What functions does Bluetooth have?

Question 1: What is Bluetooth used for? Bluetooth wireless technology is a low-cost, low-power, short-range radio frequency wireless technology used for mobile devices and WAN/LAN access points. Currently, more than 2,000 companies support and adopt Bluetooth technology. This fact illustrates that Bluetooth is quickly becoming one of the widely accepted low-cost wireless technologies for personal area networks (PANs). Bluetooth technology makes it possible to transmit short-distance signals between broadband access devices, phones, PCs, information appliances and other devices.

When it was first launched, Bluetooth technology was very slow to be adopted. However, as the technology field develops and more and more manufacturers in the fields of digital consumer electronics, mobile phones and automotive electronics produce products that support Bluetooth , will surely arouse more consumers' interest in this technology and gradually understand the benefits brought by Bluetooth technology in the era of wireless communication.

Bluetooth technology is a short-range wireless connection technology used to replace cables or wires used on portable or fixed electronic devices. Its equipment uses the globally accepted 2.45GHz frequency band that does not require a license, and can transmit data and voice in real time. Its transmission rate can reach 10Mbit/s. It supports 3 voice channels and also supports data transmission up to 723.2kbit/s. rate. In other words, in the office, home and travel, there is no need to lay special cables and connectors between any electronic devices. A point-to-multipoint connection can be formed through the Bluetooth remote control device, that is, a "micronet" is formed around the device. , any Bluetooth transceiver in the network can communicate with the device.

Question 2: What is Bluetooth function? 5-point introduction to Bluetooth function

First, let’s talk about several main Bluetooth standards

1. Address book

Almost all Bluetooth mobile phones can transfer to the Outlook contacts of the computer.

However, only very few of the Outlook contacts of the computer can be transferred to the mobile phone.

2. Communication transmission

In fact, this is the Internet function, which is supported by all Bluetooth mobile phones. The role of mobile phones can be considered to be equivalent to that of cats.

The other is GPRS on WAP network.

This is also a GPRS mobile phone that supports GPRS, a WAP mobile phone that supports WAP, and a CDMA mobile phone that supports CDMA

3. Fax

This function may be rarely used because mobile phones There is a service fee for adding the fax function

4. Bluetooth headset

There is nothing special about this, it is supported by all.

Bluetooth headsets were born for Bluetooth mobile phones.

It’s just that the price is a bit more expensive and there’s no way around it

5. File transfer

Most mobile phones support file transfer, but most of them transfer files from the mobile phone to other devices. The Bluetooth device supports FTP file transfer from PDA and computer to mobile phone.

6. Serial port service

This is hard to say, many functions can be realized through the serial port

For example, a Bluetooth mobile phone can control a computer, or connect to the network, etc.

This can actually be called an extension of existing functions.

Aren’t there many data cables with S port~~~

7. Mobile phone service

There are really not many mobile phones that support this function

Perhaps Sony Ericsson models have more support. Through this function, you can not only send text messages with computers and PDAs

but also make calls very smoothly, representing the MP of software PDA

Now let me compare my three Bluetooth mobile phones S65

The first one is X11, but it is Panasonic’s earliest version of Bluetooth mobile phone

They all support the simplest Bluetooth

For the mutual transmission of files, the function is not as good as infrared

However, Bluetooth transmission speed is very fast and the protection is very safe

Normally, if you don’t accept files, you won’t be able to On, the communication function is very good for transmitting with smart Bluetooth phones such as SX1

The second one is S55, which is Siemens’ first Bluetooth phone

It is more comprehensive in terms of functions Almost all the functions I mentioned above are available

and FTP files can be supported on the mobile phone.

That is, I can directly use a computer or PDA to control the file management on my mobile phone.

And it is very convenient to send various files in my device to my mobile phone

The third one is S65, which supports stronger email capabilities

But it is different from the S55 Bluetooth is relatively similar and does not support more functions.

Bluetooth is a short-range wireless connection technology used to replace the use of cables or wires on some electronic devices. The use of "Bluetooth" technology can effectively simplify the communication between mobile communication terminal devices such as handheld computers, laptops, and mobile phones, and can also successfully simplify the communication between the above devices and the Internet, thus making the connection between these devices and the Internet Data transmission between networks becomes faster and more efficient. Currently, there are many models of handheld computers with Bluetooth function. I believe that with the gradual development of handheld computers, Bluetooth function will become a common function of handheld computers. But at present, handheld computers with Bluetooth function are relatively expensive.

Using the Bluetooth interface of a handheld computer to connect to other devices that also have Bluetooth interfaces can also achieve wireless connections. It has no directional restrictions, the effective connection distance is up to 10 meters, and the general transmission speed is 1M, fast Up to 10M or even faster, etc., but currently there are not many electronic devices equipped with Bluetooth interfaces, and there is a big gap with the popularity of infrared interfaces. This is a pity. However, computers without Bluetooth interfaces can pass Install a Bluetooth adapter to realize the Bluetooth interface function. These Bluetooth adapters are generally USB interfaces and can be plugged into the USB interface of the computer. They are only the size of a flash drive and are much more convenient to carry than a data cable. ...gt；gt;

Question 3: What does mobile phone Bluetooth mean? What are its functions? Bluetooth is the name of a wireless transmission tool! Can realize wireless transmission of text, pictures, videos, software, etc.! It must be kept within 100 meters to be effective!

Question 4: What does Bluetooth mean? What does it do? Bluetooth is a low-cost, high-capacity short-distance wireless communication specification. A Bluetooth laptop is a laptop with Bluetooth wireless communication capabilities. The name Bluetooth also has a legendary story. In the 10th century AD, when the Nordic princes were fighting for hegemony, the King of Denmark stepped forward. With his unremitting efforts, the bloody war was stopped and all parties sat at the negotiating table. Through communication, the princes settled their differences and became friends. Because the King of Denmark loved eating blue plums so much that his teeth were dyed blue, he was known as the King of Bluetooth. Therefore, Bluetooth has become synonymous with communication. Today, a thousand years later, when the new wireless communication specification was introduced, people named it after Bluetooth.

In 1995, Ericsson first proposed the Bluetooth concept.

The Bluetooth specification operates in the microwave frequency band, with a transmission rate of 1M bytes per second and a maximum transmission distance of 10 meters. It can reach 100 meters by increasing the transmission power. Bluetooth technology is globally open and has good compatibility around the world. The whole world can be connected through a low-cost invisible Bluetooth network.

Bluetooth technology is not only used in computers. Many electronic devices such as mobile phones, digital cameras, camcorders, printers, fax machines, home appliances, etc. can use Bluetooth technology to achieve wireless connectivity without having to drag a line. Tail (connecting line). With the popularization of Bluetooth technology, you no longer have to worry about the wiring of electrical appliances when decorating your home. When using home appliances, you don’t have to worry about a lot of remote controls. A mobile phone or a car key can handle everything; when you are away from home, you don’t have to worry about a lot of remote controls. The company's work schedule and pictures of family members at home can be obtained anytime and anywhere; there is no need to queue up to check in and pay, and it can be easily completed by passing near the payment point without entering the door... The widespread application of chicken tooth technology will make our lives extremely easy.

Bluetooth connection between mobile phone and computer: (Take Sony Ericsson as an example)

First, correctly install the driver of your Bluetooth adapter on the computer (I won’t go into details here, if you don’t understand, please (Refer to relevant information)

[Pairing]

Plug in the adapter so that it is connected. The Bluetooth logo in the taskbar should change from red when stopped to white when connected.

Enter the phone menu - Connection - Bluetooth - Matching device - Add device, and then the phone will start to search for surrounding Bluetooth devices. Your Bluetooth adapter will be found in a while, select your search When you arrive at the device, enter the identification code (you can decide it by yourself, as long as you enter the same thing on both sides. I usually enter 4 zeros for Sony Ericsson). After confirmation, the computer will prompt you to enter the identification code. After entering the identification code just now, the two devices will be connected. Paired.

[Computer-gt; mobile phone]

When transferring things to the mobile phone, you can only transfer files that can be recognized by the mobile phone, such as: picture-jpg; theme-thm; Audio-mid, amr; JAVA-jar, game-mpn, etc.

Keep the mobile phone’s Bluetooth and Bluetooth adapter paired and turned on. Select the file you want to transfer, right-click the mouse - Send to - Bluetooth, select the device and confirm to send. The mobile phone will prompt The name and size of the transmitted file are asked whether to receive it. Sometimes it is automatically received without asking. This is related to the settings. After the acceptance is completed, the phone will automatically store it in categories.

[Mobile->Computer]

When sending something from the mobile phone (it must be paired before), select the file to be sent-More-Send-via Bluetooth , then select the target device and send it.

Note: Sony Ericsson mobile phones can only send pictures-jpg; audio-mid, amr; themes-thm. Others such as JAVA-jar, game-mpn, etc. cannot be sent.

Question 5: What is Bluetooth? What is it used for? 5 points 1. Wireless short-distance transmission is Bluetooth. Its transmission distance is about 10 meters. In order for a Bluetooth-enabled mobile phone to function as a Bluetooth device, it must be connected to a Bluetooth-enabled device.

2. You can listen to the music played on your mobile phone through wireless headphones.

3. Connect to another Bluetooth phone to transfer songs, pictures, etc. to each other.

4. Bluetooth mobile phones can also be connected to computers, but the computer is required to have a Bluetooth adapter.

Question 6: What are the functions of Bluetooth headsets? At present, Bluetooth technology is most widely used in daily life on mobile phone call devices that support Bluetooth, such as mobile phone Bluetooth headsets. Bluetooth makes driving safer. Many car owners find it inconvenient to answer calls while driving: holding one hand on the steering wheel, Holding the phone with the other hand to answer the phone not only hinders shifting and affects safety, but also has to look around for the police with both eyes on the car in front. 12 points is really not punishable. It is more convenient to answer the phone with the car's hands-free system, but it is inevitable Inconvenient phone calls come in at inconvenient times; using wired headphones is not very pleasant either. The headphone cables swing around and affect the movement of the arms. The shielding effect of the headphone cables is poor and they are often interfered by electromagnetic noise. The mobile phone thrown on the passenger seat is often left behind. While driving, the headphone cord got caught in my clothes and fell to the ground... It made me so angry that I accidentally burst into tears at my injured car.

Bluetooth headsets used with mobile phones can make these worries go away and make driving safer. Through earbuds equipped with Bluetooth function, mobile phone users can achieve wireless hands-free function without having to hang a wire from the head to the mobile phone as now. Users can also use their mobile phones through in-vehicle Bluetooth communication devices and make calls without taking out their mobile phones from their bags.

In order to promote its Bluetooth technology, Sony Ericsson even launched a sophisticated Bluetooth remote control car - Car100. Car100 has a built-in battery but does not come with a special charger. Charging is done using a Sony Ericsson mobile phone, and the charging process is actually charging the mobile phone's power onto the Car100. Through the cockpit, you can see the control chip inside the Car100, showing a strong technological flavor.

Four-point usage guidance

1. Drivers who use Bluetooth headsets will feel very free. Whether you are looking back when reversing, or reaching back to pick up something from the back seat after parking, it is very convenient to answer calls while driving without any worries;

2. The voice quality of Bluetooth headsets is good, and sometimes it is even better than answering the phone directly. The call effect is still clear.

3. It will be a little uncomfortable to wear it at first. It may be that the user plugs the earplugs too tightly, making it seem like there is something between them and the surrounding sounds cannot be heard clearly. As long as you pull the earplugs apart slightly and lightly buckle them on the ear holes, this problem will disappear.

4. Disclose a method to ensure the call effect - always keep the Bluetooth headset and the mobile phone on the same side of the body. This way the call effect is best. That is, if the Bluetooth headset is hung on the right ear, the mobile phone can also be placed on the right ear. Place on the right side of the body; vice versa.

Question 7: What are the functions of Bluetooth headsets? Bluetooth headsets are mainly used to answer or make calls, and secondly to listen to songs. Here are several ways to wear different Bluetooth headsets.

First, let’s talk about how to wear a pair of earphones: Find the letters R and L marked on the two earbuds, wear the one marked R on the right ear, and the one marked L on the left ear. If you still have a small clip, you can clip it to the appropriate location on your clothes to secure it. If there is a tightening slider, you can move the slider to the appropriate position to tighten the headphone cable, which can also fix it. There are also earphones with different lengths of wires connecting the left and right ears. Wrap the long one around your neck, string the short one inside the long one, go around the back of the ear and insert the earplugs into the ear holes, which can also play a fixed role.

Let’s talk about how to wear a single earphone: There are generally three types of single earphones. The earhook is integrated with the earphone. You can directly wear the earhook behind the ear. If the earphones and earhook are separated, you can put one end (circle) of the earhook into the earphone plug, and wear the other end of the earhook against the back. Headphones can be stuck on the head to fix them, and then the headphones can be inserted into the ears.

Question 8: What is the use of Bluetooth? Bluetooth can be used to transfer files, music, pictures, videos, and files across platforms across mobile devices. The most important thing is that it is free and does not require traffic. The new Bluetooth 4.0 allows faster transmission. Can be connected to Bluetooth headsets, smart watches, and monitors.
