Is the Bluetooth function free, and how does the Bluetooth function work?

Bluetooth is a protocol for transmitting data between two or more Bluetooth devices, and it is free for us to use, but the manufacture of Bluetooth devices requires the payment of Bluetooth patent royalties to the Bluetooth standards organization.

Remember.

Will you use the Bluetooth function in your phone? Teach you the correct use of Bluetooth, and try it after reading! Life Tips, Life Tips, Life Tips, Life Tips.

Bluetooth can be said to be a wireless transmission method, its function is like the infrared remote control of the TV, the difference is that it can transmit data.

If a mobile phone wants to transfer data to the computer, the first thing that the computer can detect is the Bluetooth function, and an adapter is required. Mobile phones are different.,The specific operation should be on your mobile phone manual.。。 It's simple, just like the remote control!

Between mobile phones, mobile phones and computers can be connected to each other through Bluetooth**, etc., instead of having to have a data cable. It is a radio technology that supports short-range communication between devices (generally within 10 meters).

The mobile phone will be in the "Settings" - Connection (different mobile phones may be in different places, find it yourself), after finding it, you must first turn on the Bluetooth, and then select "Search for paired devices" to find the device that needs to be paired to connect. The first connection will require a password, this password is entered by the initiator of the pairing, you can enter it casually, the password of the recipient of the pairing is entered by the initiator, and the file can be transferred after the pairing is successful. The shortcut menu will come out when the smartphone clicks and holds the required file to be transmitted, which has "send" - via Bluetooth", so that it can be directly transmitted to the device that has been paired successfully without turning on Bluetooth, remember to turn off Bluetooth after use.

My phone is like this, there may be differences between different models, you can see for yourself)

Apple phones can't be paired with a series of mobile phones such as Nokia, Samsung, etc.

Hope it will help you.

Short-distance file and audio transmission and reception. Enable Bluetooth devices, search for devices, pair, and send or read data to each other after success. Two or more devices transfer files to each other within a distance of ten meters.

Here's how to use Bluetooth:

The mobile phone must first turn on "Bluetooth", and then the mobile phone will automatically enter the Bluetooth search interface, and the Bluetooth device to be paired should also be turned on or enter the pairing and search interface, select the Bluetooth device to be paired, and select "Confirm" (or enter the password) according to the prompts to pair successfully!

Note: Whether you want to enter the password, by the Bluetooth device to be paired to decide, if the paired Bluetooth device has an input button, then the pairing of both parties can enter the same password, if you want to pair the Bluetooth device without entering the button, then check the Bluetooth device's manual, according to the manual, enter the fixed password of the Bluetooth device on the mobile phone! ）。

Problem description: Many mobile phones and *** are Bluetooth shouting technology, so what are the benefits of having Bluetooth.

Analysis: Bluetooth wireless technology is a low-cost, low-power, short-range radio frequency wireless technology for mobile devices and WAN access points. At present, more than 2,000 companies support Bluetooth technology.

This fact illustrates that Bluetooth is fast becoming one of the widely accepted low-cost wireless technologies for personal area networks (PANs). Bluetooth technology enables the transmission of signals between broadband access devices, PCs, information appliances and other devices over short distances.

When it was first introduced, Bluetooth technology was very slow, but as the technology evolves and more and more manufacturers in the fields of digital consumer electronics, mobile phones and automotive electronics produce Bluetooth-enabled products, it is bound to arouse more consumer interest in this technology and gradually understand the benefits of Bluetooth technology in the era of wireless communication.

Bluetooth technology is a short-range wireless connection technology used to replace cables or wires used in portable or stationary electronic devices. The device uses the world's most accessible, license-free frequency bands for real-time data and voice transmission, with a transmission rate of up to 10 Mbits, supporting up to 3 voice channels and up to data transfer rates. That is to say, in the office, home and on the go, there is no need to lay special cables and connectors between any electronic devices, and a one-point to multi-point connection can be formed through the Bluetooth remote control device, that is, a "micro-grid" is formed around the device, and any Bluetooth transceiver in the network can communicate with the device.

Bluetooth"Technology.

Bluetooth"It is a strange name, an inconspicuous little thing, but it may play a leading role in the future development of information technology. With the development of information technology and digital technology, especially the growth of the need for the Internet and multi-communication, people's demand for communication is increasingly concentrated in the field of broadband network and wireless communication. "Bluetooth", a wireless communication technology for short distances proposed by Ericsson, Nokia, IBM, Intel and Toshiba, has become one of the hot spots in the industry.

Bluetooth is an open technical standard for short-range wireless communication. The wolf's teeth are jagged, but they bite together. Figuratively speaking, "Bluetooth" is a technology that can tightly bind unrelated electronic products such as headphones, laptops, refrigerators, and televisions.

Bluetooth is a short-range wireless data transmission technology.

All have Bluetooth capabilities? Bluetooth technology, named after the tenth-century Danish king Whisper Potato Pure Harold"Bluetooth"And naming is currently a hot topic for wireless developers.

Bluetooth technology makes low-bandwidth wireless connectivity simple and easy, making it easy to incorporate into your daily routine. A simple example of the application of Bluetooth technology is updating your phone's directory. Today, you may also need to manually enter everyone's name and number, or launch an app to sync your contact information with a cable or IR link between your computer and your computer.

With Bluetooth technology, these can all be done automatically when they come within range of communicating with the computer, without the need for user intervention. Of course, its features are constantly expanding, including the ability to automatically sync and update calendars, worksheets, notes, emails, and more. This is just one of the many exciting applications of this new technology.

Imagine walking into a store and all the product names are automatically listed on your phone or PDA, and with Bluetooth, it's all possible.

The Bluetooth specification is an open standard that consists of:"Bluetooth Special Interest Group"(SIG) management. Bluetooth SIG is led by five founding companies and four new member companies that joined at the end of 1999 to form the Bluetooth SIG Promoter Group

No, to achieve Bluetooth function, it is necessary to install a stool and a Bluetooth adapter on the computer, with spring cherry blossoms it can carry out Bluetooth communication, some laptops come with, and some do not, most desktop computers do not have their own Bluetooth to change the cluster.

The use of mobile phone Bluetooth is relatively simple, if you have used your own mobile phone and other people's mobile phone Bluetooth transmission songs, perhaps the use of blue will be more clear, first of all, you need to turn on Bluetooth and blue devices, and then search on the mobile phone, and finally the two are paired, and you can use Bluetooth after successful pairing.
