Application and improvement of multiplexing protocol in wireless communication

This article introduces the implementation of serial communication link reuse, between the Internet of the Things devices and wireless communication module, and presents a new implementation. Through the pseudo-terminal functions of Linux system, the new method implies a serial communication link multiplexing layer between the Internet of the Things devices and wireless communication module. Compared to Linux module implementation of the traditional serial communication link multiplexing protocol, TS27.010, it will be more flexible and more versatile. At present, this design has been applied to the developped mobile devices in the vehicle successfully.
