Sim800l Proteus Library -

void setup() Serial.begin(9600); // For debugging on Serial Monitor sim800.begin(9600); // SIM800L default baud rate

This is where shines. Proteus is a powerful electronic design automation (EDA) software known for its excellent microcontroller simulation capabilities. But to simulate a SIM800L within Proteus, you need a third-party SIM800L Proteus Library . sim800l proteus library

// Send AT command to check communication sim800.println("AT"); delay(1000); void setup() Serial

// Set SMS to text mode sim800.println("AT+CMGF=1"); delay(1000); void setup() Serial.begin(9600)

Serial.println("Starting SIM800L Simulation..."); delay(2000);

// Forward user input to SIM800L (optional) while(Serial.available()) sim800.write(Serial.read());
