Hi Amaia,
I test the library, and it works correctly.
Rewrite the code as usual and retry.

Hi,
thanks for your feedback, I think your information can be very useful.

Hi,
It’s very strange; It’s more likely that there are some problems with the power supply and the pull-up resistor.

Hi,
no, restore to an external 5v power supply and try to change the pullup resistor o try to remove It.

Hi phnahes,
It’s possible that you connect on Arduino the power pin of e32 to 5v and to the esp32 to the 3.3v?

Hi Luxed,
Other people tell me that they have problems with Marlin firmware. I think it manages communication in a different way, and I think it can’t work with this implementation.

Hi Sid,
thanks for your feedback, if you can share your code, I think can be usefully for a lot of people.

Hi Andrecolz,
yes, the combination for the address is ADDH*ADDL, so 255*255.

For the max CHAN value, you must check the datasheet; every device has an It range.

I think the enc28j60 need more resources respect w5500.

Ahhh ok sorry Erjon,
you can reduce memory usage by disabling the attachments.

Hi William,
if you want to use a Structure, you must use fixed size variables. String is dynamic, and the receiver can’t know the correct size.

Try to use something like this.

Have struct Message{
int switchState;
char[13] timeStamp;
}message;

It’s possible that firewall block some port and It doesn’t work, however, it’s important to note that the Arduino Uno does not support SSL, which is required for secure email transmission.

Therefore, you would need to use a specific email provider that allows non-SSL communication or explore alternative email sending methods, such as using a third-party service or API designed to work with IoT devices like the Arduino.

Hi FC3,
you can use TinyGSM library.
Pratically you must connect your device (there is a long list of supported device) and It offer a series of method to do HTTP request or MQTT request.

Hi Elkez,
no I support only UART version of the modules.

Hi Erjon,
try to follow the steps for Arduino UNO (if you use It); then there are a lot of topics about how to configure the send grid to send email.

Send emails with attachments (v2.x library): Arduino Ethernet – 1
