Board

DEVKIT V1, ESP32 Dev Module

Device Description

Clone ESP32 DEVKIT V1, Freenove ESP32-WROOM

Hardware Configuration

no

Version

v3.0.1

IDE Name

Arduino IDE

Operating System

Windows 11 and MACOS 14.5

Flash frequency

80 MHz

PSRAM enabled

no

Upload speed

921600

Description

Never gets time adjustment from BTP almost every time. Only once in a while successfully gets the time adjustment. Worked fine in version 2.0.17.

Sketch

ESP32 SimpleTime example.

Debug Message

no error message

Other Steps to Reproduce

Work fine in version 2.0.17 but not in 3.0 or above

I have checked existing issues, online documentation and the Troubleshooting Guide

commented

Should be NTP - not BTP.

commented

Issue confirmed. This is a a problem with esp_sntp_servermode_dhcp(1); // (optional) call.

commented

@wcwuttke - Please check PR #9884 that comments out esp_sntp_servermode_dhcp(1); // (optional) code line in the example.

commented

I commented out esp_sntp_servermode_dhcp(1); and it appeared to fix the problem. I rebooted the board three times successfully. However, the fourth and fifth time, got "No time available (yet)". Rebooted again and got the time. Rebooted again and got "No time available (yet)". Rebooted again and got the time. It looks like the problem is still there intermittently.

commented

This is interesting... I was getting 100% success while I had debug output as Verbose.
But when I tried it with no debug output I also see the issue youo are reporting about the problem being still there.

It may also be related to another fix from the https://github.com/espressif/arduino-esp32/pull/9862/files
It seems that it must wait for the WiFi interface to really get started.

Indeed removing esp_sntp_servermode_dhcp(1); is not the fix.

I have applied the fix from #9862 here and it seems to improve the success rate to 8 out of 10.

Could you apply the change to libraries/WiFi/src/STA.cpp into the begin() function?

bool STAClass::begin(bool tryConnect) {
  if (!WiFi.enableSTA(true)) {
    log_e("STA enable failed!");
    return false;
  }
  if (!waitStatusBits(ESP_NETIF_STARTED_BIT, 1000)) {
    log_e("Failed to start STA!");
    return false;
  }
  if (tryConnect) {
    return connect();
  }
  return true;
}
commented

@me-no-dev - Could you please also take a look into it?

commented

@wcwuttke - I think I got the solution: I changed the NTP server to const char *ntpServer1 = "time.google.com";
It has worked 100% of 20 resets of the board.

commented
commented

The change in STA.cpp is irrelevant. esp_sntp_servermode_dhcp(1); should be the line after WiFi.begin() as explained in it's comment, but will also not cause NTP to fail, it will just not take it from DHCP if it offers NTP server.

With that said, I am trying to replicate the issue and I can not. I got No time available (yet) once and a couple of seconds later, it got the time just fine. Restarted tenths of times.

commented

me-no-dev,
I don't know what your configuration is, but the only way I can get this sketch to work reliably is with version 2.0.17. With 3.0.1, it will work once in a while, but mostly fails.

commented

I don't know what your configuration is

The example as-is. Nothing else. My SSID and PASS

commented

Did you wait after you got the message to eventually get the NTP or not?

commented
commented

@wcwuttke I see, but I can not reproduce here. I made more than 30 restarts with the sketch as-is and could not get it to fail once. I suspect something in your environment is to blame

commented
commented

ESP32-WROVER-E (ESP32 v3) on a Mac M1MAX (should not matter) and my router is Mikrotik without any special settings for NTP. Sketch is SimpleTime with adjusted SSID, PASS and time offset for my zone. From all reboots I got No time available (yet) only once for just one time, after which time was updated before next 5 seconds expires.

Any chance you can try in a different network environment? I have no idea why 2.x worked but 3.x fails for you...

commented
commented

can you turn core debug to level Verbose and paste the output before setup on those ESPs? I'll try to use the same

commented
commented

yes. will test tomorrow

commented
commented

can you please not reply via email? formatting the data you paste is impossible this way and it's very hard to read

commented

I agree. However, to me it looks OK on Github. I had a lot of trouble trying to cut & paste from the Arduino IDE, and I have never used the debug features before. (I have always used "Serial.print" for debugging.) Let me try compiling on the Win 11 machine to see what is happening with it. Maybe if I knew exactly what you are looking for I could try to get it.

commented

Email replies do not support Markdown

commented

After you paste it here and not through email. we can fix the format (though that is something you should do yourself). Email replies are ok if you are just commenting, but pasting logs and code is not good

commented

Something very strange has happened. When I compile with 3.0.1, the app repeatedly crashes. I go back to 2.0.17, all is well. Go back to 3.0.1 continuous crashing.

That sounds like the issue is in your environment. Or are you using another sketch and not the SimpleTime?

commented

I am using SimpleTime. I just tested on the Win11 machine with the same results. Keeps on crashing - both 3.0.0 and 3.0.1. I revert to 2.0.17 and all is well. Now it is 3 different machines with 3 different OS's.

commented

I do have rev1 wrovers here so will test tomorrow

commented

Just for fun, I tested using Arduino 1.8.19 on the Win11 machine. Same result. OK with 2.0.17, keeps crashing with 3.0.1.

commented

As long as we are testing with two different chips, we will never have the same testing environment. I will order a WROVER board today to see what happens on this end.

commented

Things are getting stranger. I compiled a few other example projects and came back to SimpleTime. Amazingly enough it compiled and ran OK - but, sometimes got the time, sometimes it didn't. I captured the verbose debug output of 3 reboots - both getting time and not getting time - to a file which is attached.

and my output with the same module as yours (many restarts an no fail):

Got time adjustment from NTP!

I set up a Win10 machine as an NTP server. In the SimpleTime sketch I used the Win10 IP address in ConfigTime(). This configuration works like a charm (3.0.1). So....to me it looks like a DNS problem of some sort. I have an XFinity router which from time to time has had DNS problems. Let me reboot that and let's see what happens. Progress is being made.

commented

Well, rebooting the router didn't help.

update: Used IP address for time.google.com (216.239.35.4) instead of hostname and it works well.
Also for IP address of pool.ntp.org. It looks that at least I've found a workaround.
