Multi-transmit and receive solution based on 433MHz wireless serial port Introduce
Background of wireless development: With the rapid development of science and technology, smart homes, smart agriculture, and smart cities are springing up. And the development of these industries is inseparable from the application of wireless. The traditional wired connection is not only costly, but also includes wiring installation and maintenance. serial module And the mobility is also very poor, can not meet the development needs of the intelligent industry, so wireless applications have entered the stage of the development of the intelligent industry. In the use of wireless transmission, the wireless use of the 433M band is more widespread. The main reasons are: 433M is the ISM band 433M long transmission distance 433M strong anti-interference ability 433M should be relatively balanced in terms of transmission speed and diffraction performance. In wireless applications, traditional point-to-point transceivers can no longer meet the application requ
