To download or transmit data via Bluetooth, you need to perform the following necessary steps: 1. Whether both devices have Bluetooth function (if it is a computer, you also need to install the Bluetooth driver correctly, and you have to go to "Devices and Printers" "Add the Bluetooth device correctly in "");

2. Whether the Bluetooth function is turned on on the device. Use the key combination (usually Fn F5) to switch the Bluetooth switch on the notebook. On the mobile phone, you can usually find it in "Settings--Wireless and Network".

3. Two devices must be successfully connected.

4. The transmission distance should generally not exceed 10 meters, otherwise the transmission will be interrupted.

5. There will be a success prompt if the transmission is successful. Just find the file on the recipient and open it (usually in the "File Management--Local--Internal Storage--Bluetooth" folder).

6. Select the file to be transferred, select "Share" in the menu, then select "Bluetooth", and then follow the prompts. If the operation is correct, there will be a prompt that the transfer is completed successfully.

Bluetooth is a wireless technology standard that enables short-range data exchange between fixed devices, mobile devices and building personal area networks. Bluetooth technology was originally created by telecommunications giant Ericsson in 1994 as an alternative to RS232 data lines. Bluetooth can connect multiple devices, overcoming the problem of data synchronization.

Today Bluetooth is governed by the Bluetooth SIG. The Bluetooth Technology Alliance has more than 25,000 member companies around the world, which are distributed in multiple fields such as telecommunications, computers, networks, and consumer electronics. The Bluetooth SIG oversees the development of Bluetooth specifications, manages certification programs, and protects trademark rights. A manufacturer's device must comply with Bluetooth SIG standards before it can be marketed as a "Bluetooth device." Bluetooth technology has a proprietary network that is distributed to devices that comply with the standard.
