How to send a short message to another device via Bluetooth?

There are two ways to turn on Bluetooth. One is to turn on Bluetooth through shortcuts, such as the Bluetooth switch on the desktop and the drop-down menu in the status bar, and the other is to select the Bluetooth option in the menu settings.

Set up Bluetooth and pair Bluetooth. Press the menu button on the Bluetooth interface to see three menus: Rename, Timeout Detection, and Display Received Files. Rename can name the mobile phone as you like, which is easy to identify.

For example, "my mobile phone" and "an old sow", click on the name of the mobile phone to make your mobile phone in a detectable state. At this point, another mobile phone that needs to be paired has also been set up and can be detected in available devices.

After detecting the phone to be paired, click Device Name-Select Pairing.

At this time, the Bluetooth pairing request interface will be displayed on both devices. After checking the key, select "Pairing" to pair the phone, and then use Bluetooth to transfer the file again without matching again.

Use Bluetooth to transfer files.

After pairing, you can transfer any readable files between the two phones, such as photos, music, videos, APK packages, etc.

Bluetooth:

Bluetooth (Bluetooth? ): is a wireless technical standard, which can realize short-distance data exchange between fixed equipment, mobile equipment and personal area network of buildings (using UHF radio waves in ISM band of 2.4 ~ 2.485 GHz). Bluetooth technology was first invented by telecom giant Ericsson in 1994 as a substitute for RS232 data line. Bluetooth can connect multiple devices, which overcomes the problem of data synchronization.

Today, Bluetooth is managed by the Bluetooth Special Interest Group (SIG). The Bluetooth Technology Alliance has more than 25,000 member companies in the world, which are distributed in many fields such as telecommunications, computers, networks and consumer electronics. IEEE lists Bluetooth technology as IEEE 802. 15. 1, but this standard is no longer maintained. Bluetooth Technology Alliance is responsible for supervising the development of Bluetooth profile, managing certification projects and maintaining trademark rights. The manufacturer's equipment must meet the standards of Bluetooth Technology Alliance before it can enter the market in the name of "Bluetooth equipment". Bluetooth technology has a set of patented networks that can be distributed to devices that meet the standards.
