I am learning GSM and it's interfacing with MCU. I am trying to understand the OpenCPU environment. Can someone please tell me how can I develop HTTP , HTTPs & MQTT communication. Please share if there is any document or any video. I am trying to develop this application on M66 & ECU200UCNAA module. Which method is more convenient AT command or OpenCPU?
Hi，I suggest you use sdk for development, which is essentially to operate modules through AT commands, but we have encapsulated the interface, and there are many apis for you to use, which is convenient for you to operate better. Besides, you can directly write the functions you want to achieve in the sdk. These three are all examples in the sdk of M66. You can use our example to write the features you need
