Communication between phones via bluetooth. Connecting your phone via Bluetooth. Features of connection on Android

Is a wireless technology that allows you to create wireless secure local networks, making this technology ideal for short-range connections between devices such as a phone and an infotainment system, or between a phone and a Bluetooth hands-free system found in cars.

The process of creating a network connecting a phone to a car is called “pairing” or “pairing” (since the network consists of only one pair of devices). Although one Bluetooth device can theoretically be connected to several other systems and gadgets, each connection is secure and unique to one specific pair of devices.

In order to successfully pair a cell phone with a car's infotainment system, both devices must be Bluetooth compatible.

Most car entertainment systems are equipped with Bluetooth wireless technology, which is compatible with most mobile phones on the market.

This allows the driver to create a wireless communication channel in the car, which provides hands-free operation with which you can receive and send calls from a mobile phone without taking your hands off the steering wheel. Also, connecting a phone to a car allows the driver to receive and send messages, listen to his favorite music from the phone on the car’s audio system, and even access the Internet using mobile Internet from the car’s screen.

1) Check your equipment for Bluetooth compatibility

In order to use your mobile phone in the car using a public address system you need to:

• - Bluetooth enabled cell phone

• - Infotainment system or car audio system with Bluetooth support

• - PIN number for infotainment or audio system

Also, connecting your phone in the car is useful have the following things:

• - Car phone mount

• - Charger 12 volts for cell phone

2) Make sure your phone's Bluetooth is turned on

Most mobile phones and smartphones have Bluetooth technology. But, nevertheless, before connecting your mobile phone to your car, you should check the availability of wireless technology.

The exact process for pairing your phone with your car's audio system depends on the make and model of your phone and your car's infotainment system. Therefore, in this guide we will use universal tips to help you connect your phone to your car, regardless of its type, brand and model. However, when connecting your phone to your car, make sure you use correct settings Bluetooth by reading the machine's manual.

And so, in order to connect your phone via Bluetooth to your car, you first need to make sure that the system is activated on your phone. To do this, you must find a menu in the mobile phone settings that is responsible for enabling/disabling wireless system Bluetooth data transfer.

If you don't know where Bluetooth is turned on on your phone, check the device manual for details on how to turn on the wireless system.

When you find a function in the phone menu that activates or deactivates the Bluetooth system, you should also make sure that the “phone detection by other devices” option is turned on on the phone. Depending on the make and model of your phone, you can also set the visibility time of your device for other devices. For example, you can set your phone to be visible to other devices for only a few minutes.

Some phones can be configured to make the device visible at all times.

Also, in some mobile phone models, the Bluetooth system automatically turns off after a few minutes of searching for other devices, if no external connection has been made during this time.

3) Make sure your vehicle's infotainment system is ready to connect to your phone

Many cars have a button (TEL, Phone, Bluetooth and others), which, if pressed, will begin the process of connecting the car with the phone. In some vehicles, the process of "pairing" the phone with the car can be initiated using a voice command. There are also many cars in which the process of connecting a mobile phone to the infotainment system is started by activating a special function in the menu.

In our example, we will look at the most difficult option, when in order to connect your phone to the car you will have to use the menu on the screen of the car infotainment system.

We would like to note that if you do not find a Bluetooth button in your car or your car does not support voice commands, then you will have to look in the car manual for a section that talks about connecting your phone to the infotainment system or setting up audio transfer from your phone to the car's audio system.

4) Search for your phone by the car's infotainment system

You should only proceed to this step if your phone's "visible to other devices" option is enabled, Bluetooth is activated (if you want the infotainment system to detect your mobile phone) and the "search" function is working on your phone. devices" (if you want the phone to find the infotainment system).

However, no matter which device you want to enable searching for connected equipment, both systems should be ready to search for a connection within 2 minutes.

In our example, we used the car's infotainment system to search for a phone. To do this, we found the Bluetooth icon in the entertainment system menu and clicked on it to start searching for a cell phone via a wireless communication channel.

5) Search for car infotainment system on your phone

If you want to connect from your phone, then you must activate Bluetooth and launch the “search for devices” function. The phone will then begin scanning the network for all visible Bluetooth devices.

So don’t be surprised if, after searching, you see various wireless devices (laptop, someone else’s computer or other people’s phones) on your phone screen.

After searching for devices, your task is to select your infotainment system or your speakerphone system on the screen.

6) Select your car's speakerphone from the list of detected Bluetooth devices

After the phone has detected the hands-free system of your car, on the device screen you will find a “Hands Free” system or the like in the list of detected equipment available for connection.

In our example, I discovered the “Hands Free” system of the Toyota Camry. After this, in our example, you had to click on the “Hands Free” inscription to begin the process of connecting the phone and the car.

After you select on the phone screen required device To connect (or after the infotainment system detects your phone), you will need to enter a password (PIN) on your phone to pair the devices.

As a rule, all cars equipped with a speakerphone or a system for listening to music with wireless devices, come with a password generation system for pairing the car with the phone.

If your car is equipped with an infotainment system screen, then after the devices find each other, a password should be displayed on the car screen, which you must enter on your mobile phone to finally pair the devices.

If your machine is not equipped with a screen, but has a hands-free option, then refer to the manual for vehicle, which should indicate what password must be entered to connect the phone to the machine.

Modern radios are able to communicate with a smartphone using wireless technology - Bluetooth. Moreover, this can be either a standard device or a separately purchased device. Thanks to the connection via Bluetooth, it is possible to receive incoming calls and also play music directly from the phone. Let's figure out how to connect a smartphone to the radio correctly.

Before you start pairing devices, you need to activate the Bluetooth function on your phone. This is done through the settings or the notification shade. The second method is faster, but is only suitable for previously connected devices.
First of all, let's go to settings. Here we go to the “Bluetooth” tab.

In the window that opens, move the slider to the right.

Some phones require the visibility feature to be activated. If this is not done, the radio will not be able to find the connected device.

Step 2: Turn on the radio

On most popular radio models there is a button " Bluetooth", "Phone" or "Tel". By clicking on it, the smartphone will automatically connect to the device, which will be indicated by the appearance of an inscription in the list of connected gadgets.

There are times when the player cannot detect the smartphone. In such a situation, you can try to reboot the device and radio. If the situation does not change, then try connecting another phone. If there are no problems connecting it, then most likely your smartphone has some problems with Bluetooth.
On touchscreen players, pairing is even easier. Just go to the menu and select “Bluetooth”. A list of available devices should appear on the screen, from which you need to select your phone model.

Step 3: pairing

The most convenient way is to connect your smartphone to the radio directly from the Bluetooth settings. To do this, turn on Bluetooth, where from the proposed list select the audio system model. Now a pairing message will appear on the player screen, where you need to enter the password from your phone in the appropriate field. If the radio does not have a display, then the desired combination is entered using special keys, the meaning of which can be read in the instructions.
Now it's possible to play your favorite songs directly from your phone's library. Please note that all downloaded music must be in MP3 format, otherwise an error will occur.
Not many people know, but you can add bluetooth to a regular radio with a USB input. A special Bluetooth module, which looks like a flash drive and connects to a USB connector, will help with this. It is worth noting that the cost of this gadget is only 5-10 dollars.

Conclusion

As you can see, connecting your phone to the radio via Bluetooth is very simple. The principle of operation is the same as when pairing any other device. The main thing is to be attentive and careful!

Prices Mobile Internet in 3G and 4G networks have almost descended from sky-high heights to earth and soon, we can expect, will equal the cost of traditional cable communications. And then, you see, they will push it out completely, because using the Internet, which you always have with you (in cell phone), much more convenient than being tied to its stationary source.

Switching from landline Internet to 3G/4G is a matter of a couple of minutes. It is enough to have an agreement with mobile operator(access to the global web today is included in almost any tariff plan) and a certain amount on the balance sheet. Well, the mobile phone itself, which will be the connection point.

Let's talk about how to connect the Internet to a computer using an Android smartphone as a modem.

Phone as a modem via USB cable

Connecting to the Internet through a phone connected to a computer via a USB cable is perhaps the easiest way. This method is convenient because it does not require settings and does not require measures to protect against hacking and unauthorized access, like wireless communications. The connection is established in a matter of seconds and works almost flawlessly, of course, provided there is a good signal cellular communications and a high-quality USB cable.

Procedure:

• Go to the Settings app (in older Android versions- “Options”), open the section wireless networks, go to the advanced wireless settings (in my example, they are hidden behind the “More” button).

• Turn on “Mobile data”, that is, connect the phone to the 3G/4G Internet network. Or do it in another way - by pressing a button in the curtain, etc. On different Android smartphones, this and subsequent actions are performed slightly differently, but the essence is approximately the same.

• Being in additional parameters wireless networks, open the “Modem Mode” section. Move the “USB tethering” slider to the “Enabled” position.

The setup is complete and the connection is established. Your computer is now connected to the global network via a USB cable and network mobile operator.

Bluetooth modem on your phone

If you want to connect devices equipped with a bluetooth module (laptops, smartphones, tablets) to the network, you can use your phone as a bluetooth modem. To establish a stable connection, client devices should be located no further than 8-9 m from the phone, but best of all - in close proximity. Also, make sure that the Bluetooth adapter is activated on all devices.

The procedure for connecting to the Internet via a Bluetooth modem on your phone:

• Turn on 3G/4G Internet on your phone.
• Go to the Settings app - Wireless & Networks. Slide the Bluetooth slider to the On position.

• Go to the “Bluetooth” section and select from the “Available devices” list the device to which you want to provide access to the World Wide Web. If there are several of them, establish the connection one by one. When windows appear asking for permission to pair, check the code and click the “Connect” button on both devices to be connected.

• Open the “Modem Mode” section in the additional wireless network settings and turn on the Bluetooth modem.

Now your gadgets have access to global network. By the way, you can simultaneously continue to use your phone as a modem connected to your computer via USB.

Creating a Wi-Fi hotspot on an Android phone

To connect the Internet to a laptop, tablet, smart TV and other devices that are located in different parts of the apartment, it is most convenient to use Wi-Fi. And our smartphone will again be the access point and modem.

The procedure for setting up an access point and connecting to the Internet:

• Turn it on on your phone Wi-Fi module and 3G/4G Internet.

• Login via additional settings wireless networks in the “Modem Mode” section. Tap the "Point" line Wi-Fi access».

• In the “Wi-Fi Access Point” section, move the slider shown in the screenshot to the “Enabled” position. Before connecting devices to it, you need to make a few more settings.

• Tap the “Save access point” line. In the window that opens, select the appropriate option. To save battery energy, it is optimal to turn it off after 5 or 10 minutes of inactivity. If the phone is constantly connected to a power source, then the access point can be saved forever.

• The next setting is the network name, encryption method and password. The name (by default it usually repeats the name of the phone model) can be anything. The best way protection (encryption) - WPA2 PSK. If you are going to connect an old device, for example, a laptop with Windows XP, to this access point, choose WEP protection. Next, set a password that users will enter when connecting client devices, and save the setting.

• To communicate with devices equipped with a WPS button, you can use the same function on your phone. First, click WPS on the client device, then click the “Connect” button shown below on the phone.

After this, your gadgets will have access to World Wide Web via Wi-Fi. By the way, if you wish, you can use all 3 connection types together, but with a very intense load on network modules the phone will heat up (which is clearly not good for it) and, despite being powered from the computer via USB, will quickly use up battery power. Therefore, it is still not worth loading it to the maximum. For such cases, it is better to use a traditional cable Internet connection.

How to connect your phone to a computer via Bluetooth? This question comes up quite often. The point is that thanks to modern technologies we can transfer files from mobile to PC freely. And this is done without using any wires.

There are many different technologies wireless communication, but Bluetooth is the most widespread. Despite the fact that this connection is quite old, it still does not lose its relevance today. It has a lot of advantages. Eg:

• Noise immunity.
• Easy to use.
• Cheapness.

In other words, this technology is extremely simple and understandable for everyone, and at the same time it is accessible to absolutely everyone. But how to use it?

Pairing devices

You should also enable detection on your mobile phone. It is worth noting that on Android smartphones this function is activated for a certain time (about 2 minutes). In other words, after enabling detection on your smartphone, you need to be able to find it on your PC in no more than 2 minutes.

So, we turned on the adapter and detection on the smartphone. Now right-click on the Bluetooth icon in the PC system tray. Select "Add device".

As a result, a window will open in which a list of available connections will be displayed. Select the name of your mobile and click “Next”.

After this, a message with a code will appear on the laptop. This code must match the one that appears on the smartphone. If everything matches, then confirm it on both devices.

• Transfer files.
• Use PC to play music.
• Use as a headset and so on.

To do this, right-click on the Bluetooth icon (in the PC system tray) and select “Show devices”.

The answer to the question of how to make a Bluetooth adapter from a phone is a kind of “cheat” that transmits a Bluetooth signal over the Wi-Fi network. This technique can come in handy in the most unexpected situations. The method can be applied in this case:

• There is no Bluetooth adapter on the PC: neither external nor built-in.
• You have a Bluetooth device: speaker, keyboard, gamepad.
• You have a smartphone.

In this article I will tell you how to use your phone as a Bluetooth adapter for your PC so that you can use your gadgets without purchasing a separate module.

Step-by-step instruction

A smartphone as a Bluetooth adapter can help you out in some difficult or urgent situation when there is no way to buy wireless adapter. Sometimes this is an opportunity to save money or find a use for an old smartphone.

• You will need a computer, a Bluetooth device that we will connect and a phone as a Bluetooth adapter for a PC. You also need a Wi-Fi network: both a computer (you can wire it to a router) and a smartphone must be connected to it.
• If you don’t have a router, you can create a network directly on your phone. To do this, find “Modem mode” in the settings (sometimes hidden in “More”) and turn on the Wi-Fi access point. In the access point settings, you can specify the network name and password. Connect your computer to this network. To do this, you will need a Wi-Fi adapter on your PC.

• Now you need to decide on the gadget that you need to connect. Depending on its type, different programs can do this. For all cases, one application is installed on the computer, the second, from Play Store– on a smartphone:
  • for Bluetooth speakers, headsets, headphones: soundwire-server (computer) and SoundWire free (phone);
  • for gamepads: kinoconsole (computer), KinoConsole (phone);
  • PC Keyboard (computer) and PC Keyboard WiFi & Bluetooth (phone).

The latter option is still at the Beta stage and only works on the English keyboard. The option for speakers and headphones works best. Therefore, further I will describe working with him. For a gamepad and keyboard, working with applications will be similar.

• Launch both apps on your devices.
• On your PC, select the audio device from which sound will be transmitted to the Bluetooth gadget. You will also need the IP address listed here.

• IN mobile application start by checking your settings. Go to settings using the menu in the top right corner.

• In the “Audio buffer size” item you need to set the value to “128” - this is the optimal value, tested by other users. Also check Wake Lock so that the program does not turn off when the screen dims.

• Return to the main screen and enter the IP address specified in the program on your PC. This is the main step to connect any device and will also be needed in the other programs listed above.

• Now you need to simply click on the application icon (spring) and the sound from the computer will be broadcast to the smartphone.

• Now connect any audio device to your smartphone: speaker, headset or headphones. Turn on Bluetooth on your phone and activate the pairing button on your gadget. Select it from the list of available connections. When pairing is established, you will hear sound from the PC on the speaker (headphones).

Conclusion

Problems associated with this method include a slight delay in sound or the “dampness” of some solutions, such as with the keyboard. When you know how to use the phone like bluetooth adapter, then you can find proper use for your old smartphone. For example, this is how you can make a broadcast big music library from PC to external wireless speaker. There are a lot of options for using the method.

Having completed the setup once, you will only need to repeat the application on your PC and phone, confirm the IP address and turn on the speaker. All other steps will be completed automatically. I hope you enjoy the savings and convenience wireless technologies thanks to this method.
