Car Bluetooth and mobile phone connection:

1. Open.

Turn on both mobile phone Bluetooth and car Bluetooth (car Bluetooth is usually in the reversing image, just click the Bluetooth icon on the home screen) and make it discoverable.

2. Search.

In the Bluetooth interface of your phone, click "Search Device".

The mobile phone can search for car Bluetooth.

3. Pairing.

Select the car Bluetooth displayed on the phone, click Car Bluetooth--Bluetooth Settings--Pairing; At this time, the phone will pop up a dialog box asking to enter the pairing code, enter the pairing code here (the default is 1234 or 0000 or 1111) and click "Connect" (or "Pair" or "OK", the display will be different on different mobile phones), and click "Pair" on the car Bluetooth interface.

4. Connection.

If the pairing code is entered correctly, "Connected" will be displayed on the car Bluetooth after a while. At this time, you can try to make a call using the car Bluetooth. If successful, you can hear the call tone.

5. Automatic connection.

Select the "Automatic Connection" function in the car Bluetooth settings interface. After that, if both the mobile phone and the car Bluetooth are turned on and the range is within 10 meters, automatic connection will be achieved.

Bluetooth (Bluetooth?): It is a wireless technology standard that enables short-distance data exchange between fixed devices, mobile devices and building personal area networks (UHF in the ISM band of 2.4-2.485GHz radio waves).

Bluetooth technology was originally created by telecommunications giant Ericsson in 1994 as an alternative to RS232 data lines.

Bluetooth can connect multiple devices, overcoming 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 around the world, which are distributed in multiple fields such as telecommunications, computers, networks, and consumer electronics.

The IEEE lists Bluetooth technology as IEEE 802.15.1, but this standard is no longer maintained.

The Bluetooth SIG is responsible for overseeing the development of Bluetooth specifications, managing certification projects, and safeguarding trademark rights.

Manufacturers' devices must comply with Bluetooth SIG standards before they can be marketed as "Bluetooth devices."

Bluetooth technology has a proprietary network that is distributed to devices that meet the standards.

The word "Bluetooth" is an Anglicized version of the Scandinavian Bl?tand / Bl?tann (Old Norse blát?nn), which is ten years old. The nickname of Harald Bluetooth, a king in the 19th century who unified the conflicting Danish tribes into a kingdom. According to legend, he also introduced Christianity.

The idea of ??naming Bluetooth after this was originally proposed by Jim Kardach in 1997. Kardach developed a system that allowed mobile phones to communicate with computers.

His inspiration came from The Long Ships, a historical novel about the Vikings and King Harald Bluetooth written by Frans G. Bengtsson that he was reading at the time, which meant that Bluetooth would also unify the communication protocol into Global standard.
