PART1 What is Bluetooth

Before we dig deeper into this technology, we should have some basic knowledge of it. Why Bluetooth? In fact, this name came from the 10th century Danish King Harald Bluetooth, who unified the current Norwegian, Swedish and Danish with his eloquence.

And this technology will be defined to allow for coordination between different industrial sectors, maintaining good communication between various systems such as work between mobile phones and the automotive industry.

How Does Bluetooth Work

Now, Bluetooth mainly refers to a wireless technology which supports short-range communication (mainly within 10m) of the device. It can exchange information between many devices including mobile phones, PC and peripherals.

The use of this technology can greatly improve the communication between mobile communication terminal devices such as handheld computers, PC and mobile phones. It is also possible to simplify the communication between devices and the Internet, thereby making data transmission more rapid and efficient.

PART2 How can I Know Whether There is a Bluetooth Feature on My Phone

To find Bluetooth, go to the settings of the phone and you can see the option of turning on or off the Bluetooth. Tap the switch to turn it on. If it is already on, you can ignore it. The setup interface may vary depending on the phones.

PART3 How to Pair Your Phone with a Bluetooth Device

First, you should turn on the Bluetooth as we have mentioned above, and then your phone will automatically search for the nearby device that can be paired with.

Wait for a while to find the device you want to pair and then click on the name of the device so that pairing is completed.

Many high-end smartphones nowadays, such as iPhone 7 and later models, Huawei Mate 20Pro or P30 do not have headphone jack.

When you want to listening music via phones, one way is to use a USB Type-C headset or a patch cord. Another way is to resort to a Bluetooth headset.

Since the phone can not be charged if the Type-C interface is be occupied by earphones, many users choose to buy Bluetooth headsets such as Apple AirPods, which can achieve the same quality as wired headsets.

Since it is easy to use and without trouble of the headphone cable, it may be the first choice to use Bluetooth to listen to music and answer calls when driving.
