Function Block Diagram
Transparent Transmission Mode
Supports TCP Server, TCP Client, UDP Server, UDP Client
Advanced Functions
MQTT Support
Devices can subscribe to messages from other MQTT clients and publish topic information to the server. Supports subscribing to 6 messages and publishing 6 topics, offering a wider range of uses and more applicable scenarios. Users can view device information through terminal devices or cloud platforms.
HTTP Client
After the user has set the HTTP header via AT commands or webpage, the module can send data to the HTTP server or receive data from the HTTP server
Protocol Transmission
Users send data to servers according to the protocol and can send data to different servers without restarting
Modbus Conversion
Supports mutual conversion mode of Modbus TCP and Modbus RTU
Supports Multiple Wireless Connection Methods
Supports AP mode, STA mode, and AP+STA mode
Features
Supports multiple configuration methods such as host, web browser, and serial port configuration
The built-in webpage allows setting IP address, port number, serial port baud rate, and other parameters through the web interface.
The user can query the current state of the module or set related parameters by sending AT commands
In transparent transmission mode, the serial device can send data to the specified Socket connection; the network data of each Socket is sent to the serial device through the serial port
The Websocket function implements data interaction between the module's webpage and the module's serial port; the Websocket server function allows the module's serial port to interact with the webpage in real-time, replacing previous HTTPGET, POST, and PUT methods for faster response times.
The registration pack is used to identify device information on the server, so the server can recognize the device
Through this Ethernet port, data can be transmitted between WiFi, serial port, and Ethernet port.
