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 The Bluetooth file transfer function has been replaced by APP.

For smartphones that support screen mirroring, there are options similar to this in the “Settings” or “More Functions” options of the smartphone, for example: “Screen mirroing”, “Wifi-display”, “multi-screen”, “screen projection”, “play to”, “media output”, etc.
