No one else is providing this kind of information. Yet there are a lot of people interested in the subject. I fear those interested are not finding these videos.

Howdy, Mark. I was wondering if you could provide an example of how to send the Nextion RTC data to the Arduino so that time-based events could trigger on the Arduino based on the Nextion’s time and perhaps even make it so that once a day, week, etc. the Nextion could reach out to an NTP server to update its RTC so that after some period of time, say a year, events would still be triggering exactly when you would expect them to. I could live without the NTP update if the added complexity of that feature is something you’re not willing to tackle but the Nextion RTC to Arduino for time-based events is holding up my current project. As it stands I’m displaying the Nextion time on the Nextion screen, triggering Arduino events (actually an ESP32) via a separate RTC module all while also sending data to a php script which then sends sensor readings to MySQL which has its own time stamp. Needless to say, they’re all slightly out of sync and it’s driving me nuts. Eliminating just the RTC connected to the ESP32 so that the Nextion and ESP32 are in sync would help out tremendously. Anyway, keep the videos coming. You do an excellent job of breaking down the concepts and I frequently find that videos from the past which I never thought I’d need to know anything about become lifesavers when I hit the inevitable Nextion roadblock. Your work is appreciated.
