Re: How to send a e-mail (ESP32-Arduino)
Email is sent using the SMTP protocol. There are libraries and examples, and the basic protocol isn't too difficult to implement.
But it's not that simple, most SMTP servers won't accept mail from a simple SMTP client implementation. They require authentication and TLS encryption. That makes it harder.
Probably better to use MQTT, and let a cloud-based MQTT broker handle sending email.

Alternatively, look at ifttt.com webhooks (previously known as maker channel). Send a trigger using http GET or POST from the ESP. TLS is optional. The HTTPClient library is helpful for this. When IFTTT receives the trigger, it can send email, SMS, tweet, etc.

Hello all
A very nice solution exists:
Use this library:

And this program:

Code: Select all
[/
#include <WiFi.h>
#include <sendemail.h>
/*
* to enable/disable debug on Serial: Please see sendemail.h

*/
const char* SSID = "------";
const char* PASS = "----------";
void setup()
{
Serial.begin(115200);
delay(10);
Serial.println("");
Serial.print("Connecting To ");
WiFi.begin(SSID, PASS);
while (WiFi.status() != WL_CONNECTED)
{
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi Connected");
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
// create object
SendEmail e("smtp.gmail.com", 465, "email_account@gmail.com", "password", 5000, true);
// Send Email
e.send("<email_account@gmail.com>", "<email_to_send@gmail.com>", "test", "bonjour XXXX");
}
void loop()
{ }
]
It works very well !! ;)
