ABSTRACT
MCU is connected to the wireless router through the serial to Wi-Fi module, to achieve the communication with other devices connected to the route. For security considerations, modules only receive data transmitted from the target set machine’s IP and target set machine’s port by default, and only send data to the configured destination. Users can easily and immediately control the parameter settings of the modules, to modify the delivery destination. Users can also customize
1 INTRODUCTION
Data transmission can be simply divided into two categories: cable (including the erection of cable, cable, or leased telecommunication line) and wireless (divided into build special-purpose wireless data transmission system or use of CDPD, GSM, CDMA, and other public network information platforms). In some industrial control environments, there are certain limitations in cable communication, and the use of wireless communication will not be constrained by these ways.
