Bluetooth technology was first created by Ericsson in 1994 as an alternative to RS232 data line. Bluetooth can connect multiple devices to overcome the problem of data synchronization. As Bluetooth devices such as Bluetooth headset, Bluetooth mouse and Bluetooth speaker gradually fill our life, Bluetooth is no longer simply an alternative to data line.


Today, Bluetooth is managed by the Bluetooth special interest group (SIG). Bluetooth technology alliance has more than 25000 member companies in the world, which are distributed in the fields of telecommunications, computer, network, and consumer electronics.

Bluetooth has developed from Bluetooth 1.0 to Bluetooth 5.1. It has a great improvement in performance and usability. What are the upgrade aspects of the latest Bluetooth 5.1 compared with the old version of Bluetooth? As a small version of Bluetooth 5.0, we should first know what the Bluetooth 5.0 has improved. Bluetooth 5.0 is mainly improved as compared with Bluetooth 4.2le:


High speed transmission: its transmission rate reaches 24mbps, twice that of Bluetooth 4.2le


Transmission distance: the effective transmission distance is four times that of the previous version. In theory, the effective working distance between Bluetooth transmitting and receiving devices can reach 300 meters.


Precise positioning: combined with WiFi, indoor positioning with accuracy less than 1 meter can be realized


Ultra low power consumption: Bluetooth 5.0 will greatly reduce the power consumption of Bluetooth, so that people no longer have to worry about short standby time in the process of using Bluetooth.

It can be seen that the Bluetooth 4.2le of Bluetooth 5.0 has been greatly improved. On January 28 this year, the Bluetooth Technology Alliance (SIG) announced the latest Bluetooth standard - Bluetooth 5.1. Compared with 5.0, the latest version of Bluetooth adds direction finding function and centimeter level positioning service, which makes indoor positioning more accurate, and can also accurately locate small objects to avoid the loss of items.


With the continuous improvement and upgrading of Bluetooth functions, the types of terminal devices equipped with Bluetooth will be more and more abundant, and our life will be more and more convenient because of Bluetooth.
