Positive user rating in reviews and comments in social networks, on specialized forums and other resources on the Internet, as well as recommendations on how to download the Bluetooth driver for free for Windows 10, 8.

General concept of Bluetooth technology

If you need to connect a PC to any gadget via bluetooth protocol, it makes sense to download Broadcom Bluetooth drivers for free for Windows XP, Vista, 7, 8, 8.1, 10 and put it on your computer, laptop or netbook. This technology allows you to connect to personal computer the entire range of peripheral devices and equipment with the appropriate wireless information transfer protocol and use both one-time and permanently. Of the connected devices, tablets, smartphones, mobile phones, digital photo and video cameras are most often used, wireless headphones, speakers, Bluetooth headsets for PC, bluetooth headsets for phones, Speakerphone in the car, mice, joysticks, keyboards, fax machines, printers, scanners, GPS receivers, OBD2 ELM327 Bluetooth adapter for car diagnostics and more. Multiple Bluetooth devices working on a network are called a piconet (piconet). Both point-to-point and point-to-multipoint combinations are standardly supported. Before pairing, all active parties must enter a PIN code. Passive hardware has a built-in PIN code.

Among the advantages of this technology, it is worth highlighting the following advantages:

Operational search and connection of devices,
- low energy consumption,
- resistance to radio interference,
- data transfer in parallel,
- high-quality voice broadcasting,
- 128-bit AES cipher for data protection.

Bluetooth is translated into Russian as "blue tooth". The technology has been developed since 1994 by Erickson Corporation, and since 1998 IBM, Intel, Motorola, Nokia and Toshiba have joined it, forming the Bluetooth SIG. Today, in addition to Bluetooth, such non-wire substitutes for RS-232 cables as IrDA infrared communication and Wi-Fi local radio networks have become widespread.

Bluetooth adapter and network

A BT adapter is usually a USB device that allows one PC to communicate with other PCs and other devices of the type local network with the ability to transfer data between them. Such data can be, for example, video recordings and photos from a mobile phone, melodies, documents, eBooks and other. Also, a BT connection is suitable for connecting to the Internet, for example, via 3G or GPRS, using the modem capabilities of a mobile phone. Bluetooth networks operate in the unlicensed in most countries radio frequency range from 2.4 to 2.485 GHz, where Wi-Fi, radio phones operate and emit concomitant microwave radiation, scientific and medical equipment. In the latest specifications of Wireless personal area network, WPAN, the range of bluetooth networks is increased to 100 meters, and data is transmitted at a speed of 3 Mbps. The most powerful Host XR from AIRcable hits 30 km. The scope of application has no restrictions: from the usual smartphones, headsets, GPS navigators to auto OBD2 ELM327 Bluetooth diagnostic scanner and sensors used in science, sports, medicine.

How to enable bluetooth, download and install software

Before starting the installation, you must make sure that the equipment is working: connect a working USB adapter or activate the Bluetooth module in the laptop BIOS. After the user was able to download the bluetooth drivers for free from this page of the site in Russian and started the installation, you don’t have to configure anything. Installation takes some time, sometimes you have to wait depending on the equipment. When Bluetooth starts, it automatically diagnoses the equipment and analyzes the possibility of organizing a wireless connection, determines the parameters of the peripheral device. Bluetooth equipment on a PC does not always work perfectly, so we recommend looking for a computer in a BT environment from a trusted tablet or smartphone.

How to turn on bluetooth if there are problems

If there is a problem with installing drivers, then there are two options for solving the problem. The first is to check the operability of the BT device itself, for example, the indicator is off, the computer does not detect it and does not show it in the equipment list. The second is to make sure that the USB port is working by connecting any other device to it, for example, a USB flash drive. If the USB port is working, then it is worth testing on this computer a known working BT-adapter.

As a rule, once installed Bluetooth drivers for data transmission work without problems even when changing the adapter. It is enough to download the Broadcom bluetooth software once to a computer from operating system Microsoft Windows 10, 8.1, 8, 7, Vista, XP and install correctly. Reinstalling or updating generic Bluetooth drivers is usually not required because the technology specification assumes extended hardware compatibility.

At the heart of any progress is the idea of ​​​​finishing and improving existing technologies, which means that their predecessors, in a sense, become irrelevant. But if you are faced with the question of how to choose a Bluetooth adapter for your computer, it is better to understand the essence of all the options presented.

About technology

There are quite a decent number of versions of this specification, but at the moment there are only 5 of those that were critical: 1.2, 2.0 + EDR, 3.0 + HS, 4.0 and 4.1. All the subtleties will not be presented here, but if someone is interested, he can easily find all the differences and features that were added in each version. But some things, namely transmission speed, signal strength, stacks and profiles, make sense so that you can make an informed conclusion about which Bluetooth adapter to choose for your PC.

The transmission rates for the five aforementioned versions of the specification are respectively 1, 2.1(3), 3(24), 24 and 24 Mbps. But this is only theoretical, in practice the speed is much less.

By power, the technology can be divided into 3 parts: 100, 2.5 and 1 MW. This directly affects the range of devices and gives them indicators of 100, 10 and 1 meter, respectively. However, only devices of the same standard of 2.5 MW and 10 meters can be found on the market, since samples with minimum performance are no longer mass-produced, and maximum data correspond only to gadgets that were added to Wi-Fi boards with PCI- connectors and in a separate form simply do not exist.

It is also worth noting that the basis of all Bluetooth technology is a wireless analog of the RS-232 cable, on which various protocols for the execution, transmission and management of information and available resources, which are called stacks, are “hung”. These stacks are required, without which the whole layered architecture simply will not work, and optional, allowing you to apply improvements to existing functions, as well as add new ones.

The main stacks include 5 units:

There is also such a thing as "Profiles", which are directly related to which Bluetooth adapter for a PC is better to choose. There are many of them, but it makes no sense to consider everything, since most of them have specific functions. But nevertheless, we will consider some situations, as this will help to make the right choice.

Adapter selection

So, which USB Bluetooth adapter to choose depends directly on the purpose for which it will be used. In turn, the functionality of a particular module is determined by the previously mentioned profiles, which manage the stacks to obtain some specific parameters.

For example, consider a situation in which a client wants to access the Internet through a Bluetooth module. In this case, he will need a model that supports the Dial-up Networking Profile (DUN) or LAN Access Profile (LAP). If he tries to distribute the network via a Bluetooth module from an ordinary wireless mouse, then he will not succeed, since the Human Interface Device (HID) profile is used in the manipulator. And it will be the same with the transmission of an audio or video signal, where the Advanced Audio Distribution Profile (A2DP) will be needed.

Another example defines the desire of the owner of the device to control the PC using a mobile phone or TV remote control. If the Bluetooth module does not support Audio / Video Remote Control Profile (AVRCP), but is focused on working only with Hands-Free Profile (HFP) or Headset Profile (HSP), then it will not work to make the sound louder, but connect a headset or mobile phone for calls - in two counts.

In general, the essence is this: before looking for the right device, you will need to determine its functional purpose and only then start choosing the right equipment. Since there are devices of different sizes, purposes, capacities, data transfer rates, and even options combined with a Wi-Fi module that have antennas and without them. By the way, the latter differ among themselves in terms of signal strength and operating range.

If someone is interested in how much a Bluetooth adapter costs, then the answer directly depends on the functionality, as well as supported profiles and stacks. specific model, version, capacity, purpose and form factor. But, in general, the price varies from a dollar to a hundred, or even more, since you should not forget about such nuances as build quality, parts and materials used.

How to find out if Bluetooth is on your computer: Video

Bluetooth adapters are modern useful gadgets for creating affordable wireless communication between various devices: tablets, mobile phones, smartphones, laptops, PCs, speakers and TVs. Adapters create a reliable connection for the quick exchange of useful information, files and work commands.

Stable and high-speed wireless connection protocol - Bluetooth. The choice of adapter directly depends on the specific tasks for which it is intended.

Peculiarities

Consumers often confuse two similar terms - Bluetooth and Wi-fi connection. While Bluetooth technology is used to transmit data over short distances between different devices, Wi-fi technology is used to create a local computer network and organization of remote access to the Internet.

The maximum range of adapters is 50-60 meters, so they are used in apartments, houses, offices and shops.

This technology is used to quickly exchange audio, video and text files, you can manage RAM, send and receive photos, manage work programs.

The module is connected without additional cables and adapters, via a standard USB port. The advantage of the module is the ability to transfer data at high speed. Modules are able to install and maintain wireless communication even with short-term wave interference occurring between devices.

Types of Bluetooth adapters

Modern electronics are made with installed module, however, there is equipment that requires the use of additional equipment due to its design and technical features.

Bluetooth modules are presented in two types - internal and external. Each of them differs in functionality and installation method.

Internal

This type of device is motherboards, which are connected directly to the internal circuitry of the reader. They are reliable, durable, but difficult to install. They are used for stationary PCs, laptops and speaker systems.

External

By design features, it is similar to USB drives - it is installed in any USB port. The module is suitable for modern electronic gadgets, television and video equipment.

Ergonomic housing, ease of installation and safety of operation, combined with an affordable price, make such devices indispensable for creating local wireless networks and performing tasks of any complexity.

Characteristics of bluetooth adapters

Bluetooth-based connection technology is represented by 5 versions. Each version provides its own data rate, working signal strength, stacks and profiles.

• 2.0+EDR;
• 3.0+HS;

The transfer rate of operational data is 3-24 Mbps. Power technology has the following parts: 1; 2.5 and 100 MW. This indicator affects the coverage radius with similar indicators. The unit of measurement is meter. Devices of 1 MW with a range of 1 meter. Devices with a capacity of 2.5 MW are presented on the market, with an exposure radius of up to 12 meters.

The latest version of the equipment in 4.1 provides coverage with a radius of up to 60 meters.

When choosing a device, you need to consider the power and range.

Working connection profiles

Profiles are functionality that is supported by various hardware.

Bluetooth technology supports the following profiles:

• gap- is intended to maintain the operation of other profiles, the security of the wireless connection.
• A2DP– designed to transmit audio signals in a two-channel stream. It is necessary for the exchange of audio files, listening to music.
• HSP– used for wireless connection of a headset (headphones, microphone) – mono sound transmission at a speed of up to 64 Kbps.
• AVRCP– used to control sound on playback devices.
• LAP- intended for the organization wireless network between two Bluetooth devices.
• DUN– the profile allows you to use your phone as a modem.
• HID– headset connection – computer mouse and keyboards.
• OBEX FTP– profile to connect to random access memory mobile and tablet technology from a laptop or PC.

Even if the transmitting and receiving devices support working with protocols, the codecs used are taken into account when choosing bluetooth equipment.

In a couple of reviews, I already wrote about this thing (,), today let's talk in more detail about what it is and why you might need it.

If you have a laptop, then you most likely do not need this thing, because they are built into them by default. But if you have a regular desktop computer, and even quite ancient, then a bluetooth adapter can be very useful to you.

And you need it in order to connect various bluetooth devices to your computer, for example, the headsets mentioned above, or even wireless joysticks, in order to play various games on your PC with their help, or, for example, flip through tracks in the player and even put on a movie pause.

My new bluetooth adapter for computer

I bought such a usb bluetooth adapter just for such purposes:

• Connecting headphones to a PC (what came of it -)
• Connecting joysticks to a PC for playing various racing games, fighting games or even emulators of Dendy and Sega consoles. And it really works.
• You can also use the joystick as a control panel, and this also works, but I'm lazy to keep it connected all the time, so somehow it didn't grow together.
• Also, with the help of such a bluetooth “whistle” (and I call them that), you can connect your phone to your computer and, for example, transfer files back and forth, upload photos, music, and so on. I will not dwell on this in detail, because the Web is full of manuals on how to do this.
• There are also all sorts of peripheral devices that can be connected through this thing, for example, mice, keyboards and more. But, as a rule, such adapters are already included with them.

If any of the above is of interest to you, then you can safely read the article further.

Where to buy a bluetooth adapter for a computer

Yes, we will look for them again on Aliexpress, and then I will show my model. The requests are quite simple: usb bluetooth , usb bluetooth adapter and everything like that. There are herds of them here, as expected, and they cost a penny. But - be careful. Depending on what device you will connect via bluetooth, it is desirable that the versions of the whistle and the device match. For new devices, you need a four, for old ones, twos and threes.

Search for these things on Aliexpress

For example, my headphones and headset need 4th bluetooth, joysticks need the same. Yes, it all works with both two and three, but the contact may not be stable. Likewise, most of the new modern phones has built-in bluetooth 4.0 or even bluetooth 4.1. So be careful. If you have a new device, then you need bluetooth 4 and higher (most likely, but in general - see the instructions and standards).

By the way, while I am writing this post, I found several models in which there is already the 4th bluetooth (it seems to be), I feel that I will have to order some of this for myself. For example, whistle for 285 rubles, there is even a local delivery, but it is paid - 180 rubles. In addition, at the time of writing, it is not available. But more than 7400 orders and very good feedback. I ordered in general, as it arrives — I'll tell you right there).

And he arrived, and he turned out to be cool, in the sense that they finally worked normally with him, hooked up to a PC. So yes, it was the version of the receiver.

My third Bluetooth adapter U-Green

Here are some more things like this: 222 rubles, 6600 orders and good reviews. Or here: 221 ruble, 700 orders. Well, you get the idea, packs of them are here.

My video review on Usb bluetooth adapter for computer UGreen

My unnamed bluetooth adapter for my computer

I took it, mainly for. An old whistle, probably the second version, was presented to me several years ago (and it seemed to cost something around 1100 rubles), but I never began to use it, because even sending photos from the phone through it takes a very long time. Although - it still works, what will happen to him. But the second version of bluetooth is very slow.

Photo of an old whistle

With headphones, he stutters about like a new one, but first things first.

I ordered my new whistle already on June 29, 2015, for as much as 2.5 bucks, at that time it was somewhere around 110-120 rubles. I bought where they are no longer there, but above I gave links where you can find something similar. Strange thing - this store now generally sells some kind of cosmetics).

How did it ride

I can’t even say how long he traveled, because he was not tracked, there was the same digital tracker that not all services see. But it seems to be something within a month.

Unboxing

But I didn’t even take it off, apparently, I was too lazy to do it for a thing for a hundred rubles. Well it looks like this:

Another photo of a whistle compared to a 10-kopeck coin

Work and testing

As I wrote earlier, he is not very friendly with headphones, because they have the fourth bluetooth, and here it is only the third, although compatibility with the four is declared. Pay attention to the standard, and not to compatibility, that's what I pricked:

Pay attention to the standard, not to compatibility

Under number 1, we see that everything seems to be fine. But under the number 2 - we see only the third bluetooth. Don't make my mistakes if you have new devices. Those links that I gave above - they already seem to have exactly four, you will have to try to order, then you can still make your ears work with a computer. It is correct to work, because they work anyway, only at times they stutter or accelerate. What does not happen if you pair them with a phone where there is just the 4th bluetooth.

Summarizing

On this, in general, everything. Now you know where to buy a bluetooth adapter for a computer inexpensively, and you also know that they are different. And if you save too much, then it can go sideways.

box with everything

Now this adapter as a whole is idle, but sometimes I still connect a joystick through it - to play something. He is quite good at this. And thanks for that - for a thing for a hundred rubles, this is something.
