SIM800 modem supports AT commands over serial communication. For connecting it with the computer, it must be interfaced with a controller as it does have any controller on itself. The Arduino UNO is used in this configuration setup. The Arduino UNO acts as USB-to-serial converter. It...
打开串口监视器,设置波特率为9600。 在串口监视器中输入AT指令,检查GSM模块是否正常工作。如果GSM模块正常工作,将返回"OK"作为响应。 使用以下代码发送短信:void sendSMS(String phoneNumber, String message) { gsmSerial.println("AT+CMGF=1"); // 设置短信模式为文本模式 delay(1000); gsmSerial.println...

This library opens a TCP (or SSL) connection to a server. In theOSI model, that'slayer 4(or 5 for SSL). HTTP (GET/POST), MQTT, and most of the other functions you probably want to use live up atlayer 7. This means that you need to either manually code the top layer or use ...
