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.

If the drivers are still not installed, in the device manager, in the “other devices” sub-item, “ unknown device", which, most of all, 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:

What does enabled Bluetooth look like on the toolbar?

If bluetooth is fully working, is present on your computer and is even turned on, it should be displayed with a special icon on the toolbar.

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.

Then, go to the “Devices” section and select the “Bluetooth” sub-item.

If you are using a laptop, you need to find it on the keyboard special key, with which the module is turned on and off. If you don’t know where such a button is located, you may accidentally turn off Bluetooth all the time and puzzle over what’s happening with the adapter.
