how i can't solve this problem?
#include <SoftwareSerial.h>
SoftwareSerial SIM800L(2, 3); // RX | TX
// Connect the SIM800L TX to Arduino pin 2 RX.
// Connect the SIM800L RX to Arduino pin 3 TX.
char c = ' ';
void setup()
{
// start th serial communication with the host computer
Serial.begin(9600);
while(!Serial);
Serial.println("Arduino with SIM800L is ready");
// start communication with the SIM800L in 9600
SIM800L.begin(9600);
Serial.println("SIM800L started at 9600");
delay(1000);
Serial.println("Setup Complete! SIM800L is Ready!");
}
void loop()
{
// Keep reading from SIM800 and send to Arduino Serial Monitor
if (SIM800L.available())
{ c = SIM800L.read();
Serial.write(c);}
// Keep reading from Arduino Serial Monitor and send to SIM800L
if (Serial.available())
{ c = Serial.read();
SIM800L.write(c);
}
}
