Sim808 email +SMTPSEND: 61

[d_r_elec]

Bonjour à toutes et à tous.
Je suis sur un projet avec un ESP32 et un module SIM808, je voudrai que celui ci m’envoie un mail via Gmail quand il reçoit un SMS. J’ai essayer plusieurs solution mais rien n'y fait, j’ai toujours la même erreur: +SMTPSEND: 61

const int boot = 4;

String lecture_sms = "";
String mot_clef = "";

void setup() {
  pinMode(boot, OUTPUT);
  digitalWrite(boot, HIGH);
  delay(1000);
  digitalWrite(boot,LOW);

  Serial.begin(115200);
  Serial2.begin(115200);
  delay(3000);
  init_gsm();
  //send_SMS();
}

void loop() {
  //updateSerial();
  if (Serial2.available()){
    lecture_sms = Serial2.readString();
    lecture_sms.trim();
    mot_clef = lecture_sms.substring(48,70);
    Serial.println(mot_clef);
    if(mot_clef == "Recuperation"){
      Serial.println("MATCH");
      send_email();
    }
  }
}

void updateSerial(){
  delay(1000);
  while (Serial.available())
  {
    Serial2.write(Serial.read());
  }
  while (Serial2.available())
  {
    Serial.write(Serial2.read());
  }
}

void init_gsm(){
  Serial2.println("AT");
  updateSerial();
  Serial2.println("AT+CPIN=0000");
  updateSerial();
  Serial2.println("AT+CSQ");
  updateSerial();
  Serial2.println("AT+CCID");
  updateSerial();
  Serial2.println("AT+CREG?");
  updateSerial();
  Serial2.println("AT+CFUN=1");
  updateSerial();
  Serial2.println("AT+CMGF=1");
  updateSerial();
  Serial2.println("AT+CNMI=1,2,0,0,0");
  updateSerial();
  
  
}

void send_email(){
  Serial2.println("AT+SAPBR=3,1,CONTYPE,GPRS");
  updateSerial();
  Serial2.println("AT+SAPBR=3,1,APN,mmsbouygtel.com");
  updateSerial();
  Serial2.println("AT+SAPBR=1,1");
  updateSerial();
  Serial2.println("AT+SAPBR=2,1");
  updateSerial();
  Serial2.println("AT+SAPBR=0,1");
  updateSerial();
  Serial2.println("AT+EMAILCID=1");
  updateSerial();
  Serial2.println("AT+EMAILTO=30");
  updateSerial();
  Serial2.println("AT+SMTPSRV = smtp.gmail.com, 465");
  updateSerial();
  Serial2.println("AT+SMTPAUTH = 1, *****@gmail.com, *****");
  updateSerial();
  Serial2.println("AT+SMTPFROM = *****@gmail.com, CALYPSO");
  updateSerial();
  Serial2.println("AT+SMTPRCPT=0,0,*****@gmail.com, KEVIN");
  updateSerial();
  Serial2.println("AT+SMTPSUB = DONNEES");
  updateSerial();
  Serial2.println("AT+SMTPBODY = 10");
  updateSerial();
  Serial2.println("AT+SMTPBODY = 0123456789");
  updateSerial();
  Serial2.write(26);
  updateSerial();
  Serial2.println("AT+SMTPSEND");
  updateSerial();
}
