First, make sure the computer has a Bluetooth module. If so, please check whether widcomm is installed. Right-click my computer, select Manage, and then click Device Manager to check whether the driver is installed on the correct page.
Turning on notebook Bluetooth generally involves two Bluetooth switches, one is the computer Bluetooth switch and the other is the software Bluetooth switch. The computer Bluetooth switch is generally on the side of the computer, which is similar to a small slider. Look closely and you will find it.
Turn on the computer Bluetooth, and then turn on the Bluetooth. Go to Start-Control Panel-Hardware and Sound-Devices and Printers. You can see the Bluetooth logo inside, just click on it (you can also use the combination key, usually Fn+F5, which is different for different computers. Please refer to the instruction manual for details).
Bluetooth (Bluetooth? ): is a wireless technical standard, which can realize short-distance data exchange between fixed equipment, mobile equipment and personal area network of buildings (using UHF radio waves in ISM band of 2.4-2.485 GHz). Bluetooth technology was first invented by telecom giant Ericsson in 1994 as a substitute for RS232 data line. Bluetooth can connect multiple devices, which overcomes the problem of data synchronization.
Today, Bluetooth is managed by the Bluetooth Special Interest Group (SIG). The Bluetooth Technology Alliance has more than 25,000 member companies in the world, which are distributed in many fields such as telecommunications, computers, networks and consumer electronics. IEEE lists Bluetooth technology as IEEE 802. 15. 1, but this standard is no longer maintained. Bluetooth Technology Alliance is responsible for supervising the development of Bluetooth profile, managing certification projects and maintaining trademark rights. The manufacturer's equipment must meet the standards of Bluetooth Technology Alliance before it can enter the market in the name of "Bluetooth equipment". Bluetooth technology has a set of patented networks that can be distributed to devices that meet the standards.
