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, using UDP on port 123. Through this port, the server can communicate with the...
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 (...
void sntpfn() { u32_t ts = 0; ts = sntp_get_current_timestamp(); // 获取当前的偏移时间 os_printf("current time : %s\n", sntp_get_real_time(ts)); // 获取真实时间 if (ts == 0) // 网络时间获取失败 { os_printf("did not get a valid time from sntp server\n"); } else...

The ESP32 can easily get the time from an NTP server using the built-in time library. Once the ESP32 gets the time from the NTP server, it can be used to synchronize the internal clock of the device. This can be done using the built-in time library as well....
