Electronic, 3D printing and embedded programming
This guide demonstrates how to send emails with attachments from STM32 microcontrollers using SSL encryption, like Gmail. It covers using w5500 and enc28j60 for network connectivity and SD cards and SPI Flash for storage. With detailed setup instructions and coding examples, it enables secure email communication in STM32-based projects.
I would like to introduce version 2 of the EMailSender library, a great evolution compared to version 1, with support for Arduino with w5100, w5200 and w5500 ethernet devices and enc28J60 clone devices, support for esp32 and esp8266 and finally (from version 2.2.0) support for all Arduino (SAMD) devices using the WiFiNINA library (Arduino UNO WiFi Rev.2, Arduino NANO 33 IoT, Arduino MKR 1010 and Arduino MKR VIDOR 4000 WiFi etc.). Now you can add attachments also, loaded from storage device like SD or SPIFFS.
I would like to monitor the status of my ABB Aurora inverter (formerly Power One now Fimer). So with a WeMos D1 mini I create a monitoring station with web interface, notifications and more.
Notification is a basic feeature of every monitoring system, here we check how to configure the device to send email with errors.
