What is the Bluetooth function of tablets?

Bluetooth is a radio technology that supports short-distance communication of devices (generally within 10m). It can conduct wireless information exchange between many devices including mobile phones, PDAs, wireless headsets, laptops, related peripherals, etc. The use of "Bluetooth" technology can effectively simplify the communication between mobile communication terminal devices, and can also successfully simplify the communication between the device and the Internet, so that data transmission becomes faster and more efficient, broadening the path for wireless communication.

Bluetooth adopts a decentralized network structure and fast frequency hopping and short packet technology, supports point-to-point and point-to-multipoint communication, and works on the globally accepted 2.4GHz ISM ( That is, industrial, scientific, medical) frequency bands. Its data rate is 1Mbps. The time division duplex transmission scheme is used to achieve full-duplex transmission.
