#include <SoftwareSerial.h>SoftwareSerial sim7670c(2, 3); // RX, TXvoid setup() {
sim7670c.begin(9600);
Serial.begin(9600);// Initialize the module
sim7670c.println("AT");
delay(1000);
sim7670c.println("AT+CFUN=1");
delay(1000);// Set SMS text mode
sim7670c.println("AT+CMGF=1");
delay(1000);
}void loop() {
// Send SMS
sim7670c.println("AT+CMGS=""+1234567890""");
delay(1000);
sim7670c.println("Hello, this is a test message from SIM7670C.");
delay(1000);
sim7670c.println((char)26); // Send the SMSdelay(10000); // Wait 10 seconds before sending the next SMS
}
```### Example 2: Establishing a 4G LTE Connection with the SIM7670C module using a Raspberry PiThis example demonstrates how to establish a 4G LTE connection using the SIM7670C module with a Raspberry Pi. The code uses the `pppd` dialer to establish a PPP connection.```python
import os
import time# Set the APN, username, and password
apn = "your_apn"
username = "your_username"
password = "your_password"# Set the serial interface
ser = "/dev/ttyUSB0"# Initialize the module
os.system("sudo stty -F " + ser + " 115200")
time.sleep(1)
os.system("sudo echo 'AT' > " + ser)
time.sleep(1)
os.system("sudo echo 'AT+CFUN=1' > " + ser)
time.sleep(1)# Establish the PPP connection
os.system("sudo pppd call gprs APN=""" + apn + """ USER=""" + username + """ PASSWORD=""" + password + """ connect '/usr/sbin/chat -v -f /etc/ppp/chat'")print("Connected to 4G LTE network!")
```Please note that these examples are for illustration purposes only and may require modifications to work with your specific IoT project. Additionally, ensure that you have a valid SIM card and compatible network coverage for the module to function correctly.
