How to use Bluetooth on mobile phone?

If you use a vivo phone, you can go to the phone settings-(other networks and connections/more settings)-and turn on Bluetooth.

Bluetooth is used as follows:

First, the mobile phone should turn on "Bluetooth", then the mobile phone will automatically enter the Bluetooth search interface, and the Bluetooth device to be paired should also turn on or enter the pairing and search interface. Select the Bluetooth device to be paired, and select "OK" (or enter the password) according to the prompt. Pairing is successful!

(Note: Whether to enter the password depends on the Bluetooth device to be paired. If the paired Bluetooth device has an input button, both parties can enter the same password. If the paired Bluetooth device does not have an input button, check the manual of the Bluetooth device and enter the fixed password of the Bluetooth device on the mobile phone according to the manual! )
