Hey guys,
I have been trying to send emails with the GSM SIM800l but it doesn't work properly.
It is sending an email but instead of setting the body of the email to the specified text,
it sends the whole command set as the email body.
I have used the following document for commands.
Here is My code
#include <SoftwareSerial.h>
#define SERIAL_BUFFER_SIZE 512
SoftwareSerial sim(10, 11);
String sender = "\"user@email.com\"";
String pass = "\"*******\"";
String reciever = "\"reciever@gmail.com\"";
String user1 = "\"user\"";
String user2 = "\"reciever\"";
String subject = "\"Email subject\"";
String body = "\"This is the email body\"";
String server = "\"mail.email.com\",";
int port = 587;
String apn = "ISP apn name";
String _output;
void setup()
{
delay(7000); //delay for 7 seconds to make sure the modules get the signal
Serial.begin(57600);
Serial.println("System Started...");
sim.begin(57600);
delay(1000);
sim.println("ATE1");
sim.println("AT+SAPBR=3,1,\"contype\",\"GPRS\""); // configure bearer profile 1
sim.println("AT+SAPBR=3,1,\"APN\"," + apn); //configure Access point name
sim.println("AT+SAPBR=3,1,\"USER\",\"apn user name\""); //
sim.println("AT+SAPBR=3,1,\"PWD\",\"apn password\"");;
}
void loop()
{
dataOn();
delay(100);
sendEmail();
_readSerial();
delay(120000);
dataOff();
}
void dataOn()
{
sim.println("AT+SAPBR=1,1"); // open GPRS context
}
void dataOff()
{
sim.println("AT+SAPBR=0,1"); //GPRS OFF
}
void sendEmail()
{
Serial.println("SIM800L Send an email");
int sec = 1;
sim.println("AT+EMAILCID=1"); //set email parameters
sim.println("AT+EMAILTO=30");
// sim.println("AT+EMAILSSL=1");
sim.println("AT+SMTPSRV= " + server + port);
sim.println("AT+SMTPAUTH=1," + sender + "," + pass);
sim.println("AT+SMTPFROM="+ sender+ ","+ user1);
sim.println("AT+SMTPRCPT=0,0,"+ reciever+","+ user2);
sim.println("AT+SMTPSUB=" + subject);
sim.flush();
Serial.flush();
sim.println("AT+SMTPBODY=512");
delay(100);
sim.println("AT+SMTPBODY="+ body);
sim.println((char)26);
delay(1000);
// sim.println(0x1A);
sim.println("AT+SMTPSEND");
}
String _readSerial(){
while(sim.available()){
_output = Serial.readString();
}
return _output;
}
