2. Click agree to install, and the program will start running. Wait a moment, and the system will prompt that no Bluetooth device is detected. At this time, insert the Bluetooth adapter (be sure to wait for the prompt), and the system will automatically recognize it and continue the installation until the installation is completed.
3. After the installation is completed, right-click the desktop computer icon to manage it, and check whether the device is normal in the device manager. Generally, there are two items after installation, as shown below; Secondly, double-click the service and the service opened in the application, and you can see that these two services must be started. After all the above two tests are completed, you can start to experience the Bluetooth service.
4. Double-click the Bluetooth icon in the lower right corner to open the dialog box for adding devices. Click Add Device to search for Bluetooth headsets, select Next, and then wait for the Bluetooth service to install automatically. (If you can't find the headset, it is generally related to the headset not being set to the pairing state. You can turn off the headset, then press and hold the headset switch for about 8 seconds, then release it until the headset indicator flashes quickly or alternately, and then search again. )
5. When all services are installed, a control dialog box will pop up. If it doesn't pop up, you can double-click or right-click the control on the searched headset icon and click Connect.
7. If there is no sound after connection, you can right-click the playback device on the sound icon in the lower right corner, select the headset with Bluetooth audio, set it as the default value, and click OK.
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.
