  • Page 12: Function Description

    5. Function Description The working mode of this module is divided into three levels: working role; transmission mode; service category. From the role of the WiFi layer, it can be divided into Access Point, commonly known as AP access point, Station, commonly known as station, and WiFI-Direct, also known as P2P or WiFi direct connection;...

    For example: AA FE 55 00 00 03 11 22 33 In protocol mode, the 3-byte data received from Socket0, the content is: 0x11 0x22 0x33 Use the command AT+MODE=x.2,x to set the second bit to configure the module to work in the protocol transmission mode.

  • Page 14: Service Mode

    You don't need to care about the complex HTTP protocol layer. For details, see Chapter 6 HTTP Client Configuration Tutorial. 5.3.6 WebSocket The traditional HTTP transmission protocol is based on access and response. In this way, the server is always passive and Copyright ©2012–2021，Chengdu Ebyte Electronic Technology Co.,Ltd.

  • Page 15: Parameter Configuration

    The application of the WebSocket function allows the E103-W03 module to pass the serial port. Real-time interaction with the web page saves the GET and POST request process initiated by the HTTP client during multiple interactions, improves the response speed, and the module side can actively push data to the web page.

  • Page 16: Low Power Consumption

    3. Only the TCP server, TCP client, UDP, MQTT, WebSocket and P2P modes support the Modbus protocol, but the HTTP client does not. The reason is that because the HTTP client is a short-connection communication method, the server cannot actively initiate data exchange.
