Hi Ivan,
do you know what kind of data (and the quantity) you must manage?LoRa has the possibility to send a structured packet or a simple string, so as needed we can create a reliable and efficient transmission protocol, better than modbus which is widely used but has physical limitations.

Hi Ivan,
I think you can use the fixed transmission like in the examples in this article.If you give our some details we can try to be more specific.
And if you are Italian remember that the articles are also in Italian.

Hi Anton,
I check the link and the source, and all are correct.
Explain which step you make to do the build.
Bye RenzoHi Anton,
you can read all that information in the relative articles.

Hi Gzegorz,
you can find some examples and documentation herePCF8574 i2c digital I/O expander: Arduino, esp8266 and esp32, basic I/O and interrupt – Part 1

Hehehehhe… but I think the problem is the sending frequencies of the email, probably GMail block the multiple sending if the second email is too close to the previous.
Bye RenzoHi Fix,
SoftwareSerial for esp32 is not a standard library, esp32 can use HardwareSerial with custom pins.
You can find all in the official documentation.
Bye RenzoHi ozzy,
probably GMail blocked the attempt to send an email too close to the previous email (prevent spam).
Try to add adelay(10000);or more before the secondEmail2();Bye Renzo
Hi Anton,
to develop a web solution for that machine I need the hardware.
No response from Makerbase, you can try to write to him for that support (蔡钦栋 ).
Bye RenzoHi deti,
I think isn’t possible, e220 have an embedded cryptography system, but overall It’s based on new llcc68.
You can try with the less recent e32 based on sx1276, but I’m not sure about result.
Bye RenzoHi jimh,
I already answered in your previous post here.
