Hi Zwartoog,

Yes, I’ve looked at your code and we have certainly some similarities in our code.
Mine seems to be working stable at the moment.

I will probably use some of your code for a CPM sensor display 😉

Thx!

I was able to create my own NTP sync with the help from this source: https://medium.com/@joeldavidw/nixie-clock-ntp-sync-remote-switch-4b6ad7b686d

I then improved the code and added some failsafes e.g. when no internet connection is there or the UDP package size is not 48, … it retries to fetch the NTP and if that fails after 3 consecutive tries it goes over to GPS

My code can be viewed/ downloaded from my GitHub page: https://github.com/DonZalmrol/GRA-AFCH-IN-12-Arduino-Nixie-clock-kit-with-NTP

Cheers!

Ah fantastic looking forward for other solutions/ insights.
Do you experience any other issues regarding your NTP solution?

[DonZalmrolParticipant]

Hi, do you have a link to your firmware and more information about this? 🙂

[DonZalmrolParticipant]

Apologies for digging this up from the past, but I’ve followed similar instructions on how to incorporate the NTP, it works but its buggy.
The UDP package size drops from 48 (What it should be for NTP) to 0 causing my RTC to default to 1970… I’ve created topic for my issue.

As you can see the UDP package size drops from 48 (What it should be for NTP) to 0 and then after a while the WifiESP gets a timeout followed by a Data packet send error.

What happens then is that the clock sets its NTP to 1970 (default UNIX time) or messes up the DST (jumping +1 or +2) or even displaying a completely different date from who knows where…

If it’s a known issue with the NTP udp packages on Arduino, could I fetch this and create an exception e.g try-catch-finally?
