1. First, open the "Settings" interface, turn on the Bluetooth of two mobile phones, search and scan nearby Bluetooth devices in the Bluetooth interface, click the Bluetooth you want to connect and pair.

2. After the other mobile phone agrees to pair, turn on the mobile phone music, select the music song to be transmitted, click "Send" in the lower left corner, click "Bluetooth transmission", and select the Bluetooth name of the pair.

In the process of Bluetooth transmission of music and songs by two mobile phones, two mobile phones should be used for operation confirmation, because each step of operation, the other mobile phone will generally receive a request to receive files, and the next operation can only be carried out after receiving the confirmation.

It should be noted that Apple's IOS phone can't use Bluetooth to send songs to the other phone. Genuine Apple Bluetooth only supports Bluetooth device connection and network connection, and does not support any data transmission function.

(The above methods and situations are applicable to mobile phones of Huawei, vivo, Xiaomi and other brands. )
