RTC on ESP32 | 獸醫院評價網
Hi.Yes,theESP32hasbuitl-inRTC.However,wedon'thaveanyprojectaboutthatparticularsubject.Regards,
In the project https://randomnerdtutorials.com/esp32-date-time-ntp-client-server-arduino/[1] A Lee states, and Sara seems to agree, that a time update is gotten from the NTP server only once to set the internal RTC, then the RTC takes over and satisfies future time requests. I’m not convinced that is the case. Despite WiFi being turned off, access to the NTP server seems to continue to be available. If I omit the call to getLocalTime(&timeinfo) after the first pass, the
Serial.println(&timeinfo, "%A, %B %d %Y %H:%M:%S");result doesnt change each time it is invoked.References https://randomnerdtutorials.com/esp32-date-time-ntp-client-server-arduino/ (randomnerdtutorials.com)
