Description:
I am using SimpleTime example. I have added second and third NTP server, but when I change first NTP server's address to wrong one, it cannot obtain time. configTzTime() and configTime() are not using second and third NTP servers.
Sketch: (leave the backquotes for code formatting)
#include <WiFi.h>
#include "time.h"
const char* ssid = "xxx";
const char* password = "xxx";
const char* ntpServer = "wrong.ntp.org";
const char* ntpServer2 = "pl.pool.ntp.org";
const char* ntpServer3 = "3.pl.pool.ntp.org";
const long gmtOffset_sec = 3600;
const int daylightOffset_sec = 3600;
void printLocalTime()
{
struct tm timeinfo;
if(!getLocalTime(&timeinfo)){
Serial.println("Failed to obtain time");
return;
}
Serial.println(&timeinfo, "%A, %B %d %Y %H:%M:%S");
}
void setup()
{
Serial.begin(115200);
Serial.printf("Connecting to %s ", ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println(" CONNECTED");
configTzTime("CET-1CEST,M3.5.0,M10.5.0/3", ntpServer, ntpServer2, ntpServer3);
//configTime(gmtOffset_sec, daylightOffset_sec, ntpServer, ntpServer2, ntpServer3); //same situation
printLocalTime();
WiFi.disconnect(true);
WiFi.mode(WIFI_OFF);
}
void loop()
{
delay(1000);
printLocalTime();
