What is Bluetooth technology?
What is Bluetooth technology? As a low-cost, short-range wireless connection technology standard, Bluetooth is a global wireless technology standard jointly promoted by Ericsson, IBM, Intel, Nokia and Toshiba. It is an openness of wireless data and voice communication. Global norms.
It is based on a low-cost short-range wireless connection that establishes a special connection between the fixed device and the mobile device communication environment. The essence is to establish a common wireless air interface and its open software standards for control software to achieve cable replacement for equipment.
The Bluetooth specification includes two parts, the protocol and the application specification. The protocol defines the working mode of each functional element. The entire Bluetooth protocol architecture is divided into four layers, namely the core protocol layer, the cable replacement protocol layer, the telephone control protocol layer and other protocol layers adopted; the application specification states that in order to achieve A specific application model, the operational coordination mechanism between the layers of the protocol. Typical application specifications are dial-up networking, headsets, LAN access, and file transfers.
