There is something wrong with the connection of the earphone

The Bluetooth earphone keeps flashing white light. At this time, there is something wrong with the connection of the earphone. It is suggested to adopt the following two methods to solve the problem: the first method is to press the touch screen of the earphone at the same time and wait for the earphone to automatically restart after being turned off, thus restoring the factory settings; In the second case, two Bluetooth headsets are put into the headset box, and the headset box can be reset and restored to normal after being closed and taken out again.

Precautions for using Bluetooth

First, the wearing direction of headphones and mobile phones should be kept on the same side of the body as far as possible.

second, avoid putting the mobile phone in the bag. Generally speaking, canvas bags will cause less obstacles, while purses or briefcases will cause more obstacles.

3. In case of similar interference, you can delete the Bluetooth device in the mobile phone, turn it off, restart it, and then pair it with the Bluetooth headset again.

fourth, the most important thing to pay attention to when using the Bluetooth headset is the charging time of the built-in battery of the Bluetooth headset. The charging time of the new Bluetooth headset is between 2 and 3 hours, and the charging time of the used one is better between 1 and 2 hours.

Bluetooth_ (bluetooth _) is a wireless technical standard, which can realize short-distance data exchange between fixed equipment, mobile equipment and building personal area network (using UHF radio waves in ISM band of 2.4~2.485GHz). Bluetooth technology was first invented by telecom giant Ericsson in 1994 as an alternative to RS232 data line. Bluetooth can connect multiple devices, which overcomes the problem of data synchronization.

today, bluetooth is managed by BluetoothSpecialInterestGroup (SIG). The Bluetooth Technology Alliance has more than 25, member companies in the world, which are distributed in many fields such as telecommunications, computers, networks, and consumer electronics.

IEEE listed Bluetooth technology as IEEE82.15.1, but now it no longer maintains this standard. Bluetooth Technology Alliance is responsible for supervising the development of bluetooth profile, managing certification projects and safeguarding 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 patent network, which can be distributed to devices that meet the standards.

Bluetooth was originally a king who unified Denmark in the 1th century. He unified Sweden, Finland and Denmark at that time. Naming this new technical standard after him means unifying the fragmented situation. Bluetooth technology uses advanced technologies such as FH (FrequencyHopping) and TDMA (Time Division Muli-Access) to link several digital devices (all kinds of mobile devices, fixed communication devices, computers and their terminal devices, all kinds of digital data systems, such as digital cameras, digital video cameras, and even all kinds of household appliances and automation devices) in a short distance at the cheapest cost. Bluetooth technology will be a unified bridge for the interfaces of various peripheral devices in the network, which eliminates the connection between devices and replaces it with wireless connection.
