bluetooth module for smart home wireless earbuds kids

With the development of science and technology and the improvement of people's living standards, people pay more and more attention to the comfort, safety and convenience of their living environment. The smart home system that has emerged in recent years meets people's needs. It effectively builds a home information network in the home environment, combines various home appliances into an organic whole, and performs centralized or remote intelligent control and control of home appliances. management and the ability to communicate with the outside world. As an open global specification for wireless data and voice communication, Bluetooth technology can provide a low-power, short-range wireless air interface to realize wireless communication between various fixed and mobile devices. Bluetooth technology is widely used in various fields such as mobile communication, wireless data acquisition, wireless remote control and telemetry, computer network and automatic control. www.bjbjaudio.com

Using the designed bluetooth software and hardware interface, this paper develops a smart home control system based on bluetooth module. In this system, the host computer controls the bluetooth adapter through USB, and the control instructions sent by it are received by the bluetooth module on the lower computer side and then transmitted to One-chip computer, and wrote a basic bluetooth and analog home appliance control program on the one-chip computer side, thus realizing the wireless control function of PC and analog home appliances. The bluetooth software and hardware interface scheme and data transmission module provided in this paper can not only be used to further develop the bluetooth high-level protocol, but also can be applied to various wireless occasions as a general interface function and module. www.bjbjaudio.com    <a style="opacity:0.0;color:#ffffff">wireless earbuds kids</a>           <a style="opacity:0.0;color:#ffffff">wireless earbuds kids</a>

Bluetooth (Bluetooth) is a wireless network transmission technology, originally used to replace infrared. Compared with infrared technology, Bluetooth can transmit data without alignment, and the transmission distance is less than 10 meters (the transmission distance of infrared is within a few meters). With the help of signal amplifiers, the communication distance can even reach about 100 meters. Bluetooth technology is very suitable for sharing data between digital devices with low power consumption, such as mobile phones, classroom computers, etc. The widely used mature versions of the Bluetooth specification are 11, 20, 3.0, and 40, with a bandwidth of about 1M-24Mbps (the bandwidth of the USB11 interface is 12Mbps,
The bandwidth of USB20 connection is 480Mbps, the bandwidth of LAN is 10Mbps/100Mbps/1000Mbps, and the bandwidth of FireWire IEEE1394 is 400Mbps. Therefore, Bluetooth is very suitable for transferring small files (pictures below 10MB, ringtones, e-books, documents, etc.), with both convenience and speed. The latest version is 2.1+EDR version. www.bjbjaudio.com
