Hi George,
you can find the explanation of the configuration here.

Hi George,
read the comments on sketch, that a configuration for esp8266, and you have arduino and esp32.

Hi Daniel,
I fix the problem, and now work; I will release the new version with a working example soon.

No, sorry, switching the library after compiling isn’t possible for the structure of the library.

Hi George,
I think you can follow these steps.

First, check the complete wiring (all pins, not M0 and M1 to GND and 3.3v). You can find the connection schema in this article.

Ebyte LoRa E32 device for Arduino, esp32 or esp8266: library – 2

Then understand the communication type you need

Ebyte LoRa E32 device for Arduino, esp32 or esp8266: fixed transmission – 4

And finally, configure the device.

EByte LoRa E32 Web Manager: description, configure and demo (esp8266, esp32) – 2

Change only the wiring from one device and another.

Hi don,
don’t worry It remove only the Less secure app because It want to standardize the use of Password Application, the other way to get EMailSender put to work.

You can find information about the use of Application password in the article

Hi Grzegorz,
when you use INPUT It expects that the default state is LOW, to set an input pin to low you must add a pull-down resistor on your circuit.

Azzzz!!! This is a giant bug.
Thanks, I’m going to fix it in all my libraries.

Would you like to share your work? It seems very, very interesting and helpful for the people.

No Mike,
You must set the correct SMTP server and all the other parameters of your email provider.

[Renzo Mischianti]

Hi Mike,
the example that I attach It’s a real example, but you must configure your provider.
Bye Renzo

[Renzo Mischianti]

I attach a basic example but remember enc28j60 does not support SSL so you can’t use a service like Gmail.
Check this article
Send email with attachments (v2.x library): Arduino Ethernet – 1

And there are a lot of topics about SendGrid configuration and similar.

It’s strange, try to re-read the configuration stored, anche check if It’s correctly stored.

Hi sup_arman,
you forget to close (and free) the structure container with rc.close() command.

	// If something available
  if (e220ttl.available()>1) {
	  // read the String message
#ifdef ENABLE_RSSI
	ResponseStructContainer rc = e220ttl.receiveMessageRSSI(sizeof(Deneme));
  struct Deneme d = *(Deneme*) rc.data;
  Serial.println(d.type);
  //e220ttl.flush();
  //e220ttl.receiveMessageRSSI(sizeof(Deneme));
  //e220ttl.cleanUARTBuffer();
  //Serial.println(d.msg);
  //Serial.println(d.arman);
#else
	ResponseStructContainer rc = e220ttl.receiveMessage(sizeof(Deneme));
  struct Deneme d = *(Deneme*) rc.data;
  Serial.println(d.type);
  //e220ttl.flush();
  //rc = e220ttl.receiveMessage(sizeof(Deneme));
  //e220ttl.cleanUARTBuffer();
  //Serial.println(d.msg);
  //Serial.println(d.arman);
#endif
	// Is something goes wrong print error
	if (rc.status.code!=1){
		Serial.println(rc.status.getResponseDescription());
	}else{
		// Print the data received
		Serial.println(rc.status.getResponseDescription());
		//Serial.println(rc.data); //this was for string transmission only 
#ifdef ENABLE_RSSI
		Serial.print("RSSI: "); Serial.println(rc.rssi, DEC);
#endif
	}
        rc.close();
  }

Try

EMailSender emailSend(email_login.c_str(), email_password.c_str());

Hi Claudecate,
probably there are spaces added to the end of string to grow all byte array length

Try something similar to

int writeStringToEEPROM(int addrOffset, const String &strToWrite)
{
  byte len = strToWrite.length();
  EEPROM.write(addrOffset, len);
  for (int i = 0; i < len; i++)
  {
    EEPROM.write(addrOffset + 1 + i, strToWrite[i]);
  }
  return addrOffset + 1 + len;
}
int readStringFromEEPROM(int addrOffset, String *strToRead)
{
  int newStrLen = EEPROM.read(addrOffset);
  char data[newStrLen + 1];
  for (int i = 0; i < newStrLen; i++)
  {
    data[i] = EEPROM.read(addrOffset + 1 + i);
  }
  data[newStrLen] = '\0'; 
  *strToRead = String(data);
  return addrOffset + 1 + newStrLen;
}

where the addrOffset is the start of eeprom and you can use String variable

String user = "ciccio";
String password = "passwd";
writeStringToEEPROM(0, user);
writeStringToEEPROM(32, password);

and to read

String user;
String password;
readStringFromEEPROM(0, &user);
readStringFromEEPROM(32, &password);

Ahhh ok..
Too late 😛
