Microcontroller or single-board computer (e.g., Arduino, Raspberry Pi)
Power supply (5V, 2A)
Antenna (optional)Software RequirementsSerial communication library (e.g., Serial library in Arduino)
GSM/GPRS library (e.g., SIM800L library in Arduino)Code Examples### Example 1: Sending SMS using ArduinoIn this example, we will use the Sim 800L GSM - GPRS module to send an SMS using an Arduino board.```cpp
#include <SoftwareSerial.h>
#include <SIM800L.h>#define RX_PIN 10
#define TX_PIN 11
#define SMS_CENTER_NUMBER "+1234567890"SIM800L gsm = SIM800L(RX_PIN, TX_PIN);void setup() {
Serial.begin(9600);
gsm.begin(9600);
delay(1000);
gsm.sendCommand("AT"); // Check if the module is working
delay(1000);
}void loop() {
gsm.sendSMS(SMS_CENTER_NUMBER, "Hello from Sim 800L GSM - GPRS module!");
delay(1000);
}
```### Example 2: Making a Voice Call using Raspberry Pi (Python)In this example, we will use the Sim 800L GSM - GPRS module to make a voice call using a Raspberry Pi.```python
import serial
import time# Open the serial connection
ser = serial.Serial('/dev/ttyUSB0', 9600, timeout=1)def make_call(number):
ser.write(b'AT
')
time.sleep(1)
response = ser.readline()
print(response.decode())ser.write(b'ATD' + number.encode() + b';
')
time.sleep(1)
response = ser.readline()
print(response.decode())-number = "+1234567890"
make_call(number)
```Note: Make sure to replace the `RX_PIN`, `TX_PIN`, and `SMS_CENTER_NUMBER` placeholders with the appropriate values for your setup. Additionally, ensure that the Sim 800L GSM - GPRS module is properly configured and connected to your microcontroller or single-board computer.TroubleshootingCheck the power supply and connections to the module.
Verify that the SIM card is properly inserted and activated.
Use the AT command set to troubleshoot and configure the module.
