Hi,
I found these informations

The error message “Relaying disallowed” will occur in the following cases.
From address that you are trying to add in SMTP client might not be listed in your Send Mail as section (in Zoho Mail). Please ensure that the email address that you are trying to use is one of the From addresses present in your Send Mail as section. Refer help to locate Send Mail as page.
If “Outgoing Server Requires Authentication” option is not enabled in the SMTP client. Ensure that the settings entered are correct by referring this link help page.

what is the port you use for SMTP server?

Can you try with gmail (with application password or insecure app)?

Thanks, Paul,
I think many people had written to It, after only a couple of weeks they contacted me.
If you need a preview of the library, contact me, I must write and test all the examples, and I have already written the first two articles about that.
Thanks again Renzo

Sorry, Arkadiusz,
I lost your reply, but in brief, do you have in mind to standardize the protocol of BeePrint?
And how do you intend to connect to the 3D printer?
All suggestion is appreciated; if you have a route to follow, we can think about that.

Hi Alejandro,
I think the problem is the debounce time and setting; if an input pin goes up then goes down in the interval, you lost the change.
Try to set

#define READ_ELAPSED_TIME 10

To 0 so you remove debounce, and you must use interrupt.

You can refer to the pcf8574 example.

Hi Sezgin,
No, E32 doesn’t have RSSI; you must select E22 or E220 (library available soon).

Hi ps2chiper,
Have you had time to try if the solution works for you?

Hi Davide,
It’s a good idea, I must check if have enough resources to manage mutual authentication..

Hi Gilles,
no sorry, not yet, I hope next week I put on my Eclipse Sloeber and check It.

Can you write here a description of the program?
It will be very usefully when I’ll go to examine It.

Hi Theo,
I don’t have a DTU to compare the configuration, but if you have some problem, you can contact Ebyte, who changes his organization to help and better support the developer.

You can also try to configure a BROADCAST message instead of a transparent transmission.

Please give me feedback about that.

Hi Theo,

I can try and make a tutorial for the PCB design through easy eda if interested in your blog?

Sure, if you can do that. It’s fantastic!.

Hi Gilles,
Update the library to the last version (now 2.4.3); there are some memory fixes than retry.

Hi Morne,
you need a USB to serial adapter to program an esp01.

ESP-01 modules programming board

Try a telnet from your PC to check if there are some firewall rules versus the smtp server. So we can exclude network problem.

Hi Mauro,
I have in mind an auth solution, but probably without https (too resource and memory), so I must think better how to do.
Thanks for sharing Renzo

Hi Theo,
I’m happy that you had found the problem.
If you’d like to share your project write to me without problem.

Hi Lakshminarauyana,
I think It’s more complex the problem, from here It seems that the spi pins can be changed only via begin.

But when you declare GxIO

GxIO_Class io(fspi, /*CS=5*/10, /*DC=*/44, /*RST=*/43); // arbitrary selection of 17, 16

evenif you declare CS pin, inside It start spi with begin() standard parameter.

void GxIO_SPI::init()
{
  if (_cs >= 0)
  {
    digitalWrite(_cs, HIGH);
    pinMode(_cs, OUTPUT);
  }
  if (_dc >= 0)
  {
    digitalWrite(_dc, HIGH);
    pinMode(_dc, OUTPUT);
  }
  if (_rst >= 0)
  {
    digitalWrite(_rst, HIGH);
    pinMode(_rst, OUTPUT);
  }
  if (_bl >= 0)
  {
    digitalWrite(_bl, HIGH);
    pinMode(_bl, OUTPUT);
  }
  reset();
  _spi.begin();
}

but this command start SPI with standard pins

void SPIClass::begin(int8_t sck, int8_t miso, int8_t mosi, int8_t ss)
{
    if(_spi) {
        return;
    }

    if(!_div) {
        _div = spiFrequencyToClockDiv(_freq);
    }

    _spi = spiStartBus(_spi_num, _div, SPI_MODE0, SPI_MSBFIRST);
    if(!_spi) {
        return;
    }

    if(sck == -1 && miso == -1 && mosi == -1 && ss == -1) {
#if CONFIG_IDF_TARGET_ESP32S2
        _sck = (_spi_num == FSPI) ? SCK : -1;
        _miso = (_spi_num == FSPI) ? MISO : -1;
        _mosi = (_spi_num == FSPI) ? MOSI : -1;
        _ss = (_spi_num == FSPI) ? SS : -1;
#elif CONFIG_IDF_TARGET_ESP32C3
        _sck = SCK;
        _miso = MISO;
        _mosi = MOSI;
        _ss = SS;
#else
        _sck = (_spi_num == VSPI) ? SCK : 14;
        _miso = (_spi_num == VSPI) ? MISO : 12;
        _mosi = (_spi_num == VSPI) ? MOSI : 13;
        _ss = (_spi_num == VSPI) ? SS : 15;
#endif
    } else {
        _sck = sck;
        _miso = miso;
        _mosi = mosi;
        _ss = ss;
    }

    spiAttachSCK(_spi, _sck);
    spiAttachMISO(_spi, _miso);
    spiAttachMOSI(_spi, _mosi);

}

I don’t know if can solve but try to change void GxIO_SPI::init() by pass the sck, miso, mosi, ss parameter.

Bye Renzo
