With the development of science and technology, in the current Bluetooth function, it is no longer used for Bluetooth to transfer files. The role of Bluetooth is only to transmit sound. The Bluetooth file transfer function has been replaced by APP.

Wifi, Bluetooth, wifi-display (airplay, Miracast, DLNA) are all different functions. The effects are different.

Many buyers often misunderstand the function of Bluetooth. For example: the following 3 types are different functions.
