What does a bluetooth adapter look like. Bluetooth adapters for a computer: overview, specifications, selection, connection, reviews
The need to install a bluetooth adapter for a computer arises when you need to quickly move information between different devices.
For example, between a stationary PC and .

The appearance of most adapters designed to connect to a computer or laptop (which also rarely supports bluetooth) resembles a small one.
Some are even smaller.
And to boost the signal on these devices, a small antenna can be installed that adds 2-5 dBi.
Built-in bluetooth adapters are boards that connect inside a PC (usually to a PCI slot) and sometimes also provide a wireless connection using technology.
Most adapters are installed and configured automatically upon connection. Some require manual configuration.

BlueTooth technology is based on radio communication and allows you to connect two devices to each other almost imperceptibly to the user.
The advantages of using an adapter are:
The disadvantages of the device include a relatively small, compared with wireless WiFi connection, speed.
In addition, most models transmit data over a short distance.
Although when buying an adapter with an amplifier, you can increase the distance to several tens of meters - the result is impressive even for.
Device classification
Bluetooth adapters are primarily classified according to their range of action:
- old models, class 4, are able to connect two devices, the distance between which does not exceed 2–5 meters;
- devices of the 3rd class provide connections at a distance of 5 to 10 m;
Rice. 3. Standard Class 2 Bluetooth modules with a distance of up to 10m.
- The 2nd class of adapters allows you to connect if the distance between the computer and another gadget does not exceed 50 m;
- the first class, which is equipped with printers, modems and base stations, makes it possible to transmit data within a radius of 100 m from the adapter.
Using antennas that amplify the signal increases the distance. At the same time, devices of the same class provide a connection in different ways in different conditions.
Since both the range and the stability of the connection depend not only on the characteristics of the adapter, but also on the configuration of the premises, and on the material of the enclosing structures.
Bluetooth adapter features
You can use Bluetooth USB adapters in the following situations:
- to transfer information from a mobile device to a computer or vice versa. This is especially useful if there are no devices to connect and if it is impossible to use Wi-Fi for this (a technology that is not supported on older phones);
- for wireless connection of two computers within the range of the bluetooth adapter;
- to connect to a computer, digital camera, and other devices.
In most cases, using Bluetooth technology instead of Wi-Fi or cable increases the distance that connected devices can be.
For example, you can connect two computers in this way, even if they are in neighboring rooms and even apartments.
And if you need to transfer data from mobile phone old model(with a special cord format for connecting, like models or Sony Ericsson) this may be the only option available.
The only alternative is to buy a special cord, the cost is higher than that of an adapter.

Features of choosing an adapter
Before choosing a bluetooth adapter for a computer, you should make sure that it is not included in the device package.
Technology support in desktop computers wireless communication usually not provided. And to check availability, you can:
- check for the presence of the corresponding character on the keyboard;
Keys that allow you to turn on the bluetooth module on a laptop
- Open Device Manager and check for the presence of the module. The same option is also suitable for a stationary personal computer, although usually their owners already know about the installed boards and adapters.
After confirming the need to purchase a device, they proceed to its choice, focusing on three main parameters.
The first is the protocol supported by the adapter. The second is the range of the device.
And, finally, the third - the price, due to the class, and the manufacturer, and protection from external influences.
Device protocol selection
The presence of several generations of bluetooth adapters on sale complicates the choice of a suitable model.
Moreover, according to the information on the pages of online stores, it is difficult to figure out which device can be considered new and which is already outdated.
One of the outdated adapter models that can still be found on sale
It is worth noting that the data transfer rate, connection stability, and price depend on the adapter protocol.
The latest versions, 4.1 and higher, not only allow you to connect any device without connection problems, but also provide stable data transfer without interruptions and failures, and even consume less power.
In addition, when you leave the range of the adapter and return to it, the connection is restored automatically.
And modern devices can support the connection of several gadgets at the same time.
Range selection
When choosing an adapter, one of the main factors is its range.
Given that the increase in range is proportional to the increase in the price of the device, it is not necessary to buy a first-class model, the cost of which is noticeably higher. Especially when it comes to use at home, where the distance between devices rarely exceeds 10 meters.
For a home and a small office, class 2 or 3 adapters are suitable, as a rule, they do not have an antenna, and are in the price range up to 200-300 rubles.
For large rooms, it is advisable to choose class 1 models that support 4.0 and 4.1 protocols - in addition to a range of more than 50 meters, they will also provide a speed of at least 3 Mbps.
Their cost can reach 1000 rubles.
Modifications of adapters with built-in antennas are even more expensive. Most often, they provide two types of wireless communication at the same time - both Bluetooth and Wi-Fi.
Their cost can exceed 2000 rubles, but the functionality is much higher.
With the help of such equipment, information will be guaranteed to be transferred to any device - to a laptop, to a smartphone, and to another computer with a built-in adapter and supporting wireless technology.

Other Features of Choice
In addition to the range and protocol of the BlueTooth adapter, when choosing, pay attention to such characteristics as:
- type of connection to the computer;
- equipment manufacturer;
- functionality;
- strength;
- price.
The price range is important for those users for whom the speed of information transfer and range does not matter.
To connect devices located in the same room, any device is enough, even with protocol 1.2 or 2.0.
With the constant transfer of large files and a distance exceeding 10–15 meters, it is advisable not to save money, but to purchase an adapter that supports Bluetooth 4.0 or 4.1 transmission technology.
Durability matters if the device is constantly being carried and placed on different computers or laptops.
For the same situations, you need to purchase a gadget that connects to a USB port.
If the instrument is intended to be used on only one computer, an in-board model can be selected. Moreover, such adapters can also provide.
Popular manufacturers of bluetooth adapters are 3Com, 4World, Tracer, Broadcom, Atheros and GSM-Support. And among the brands, the range of which is presented budget models, it is worth noting the brands Trust and StLab.
The compatibility of adapters may also depend on the manufacturer - for example, devices from 3Com are equipped with their own drivers, which are not always detected automatically. Although most models from other companies do not even require tuning.
If you need to provide both types of wireless connection, you should pay attention to the Intel 7265NGW.AC, Intel 7260HMW.AN and ASUS PCE-AC55BT models, which support data transfer at speeds up to 867 Mbps for Wi-Fi and up to 3 Mbps for Bluetooth. Devices connect to M2 and PCI-E ports.
conclusions
The use of bluetooth adapters allows you to practically do without a wired connection of devices to each other to transfer information.
This not only increases the convenience of file sharing, but also eliminates the need to purchase data cables with different connectors for each individual gadget.
At the same time, the purchase of an adapter does not require either large expenses or significant time spent on setting them up.
Automatic device detection does not require any user action at all. And even when manual update it will hardly take more than 10 minutes.

The number of different digital devices grows every day. Many of them can and should interact with each other. Some do not do this so often, while others require an almost constant connection to exchange information, files, commands. The most common and fastest protocol for a convenient, and most importantly, wireless connection is the Bluetooth protocol.
If your device does not have a built-in Bluetooth module, you can use alternative connection options
It is this protocol that today is equipped with any smartphones, tablets, laptops, almost all TVs, multimedia centers, acoustics, and even some types of kitchen appliances. That is why you may need to install Bluetooth on your computer to work effectively and manage various gadgets or office. We will talk about how to choose a Bluetooth adapter for a computer, as well as how to install Bluetooth on a PC.
Bluetooth technology is the most common wireless data transmission system after Wi-Fi. While Wi-Fi is used more for organizing local wireless access to the Internet, bluetooth technology has established itself as the most effective method to exchange information over short distances.
The range of receivers and transmitters using this protocol is gradually increasing, but today it does not exceed 60 meters. The technology can be used to transfer files, receive and transmit sound signal, sending and receiving various kinds of commands. By connecting a computer and another device using this protocol, you can, for example, easily control internal memory smartphones, take ready-made pictures from the camera, control the TV, connect to a PC wireless acoustics or headphones and so on.
While a large number modern devices initially released with a pre-installed Bluetooth module, a PC under Windows control remain the equipment least equipped with such modules. The main reason is that most computers are assembled from different components, and most often an adapter supporting this data transfer protocol must be installed separately.
There are two types of Bluetooth adapters: internal (motherboards) and external (connected to the USB “whistles” connector, visually similar to a classic flash drive). If your computer does not have such a link to external devices, but you feel the need for it, you can purchase an external adapter separately. Even a novice user can install, connect and configure it. How to choose such a device and how to connect it to a PC, we will describe below.
When choosing a Bluetooth adapter for your computer, we recommend that you pay attention to several key parameters. One of the most important is the range of the wireless signal. Depending on how far from the PC are or can be the devices to which you want to connect, choose an adapter with the appropriate range. The maximum distance at which the adapter can establish a connection with devices directly depends on the version of the Bluetooth protocol that it supports. The higher the index of this version, the greater the range.
Also pay attention to additional features adapter and its functionality. If you need, for example, a connection with audio devices, headphones or speakers, the adapter must support the A2DP protocol. It is specially designed for audio signal transmission High Quality, but not supported by all adapters.
Features of Bluetooth versions and additional features
With the gradual development and refinement of the Bluetooth protocol, the developer of this technology continues to release newer and more advanced versions. When choosing an adapter, you should definitely pay attention to the version of the protocol it supports. The higher this value, the more functionality, range and energy efficiency the adapter has.
The maximum version to date has an index of 4.1 and allows you to establish a stable connection with devices located within a radius of 60 meters. This version has the most economical system of energy use, which is very important when connected to mobile devices running on battery power. Important advantages of the newest versions of Bluetooth are the gradually increasing data transfer rate and automatic recovery lost connection.
If you purchased an adapter that supports the most current version protocol and on a PC running Windows, an appropriate program is installed to communicate with specific device, the functionality of Bluetooth is noticeably increased, and it can be used for a variety of purposes. The program for connecting with a smartphone or tablet allows you to wirelessly connect Windows and iOS or Android to transfer photos and access the Internet. A program compatible with your audio system will allow you to turn on music, control its playback and volume.
If your apartment is equipped with a smart home system, there is special program, which will allow you to adjust the brightness of the lighting or remotely turn on various Appliances. The functionality you get with this data transfer technology is only limited by the number of devices in your home or office that support Bluetooth connectivity.
How to choose the right adapter
Based on all the information above, there are a few things you can do to help you make the right choice and purchase the Bluetooth adapter that best suits your needs. If you need to equip a stationary PC with support for this protocol, both the internal board and the external USB adapter.
Please note that the internal version may be more powerful and able to serve a wider radius than the external "whistle". Check this point before buying. As for the rest of the parameters, there is not much difference between internal and external solutions. Their design will not affect the Bluetooth configuration process in Windows in any way, nor will it affect the data transfer rate.
Connection and setup
When the adapter is selected and purchased, it remains to make the necessary windows settings and a computer in order to enable data transfer, as well as find and connect all necessary devices. As a rule, regardless of the manufacturer of this PC component, after the first connection or reboot, the Windows system automatically recognizes the type of new device, its manufacturer, downloads and installs the necessary driver on its own, which allows you to enable Bluetooth. However, this will only allow you to find your gadgets and establish a connection with them. Some of them may require you to enter a security pin code to confirm the connection. In Bluetooth 4.1, the default password is "0000" (four zeros). However, after establishing a connection, you will need a program that will allow you to work with the connected device.
The website of the manufacturers of some of these adapters may contain a proprietary program that activates the main functions of this PC component. To connect to specific gadgets (smartphones and tablets), you may need a program or utility from the manufacturer of the devices themselves in order to use their functionality to the fullest.
For example, to enable contact synchronization between your phone and Windows, you need a program released by your phone manufacturer. To use on a computer Mobile Internet accepted by your smartphone or tablet in tethering mode, modified drivers may be required network card PC. To clarify all the capabilities of your devices and install specialized software, visit the official websites of manufacturers.
Outcome
If your computer still does not have a Bluetooth adapter, we definitely recommend that you think about buying one. With it, you can get rid of many cables and make it much easier to manage, use and configure the many devices that are already in your office or apartment.
Tell us in the comments what you use Bluetooth for Everyday life and which adapter did you choose.
Bluetooth is a wireless communication protocol between electronic devices supporting given type connections. Using Bluetooth, you can transfer various files for free, as well as support the connection of devices located at a distance of no more than 30 m.
Instruction
A fairly common question is how to turn on bluetooth on a computer. And the thing is that there is no button on the keyboard of a stationary personal computer that would turn on the wireless communication module. A laptop is more convenient in this regard. How can I turn it on and off in this case? How to set up bluetooth?
Connection
It should be noted that desktop personal computers do not include such communication modules in their default design. How then to make bluetooth work very easily: you just need to purchase a separate module and connect it. There are two types of devices:
- external;
- internal.
The first is connected via a USB port as a flash card. The second one is a little more difficult: you need to open the case system block and insert the module into the socket on the motherboard. For an unprepared user, the first option is preferable. Well, iron lovers will like the second one.
It should be mentioned that the slot into which the communication module is inserted must be of the PCI type. These connectors are usually located on the bottom half. motherboard and at the back of the case.
Driver installation
After everything is done, you need to turn on the computer. When the operating system boots, a message should appear stating that new hardware has been found. Now you need to insert the disk that should be included with the device.
This disk contains a driver that must be installed for the device to function correctly. Of course, the driver can also be found on the Internet, but for this you need to know the full name of the device. With a disk, everything is much simpler. So, now there is bluetooth on the computer. Then you can proceed to enable and configure it.
Activating the communication module on a personal computer
As mentioned earlier, the keyboard desktop computer there is no special button responsible for turning it on. But there are other ways to activate it.
It is noteworthy that by default the adapter will work all the time. So it is more likely to need to be disabled, not enabled. There are two ways to do this:
- through the "Hardware Manager";
- through the module settings.
Enable through the "Hardware Manager"
For the first method, you must first press the key combination Win + R. A window will appear where you need to write the command devmgmt.msc in the line and press Enter. The operating system will launch the required tool. Here you need to find a bluetooth device, which is most likely located among network adapters. As soon as it is found, you need to right-click on it and select the item responsible for turning it on and off. Bluetooth on the computer will be activated or deactivated.
Enable through settings
In addition, you can use the adapter on a personal computer directly through its settings. After the drivers are installed, the corresponding icon will appear in the operating system tray (lower right corner on the desktop). If you right-click on it, a menu will open in which you can see several items:
- adding a device;
- equipment overview;
- opening parameters;
- disabling and enabling the adapter;
- removing the icon from the tray.
All you have to do is select the desired action.
Adding a new device
Before you can transfer files or use the wireless connection for anything else, you need to connect the right equipment With personal computer. How to do it? Everything is pretty simple. First you need to open the adapter settings and check the box that allows you to detect this computer. In the tab " Sharing» you need to check the box that allows sending and receiving files.
Now you should enable discovery on the connected device. How to do this should be stated in the instructions for the equipment. Next, right-click on the tray icon again and select the "Add device" item.
The system will automatically search for all available connections and then provide a list of them. The user can only choose the device that he wants to connect. After selection, click the "Next" button. In accordance with step by step instructions the process is brought to an end.
Using a Third Party Program
There are also third-party developments for controlling the bluetooth module. Widcomm is one such tool. This is a simple and reliable utility for remote use of wireless devices. It is compatible with all operating system versions. Windows systems, has a Russian-language interface. In addition, it is free, and in terms of capabilities it is not inferior to paid counterparts. Through it, you can also enable and disable the adapter. Among the features:
- Work with wireless printers and faxes.
- Joystick work.
- Transfer files to mobile devices.
Users claim that the utility is a very convenient, narrowly focused product. The programmers tried to add the latest technological developments, thereby improving the quality of wireless communication. In addition, all the necessary drivers are included. Is this program necessary? Bluetooth on a computer with its help will work better, and the user will have more options than using standard tools.
Using the tips above, you can easily connect and set up a wireless Bluetooth connection on your computer.
In this article, I will try to explain in detail what to do in a situation where you have a desktop computer and you need to connect some device to it via Bluetooth. For example: wireless headphones, mouse, keyboard, acoustic system, joystick, phone, tablet, etc. There are a lot of such devices, and now there is no way without Bluetooth on a computer. In addition, such a connection allows us to get rid of a large number wires.
As you probably already know, in conventional desktop computers (in system blocks) There is usually no built-in Bluetooth. Except for two cases: an internal PCI receiver (external USB) is installed, or you have a cool motherboard with a built-in wireless module. But there are very few of them, so it is unlikely. You can see the specifications of your motherboard. Well, if your PC had Bluetooth, then you would most likely already know about it. There would be an appropriate tray icon, or an adapter in Device Manager (possibly in the form of an unknown device - when the driver is not installed).
To connect Bluetooth devices to your computer, you need to buy and install a Bluetooth adapter in your computer. Usually, these are adapters that plug into a USB port. I have one, model Grand-X BT40G. It looks like this:
Is there some more PCI adapters, they are installed inside the case of the system unit. But they are not very popular. I will not dwell on choosing an adapter, as I wrote about this in a separate article. There are a lot of them on the market. There are both cheap and expensive models. From China, in general, you can order for three kopecks. But if you plan to often use a wireless connection, connect some serious devices via Bluetooth, such as headphones, joysticks, then it is better not to save on an adapter.
If you already have an adapter, we will configure it now. If not, read the article at the link above, choose, buy and return to this page.
I will divide this article into two parts: first I will show how to connect a Bluetooth adapter to a computer on Windows 10, configure it, if necessary, find and install the driver, and connect some device. And in the second part, we will do all this on a PC with installed Windows 7.
I do not currently have the opportunity to demonstrate all this on Windows 8 and Windows 8.1, but from an older and new version this operating system (I have to enter seven and ten) there are not many differences.
Anyway, First, connect the Bluetooth adapter to the computer.
After that, we proceed to install drivers and configure.
Bluetooth on a Windows 10 PC: connection, drivers, settings
Windows 10 in this regard is generally a cool system. Why? Yes, because in almost all cases, no matter what adapter you have, after connecting, all drivers will be installed automatically, and a blue Bluetooth icon will appear in the tray. And you can immediately connect the necessary devices.
In the device manager, I immediately got the "Bluetooth" section and the adapter itself. If the adapter is not recognized and displayed as unknown device (other device), you will have to install the drivers manually. How to do this using the example of Windows 7, you can see at the end of this article.
And to connect headphones, gamepad, mouse, keyboard, or other Bluetooth device to your computer, go to "Settings" in the "Devices" section. Or by clicking on the tray icon and select "Add Bluetooth device".
Click on "Add Bluetooth or other device".
Then select "Bluetooth". The computer will start searching for available devices to connect. Our device must be in search mode. In my case, these are headphones. There is a separate button there. When they are in connection mode, the indicator flashes on them. When the computer detects our device, just select it and connect.
And if you want to connect a smartphone or tablet to your computer, then in fact mobile device you will need to confirm the connection (pairing).
Thus, you can connect absolutely any Bluetooth device.
Setting up a Bluetooth adapter in Windows 7 and connecting devices to a computer
In Windows XP, Windows 7, and Windows 8, the driver will most likely need to be installed automatically after the adapter is connected. But not always. In my case, Windows 7 itself installed the driver on my USB Bluetooth adapter Grand-X BT40G. The Bluetooth icon appeared immediately.
Here is a screenshot from Device Manager.
If the system could not recognize the device and install it, the icon did not appear, then you need to install the driver. How to do this, I will show below. And now let's connect some device via Bluetooth to a computer with installed Windows 7.
Click on the icon and select "Add Device".
A window will open that will display all the devices found by the computer. Which are on this moment are located near the computer and are available for connection. We select our device and the connection process will begin. I connected again Bluetooth headset (headphones with microphone). On which you can also talk on Skype.
When the message "This device has been added to your computer" appears, you can use it. Connect in the same way wireless mice(by Bluetooth), keyboards, phones and other devices.
In the case of headphones, you may also need to set them as the default playback device. This can be done in the playback device settings. (by right-clicking on the sound icon in the tray).
Driver for Bluetooth adapter: search and installation
It doesn’t even matter what system is installed on your computer, it can be either Windows XP or Windows 10. But if it couldn’t automatically configure the connected Bluetooth adapter, then we will have to manually search and install correct driver. There are at least three ways:
When the system cannot install a driver on a device, it is located in the device manager under "Other devices" with a yellow icon. How exactly your Bluetooth adapter will be displayed (named) is hard to say. If you didn’t have unknown devices there before, then it won’t be difficult to determine it (it will be one).
I have something like CSR 8510 A10 (looks like this is the chip the adapter is built on). Right-click on this device and select "Properties". Next, go to the "Details" tab, in the drop-down menu put "Equipment ID" and copy the first line.
Opening the site DevID.info, paste the copied line into the search bar and delete everything superfluous so that only the value of VID and PID remains. You can see what value I originally had (screenshot above), and what I searched for (screenshot below).
First, let's download the first driver that appeared in the search results. You need to click on the floppy disk icon. pay attention to operating system for which this driver is suitable.
We pass the "I'm not a robot" check, click on the link and save the archive with the driver.
If there is no installation file there, but just a set of folders and some files, then right-click on the unknown device in Device Manager, select "Update driver" - "Search for drivers on the computer" and specify the path to the folder with the drivers. If the driver is not found and installed, then try downloading another one.
I really hope that the article was useful to you, and you still added Bluetooth to your computer and were able to connect the necessary devices. And I did not waste half a day 🙂
