Can’t connect to Gmail

[Sergio]

Hi, i use this code to check if i have wifi at home.
I will change the purpose later.
For the moment i want
-Have one wifi connection (this part works)
Turn on a led wen i have internet connection and turn off when I don’t have. (this work too)
The idea was to send a email when i have internet connection again.
So i use this code to send the email, but he don’t work.

The code

———————————————-

#include <WiFiNINA.h>
#include <SPI.h>
#include “Arduino.h”
#include <EMailSender.h>

 

char ssid[] = “ma-maison”; // your network SSID (name)
char pass[] = “4445555SSSSEER???”; // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0; // your network key Index number (needed only for WEP)
int status = WL_IDLE_STATUS; //connection status
WiFiServer server(80); //server socket
//mod ping
String hostName = “www.google.fr”;
int pingResult;
// fin mod ping
// mod mail

//EMailSender emailSend(“sergio”, “dddd1111?”, “sergio@gmail.com”, “smtp.gmail.com”, 465);  i have tried this combination too

EMailSender emailSend(“sergio”, “dddd1111?”);

// fin mod mail

WiFiClient client = server.available();

int ledPin = 2;

void setup() {
Serial.begin(9600);
pinMode(ledPin, OUTPUT);
while (!Serial);

enable_WiFi();
connect_WiFi();

server.begin();
printWifiStatus();

// mod mail

EMailSender::EMailMessage message;
message.subject = “teste”;
message.message = “finalemente”;

EMailSender::Response resp = emailSend.send(“sergio@laposte.net”, message);

Serial.println(“Sending status: “);
Serial.println(resp.code);
Serial.println(resp.desc);
Serial.println(resp.status);

// fin mod mail

}

void loop() {

sergio();

}

void printWifiStatus() {
// print the SSID of the network you’re attached to:
Serial.print(“SSID: “);
Serial.println(WiFi.SSID());

// print your board’s IP address:
IPAddress ip = WiFi.localIP();
Serial.print(“IP Address: “);
Serial.println(ip);

// print the received signal strength:
long rssi = WiFi.RSSI();
Serial.print(“signal strength (RSSI):”);
Serial.print(rssi);
Serial.println(” dBm”);

Serial.print(“To see this page in action, open a browser to http://&#8221;);
Serial.println(ip);
}

void enable_WiFi() {
// check for the WiFi module:
if (WiFi.status() == WL_NO_MODULE) {
Serial.println(“Communication with WiFi module failed!”);
// don’t continue
while (true);
}

String fv = WiFi.firmwareVersion();
if (fv < “1.0.0”) {
Serial.println(“Please upgrade the firmware”);
}
}

void connect_WiFi() {
// attempt to connect to Wifi network:
while (status != WL_CONNECTED) {
Serial.print(“Attempting to connect to SSID: “);
Serial.println(ssid);
// Connect to WPA/WPA2 network. Change this line if using open or WEP network:
status = WiFi.begin(ssid, pass);

// wait 10 seconds for connection:
delay(10000);
}
}
void sergio(){
// mod ping
Serial.print(“Pinging “);

Serial.print(hostName);

Serial.print(“: “);

pingResult = WiFi.ping(hostName);

if (pingResult >= 0) {

Serial.print(“SUCCESS! RTT = “);

Serial.print(pingResult);

Serial.println(” ms”);

digitalWrite(ledPin, HIGH);

} else {

Serial.print(“FAILED! Error code: “);

Serial.println(pingResult);

digitalWrite(ledPin, LOW);

}

delay(5000);

}

——————————- end code——————–

I have this result

 

Attempting to connect to SSID: ma-maison
SSID: ma-maison
IP Address: 002.01.0.30
signal strength (RSSI):-37 dBm
Sending status:
2
Could not connect to mail server
0

 

Thanks for any help

Thanks,
I have done this before but the first time didn’t work.

Thank you very much.
