NTP server giving time after long time

[burkulesomesh43]

Hi all,
I have used sntp example from esp idf and modified it as per my use as folllows-->>>

Code: Select all

void sntp_task(void *pvParameter) {

	sntp_setoperatingmode(SNTP_OPMODE_POLL);
	sntp_setservername(0,"asia.pool.ntp.org");
	sntp_init();

	time_t now;
	struct tm timeinfo;
	struct tm *tmp;
	time(&now);
	localtime_r(&now, &timeinfo);
	while(timeinfo.tm_year < (2019 - 1900))
	{   
		printf("Time not set, trying...\n");
		vTaskDelay(5000 / portTICK_PERIOD_MS);
		time(&now);
                localtime_r(&now, &timeinfo);
      }

	while(1)
	{
		
		time(&now);
		setenv("TZ", "UTC-5:30", 1);
		tzset();
		tmp = localtime( &now );
		strftime(Timebuffer, sizeof(Timebuffer), "%d/%m/%Y  %I:%M:%S %p", tmp);
	
		vTaskDelay(999 / portTICK_RATE_MS);
	}
}

but sometimes it does not gives time instantly or can't get time.
Don't know what is the problem.
please help me out to solve this.

Hi,

We have used ntp into our project but we have applied all server which are used for ntp server configuration. So, We haven't faced any issue like that.

Would you please try with that as provided into sntp example and check with that?

It might be like sometime you will not get time from server and you will get it from second server as quickly as possible.

can you please provide example you have used?
how can we use two servers?

Hi,

Please find attached code for reference purpose for SNTP Init Process.

Code: Select all

void initialize_sntp (void)
{
	sntp_setoperatingmode(SNTP_OPMODE_POLL);
	sntp_setservername(0, "pool.ntp.org");
	sntp_setservername(1, "europe.pool.ntp.org");
	sntp_setservername(2, "uk.pool.ntp.org ");
	sntp_setservername(3, "us.pool.ntp.org");
	sntp_setservername(4, "time1.google.com");
	sntp_init();
}

Let me know if still issue after using that.

I am getting this issue again.
Actually it gives that issue sometimes only but don't know, why?

There is no logs generated. it only tries to reach NTP server continuosly.

Hi,

We have tried same way at our end and didn't face any issue till now. I just want to clarify that are you sending NTP request after getting proper IP and external connectivity into device itself?

Yes, I am sending NTP request after connecting the device to Network.

Yes, I am sending NTP request after connecting the device to Network.

Then it should be worked?

Would you please try with master IDF as well with just sample STA example in which after getting IP event just ping to SNTP Server accordingly.

If still it is not working then there might be chances into your network as well or try with Hot-Spot as well with external network connectivity.
