1. Maybe the Bluetooth headset does not have the pairing function turned on. Solution: Double-click the button on the Bluetooth headset to open the pairing function.
2. The mobile phone may not be turned on for testing. Solution: Just turn on the Bluetooth detection of the mobile phone.
3. Restart the phone. Maybe the CPU of the mobile phone is too high to connect.
4. There is something wrong with the hardware equipment, whether it is the Bluetooth headset or the Bluetooth function of the mobile phone, it will lead to the phenomenon that Bluetooth cannot be connected.
5. If the above methods can't solve the problem, it may be that the mobile phone is incompatible. At this time, you can only go to the merchant to exchange goods.
Bluetooth technology is an open global specification for wireless data and voice communication. It is a special short-distance wireless technology connection based on low-cost short-distance wireless connection, which establishes a communication environment for fixed and mobile devices.
Bluetooth enables some portable mobile devices and computer devices to connect to the Internet without cables, and can access the Internet wirelessly.
The characteristics of Bluetooth technology and Bluetooth products mainly include:
1 Bluetooth technology is suitable for a variety of devices, and computers and telecommunications can communicate with each other through wireless networks without cables.
The working frequency band of Bluetooth technology is universal all over the world, which is suitable for users all over the world to use without borders, and solves the national border obstacle of cellular phones. Bluetooth technology products are very useful. With a Bluetooth device, you can search for another Bluetooth technology product and quickly establish a connection between the two devices. With the help of control software, data can be transmitted automatically.
Bluetooth technology has strong security and anti-interference ability. Because Bluetooth technology has frequency hopping function, ISM frequency band is effectively prevented from encountering interference sources. Bluetooth technology has good compatibility. Bluetooth technology has been able to develop into a technology independent of the operating system, achieving good compatibility in various operating systems.
4 Short transmission distance: At present, the main working range of Bluetooth technology is about 10 meter. After increasing RF power, Bluetooth technology can work in the range of 100 meters. In this way, the working quality and efficiency of Bluetooth can be guaranteed and the transmission speed of Bluetooth can be improved.
In addition, the interference between Bluetooth technology and other electronic products can be effectively reduced during the connection process, thus ensuring the normal operation of Bluetooth technology. Bluetooth technology not only has high communication quality and efficiency, but also has the characteristics of high communication security.
5 Frequency hopping spread spectrum technology spread spectrum: In practical application, Bluetooth technology can divide and convert the original frequency points. If some Bluetooth technologies with faster frequency hopping are adopted, the main unit in the whole Bluetooth system will automatically switch frequency hopping, so it will randomly frequency hop. Because Bluetooth technology itself has high security and anti-interference ability, it can run with high quality in practical application.
