Hi,
the usage of Serial2 can’t work, because you do the begin and inside the library I do begin again.
To use custom pin on esp32 you can refer this article

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

You can’t do

    LoRa_E32 e32ttl100(&Serial2, AUX_PIN, M0_PIN, M1_PIN);
    Serial2.begin(9600, SERIAL_8N1, RX2_PIN, TX2_PIN);
    e32ttl100.begin();

because you start the serial 2 times
you must use something like this

LoRa_E32(RX2_PIN, TX2_PIN, &Serial2, AUX_PIN, M0_PIN, M1_PIN);

Hi Josh,
check the logic level of M0 and M1 if raise correctly, with 5v power sometime It’s hard to change.
Check if are high.
If you have a FDTI use software serial to debug or to control the e32, debug information It’s important to discover the problem.

Hi Claudio,
the configuration is wrong, you don’t initialize the Serial, the library do it for you.
You can look at this topic with the same esp32 configuration problem.

EByte LoRa e32 not working on esp32: sends a random number, the other reads

If you need more information ask without problem.

Hi Josh,
please give us a connection schema, so we can help you.
And try to uncomment the line in the library

#define LoRa_E32_DEBUG

and retry.

Hi
I try to contact Ashining, but no response from they.
Sorry I think this productor have very low interest and support to Arduino ecosystem.

Hi Gilles,
yes you don’t see any difference because I think you must use SSClient for secure connection, and I must add secure support to the library.
I don’t have a w5500 shield, if I find one I try to add support.

You can try to add https://github.com/OPEnSLab-OSU/SSLClient to the library and instantiate the SecureClient with this.

Hi Orvasson,
I had lost your message (I need a moderator).

But what Paloy said is correct, you can connect various i2c devices and communicate with them via the device address.

Some devices have the address configurable through pins such as the various pcf8574 pcf8591 etc ..

PCF8574 i2c digital I/O expander

other can be programmed via code, other have fixed address.

You can check the address of the devices connected with a simple program like this:

/*
 * i2c scanner
 * Renzo Mischianti www.mischianti.org
 */
#include <Wire.h>

void setup() {
  Wire.begin();
  Serial.begin(115200);
  while (!Serial) {delay(100);};
  Serial.println();
  Serial.println("I2C Scanner");
}

void loop() {
  byte error, address;
  int nDevices;
  Serial.println("Scanning...");
  nDevices = 0;
  for(address = 1; address < 127; address++ ) {
    Wire.beginTransmission(address);
    error = Wire.endTransmission();
    if (error == 0) {
      Serial.print("I2C device found at address 0x");
      if (address<16) {
        Serial.print("0");
      }
      Serial.println(address,HEX);
      nDevices++;
    }
    else if (error==4) {
      Serial.print("Unknow error at address 0x");
      if (address<16) {
        Serial.print("0");
      }
      Serial.println(address,HEX);
    }
  }
  if (nDevices == 0) {
    Serial.println("No I2C devices found\n");
  }
  else {
    Serial.println("done\n");
  }
  delay(5000);
}

Hi Joergen,
sorry to write so late, I add support for LittleFS in this versione of EMailSender
Send email with attachments (EMailSender v2.x library): esp32 and esp8266 – 2

And also update a library of FTP Server to support LittleFS.
FTP server on esp8266 and esp32

Hi makac,
It’s very difficult to debug without a device.
I try to ask to the Ashining some send me some devices to adapt the library.
Bye Renzo

[Renzo Mischianti]

Hi Orvasson,

the SPI protocol pins are

static const uint8_t SS = 34;
static const uint8_t MOSI = 35;
static const uint8_t MISO = 37;
static const uint8_t SCK = 36;

from 34 to 37.

The pin 46 is a simple pin but can’t used for output for some HW limitation, you can use It only in digital input.

Hi Asterios,
I add some trick and a simple program to calculate step on this article.
If you have difficult write here I try to help you.

Hi Sergio,
Thanks, I fixed It.

When you give me the account I try to send email with EMailSender and an esp8266, and It work correclty

 

the library It’s ok, the problem is the provider.

Bye Renzo

[Renzo Mischianti]

Hi Gilles,

I send email without problem from GMail with esp8266 to orange.fr account, the problem is that Orange block the other provider.

So you must contact your  provider and try to unlock sendgrid, or they must suggest you an unencrypted service like send grid.

Hi Gilles,

you can try 25, 2525, or 587 port for unencrypted connection, if you can’t use this ports mean that in your network these ports are blocked and you can’t use that.
