What is a Bluetooth adapter and what can it be used for?

The so-called Bluetooth technology is actually a short-distance wireless communication technology. The use of "Bluetooth" technology can effectively simplify the connection between mobile communication terminal equipment such as handheld computers, notebook computers, and mobile phones. It can also successfully simplify the communication between the above devices and the Internet, thereby making the data transmission between these modern communication devices and the Internet faster and more efficient, and broadening the path for wireless communication. To put it more simply, Bluetooth technology enables some modern mobile communication devices and computer devices that are easily portable to be connected to the Internet without the use of cables, and can access the Internet wirelessly. Its practical application scope can also be expanded to various home appliances and consumer electronics. Products and information appliances such as cars form a huge wireless communication network.

Application scope of Bluetooth adapter:

1. File transfer: files can be transferred across different software platforms. More and more mobile phones not only have color displays and polyphonic ringtones, but also Go online and download ringtones, pictures and mini-games to play by yourself. However, downloading over mobile networks offers limited selection, slower speeds, and higher costs. In fact, these problems can be solved by simply using a computer to access the Internet. There are many websites that provide various download resources for mobile phones. You only need to download them to your computer and then transfer them to your mobile phone. If you have a Bluetooth mobile phone, after making some settings, if you want to change pictures, add ringtones or mini-games to your phone in the future, you don’t need to start any program, just a few clicks of the mouse, and your phone’s ringtones and pictures will be instantly refreshing!

2. Data synchronization: supports information synchronization between different operating platforms (such as data synchronization between a handheld computer and a computer, data synchronization between a mobile phone and a computer). The address book on the mobile phone and computer can be said to be a communication A reminder that everyone relies on in life. However, it is quite troublesome to keep both address books with up-to-date information at the same time. The stupidest way is to look at one address book and enter it into another address book yourself. Although some transfer line programs can transfer mobile phone address books to a computer for saving and editing, they cannot be synchronized with Outlook address books.

However, Bluetooth phones can make synchronizing your address book easier. Among them, many Bluetooth mobile phones launched by NOKIA and Sony Ericsson can use Bluetooth and included software to synchronize the phone's address book with the contacts in Outlook, so that your address book can always keep the latest data. Similarly, if your PDA has Bluetooth function, you can also use Bluetooth management software and PDA synchronization software to synchronize your computer and your Bluetooth PDA without the need for a PDA synchronization cradle. What can be done through a sync cable can also be done wirelessly through Bluetooth. Generally, digital cameras also use CF cards. If Bluetooth is not used, the photos taken can be transferred to the PC through a CF card reader in a wired manner. If you have a Bluetooth adapter, insert the CF card into your Bluetooth PDA. , and then use Bluetooth synchronization to connect to the PC, and then read it directly in "Mobile Devices" of "My Computer".

3. Dial-up Networking: Dial up to a modem to connect to the Internet. Computers access the Internet wirelessly through mobile phones. The traditional method is through data cables or infrared rays, both of which have shortcomings. The length of the data cable is limited. If you use a laptop to access the Internet, you may have nowhere to place your mobile phone in a place with limited space. Infrared Internet access requires that the infrared ports of the mobile phone and the computer be aligned in a straight line, which is not convenient. Bluetooth allows computers and mobile phones to be connected without this trouble. You can put your phone in your pocket or bag without deliberately finding the best position. As long as the distance is within ten meters, wireless Internet access can be achieved from any angle.

4. Voice transmission: This is the service of Bluetooth audio gateway. If you have a Bluetooth headset, you can use it as a wireless headset for your computer. Even if your computer does not have a sound card, microphone and speakers, you can listen to music through the Bluetooth headset and conduct voice chats through MSN, QQ, etc.

5. Set up a Bluetooth network: At present, most families have more than two computers, and many people have a desktop computer and a laptop. How can I enable both computers to access the Internet? What most people do is to pull a network cable or use a wireless network.

The project of pulling network cables is huge, and the computer cannot move freely away from the network hole. Although the wireless network is fast and convenient, the price of wireless base stations and network cards is relatively high. In fact, in addition to these two methods, we can also use Bluetooth to allow two computers to share the network connection without pulling a cable. As long as you have a computer with Internet access, you can use a Bluetooth connection (Bluetooth adapters are installed on both computers) to share the network connection with another Bluetooth computer, so that both computers can access the Internet!

6. Use a Bluetooth phone to control your computer: This is cool! As long as you install and set up PC Control and other similar remote control software on your computer, even if you are lying in bed and want to listen to some MP3 music on your computer, as long as you have a Bluetooth phone, you can control your computer! Moreover, you can also use the built-in PowerPoint support function as a slide controller when making slideshows in the company. You don’t have to sit in front of the computer. You can easily control the computer with just a click of your mobile phone, which is very convenient.

7. Bluetooth turns your computer into a headset for your mobile phone: If you have a Bluetooth phone, I believe that the Bluetooth headset must be one of your most wanted Bluetooth accessories. But Bluetooth headsets are not cheap. If you have a limited budget and cannot own a real Bluetooth headset, you might as well let your computer cosplay and turn your Bluetooth computer into a headset! Although it is impossible to hang a Bluetooth computer on your ear, with a little setting, your computer can automatically answer the computer like a Bluetooth hands-free. When you talk on the phone, speak into the microphone, and the other party's voice will be played from the computer speaker. This function requires that your Bluetooth phone must support Bluetooth audio. If it does not have it, such as NOKIA 7650, there is no way to implement it.

8. Send text messages on your computer via Bluetooth: If you have a Bluetooth phone, you don’t have to edit text messages on your phone. You can directly type the text messages in the text messaging software on your computer. It can be sent out, how convenient! This function is already included in many mobile phone management software, or there are similar text messaging software such as SMS Sender.

9. Let the computer use a Bluetooth mouse and Bluetooth keyboard: If you use a Bluetooth adapter on your computer, your computer becomes a Bluetooth computer, and you can use a Bluetooth mouse and Bluetooth keyboard as your human interface equipment, truly getting rid of the shackles of cables. Even if your computer desktop is overcrowded with files and you have to put your mouse or keyboard on another free desk, you can still use your Bluetooth mouse or keyboard freely and freely.

Fax service: If you own a Bluetooth mobile phone, you only need to go to the data fax service opened by China Mobile, install fax software such as WINFAX on your computer, and then designate the data machine as You can use the mobile phone port to send faxes wirelessly via Bluetooth from your computer.

12. Let PPC and PC enjoy the Internet in a non-synchronized manner: through Bluetooth, let PPC enjoy PC broadband network and hard disk resource space and other equipment, so that within a certain range To solve the problem of PPC wireless Internet access and data storage, the implementation of this function also utilizes the Bluetooth network access service. PDAs with similar functions include PDA Compaq iPaq 1940, 3970, 2210, etc.
