Let customers speak for us

Devices can subscribe to other MQTT client messages, and can publish topic information to the server. Supports subscription of 6 messages and publication of 6 topics, wider range of use and more applicable scenarios. Users can view device-related information through terminal devices or cloud platforms.	After the user has set the HTTP header through AT commands or web page, the module can send data to the HTTP server, or obtain data from the HTTP server
Users send data to servers according to the protocol and can send data to different servers without restarting	Support Modbus TCP And Modbus RTU Interconversion Mode
