To obtain epoch time with ESP32 through the NTP server, we’ll follow the client-server model. Our ESP32 development board acts as the client and will connect to the widely accessible NTP server, pool.ntp.org,
In this tutorial, you’ll learn how to properly get the time with the ESP32 for your timezone and consider daylight saving time (if that’s the case). The ESP32 will request the time from an NTP server, and the time will be automatically adjusted for your timezone with or without day...
Learn how to request date and time from an NTP Server using the ESP32 with Arduino IDE. Getting date and time is useful in data logging projects to timestamp readings. To get time from an NTP Server, theESP32needs to have an Internet connection and you don’t need additional hardware (...
