I use the same code in Telnet, it can work.
If someone can give me a hand, thanks....
Here is the code:
/*
*/
#include <ESP8266WiFi.h>
const char* ssid = "So-net";
const char* password = "XXXXX";
const char* host = "smtp.gmail.com";
void setup() {
Serial.begin(115200);
delay(10);
// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}
int value = 0;
void loop() {
delay(5000);
++value;
Serial.print("connecting to ");
Serial.println(host);
// Use WiFiClient class to create TCP connections
WiFiClient client;
const int httpPort = 2525;
if (!client.connect("smtpcorp.com", httpPort)) {
Serial.println("connection failed");
return;
}
else
Serial.println("connection ok");
//client.print("HELO smtp.gmail.com\r\n");
//Serial.println("HELO smtp.gmail.com");
client.print("EHLO 192.168.0.3\r\n");
Serial.println("EHLO 192.168.0.3");
byte respCode;
byte thisByte;
int loopCount = 0;
respCode = client.peek();
while (client.available())
{
Serial.print(client.read(), HEX);
}
client.print("AUTH LOGIN\r\n");
Serial.println("AUTH LOGIN");
client.print("xxxxxxxxxxxx==\r\n");
Serial.println("ID");
client.print("xxxxxxx\r\n"); //SECRET password Base64 Encoded
Serial.println("PassWord");
//client.print("HELO smtp.gmail.com\r\n");
client.print("MAIL FROM:<chentaoko@gmail.com>\r\n");
Serial.println("MAIL FROM:<chentaoko@gmail.com>");
client.print("RCPT TO:<chentaoko@gmail.com>\r\n");
Serial.println("RCPT TO:<chentaoko@gmail.com>");
client.print("DATA\r\n");
Serial.println("DATA");
client.print("From: Home Alarm <chentaoko@gmail.com>\r\n");
Serial.println("From: Home Alarm <chentaoko@gmail.com>");
//os_sprintf(buff, "MAIL FROM:<%s>\r\n", smtp_conn->user);
client.print("To: <chentaoko@gmail.com>\r\n");
Serial.println("To: <chentaoko@gmail.com>");
client.print("Subject: ALARM ALERT!\r\n");
Serial.println("Subject: ALARM ALERT!");
client.print("\r\n");
client.print("\r\n");
client.print("alarmMessage");
//
client.print(".\r\n");
Serial.println(".");
client.print("QUIT\r\n");
Serial.println("QUIT");
Serial.println();
Serial.println("closing connection");
}
