NTP time server in ASCII via HTML - I am looking for a simple solution

Question

I'm looking for an NTP time server that displays the current time in text form via html after entering a web address. We exclude watch pages of the type because the microprocessor chip in which it is to work cannot handle such a page.

The servers are 99% synchronised with NTP anyway. So you just need to find one that can be read from html. Or make your own. Code: JavascriptLog in, to see the code

Anonymous · Answer

This example is wrong because the uC will not write a javascript interpreter.

On any server on the network you have access to, write yourself a short script in php

echo a string with the data you are interested in (I have not met a server that does not have clock synchronisation).

And isn't it easier to implement the classic NTP. If you're going to have the answer in a string, you're probably going to trim it and convert it to inty anyway.

It is much easier to implement the classic NTP String -> int definitely easier than implementing NTP

Samuraj · Answer

But NTP is not that difficult. Since you have sending/receiving frames it's downhill from there.

You send a frame

The server sends you a frame from which you have to extract

Log in, to see the code

The rest is just splitting.

NTP as the name suggests

, is a standalone protocol, and in a formal sense there is no NTP in ASCII. It is a very old protocol, from the days when resources were conserved, and among other things includes the concept of compensating for packet "time of flight" in networks of the time.

My guess is that use in the "native" version gives a much smaller need than HTTP for RAM/CPU so with puncet times .... (unless the software already has a relationship with HTTP)

I use the firmware with NTP in my ESP plugged into the AVR
I retrieve the time using the AT+CIPNTP command
in response I get Time: 22:48:25 01/15/2016 GMT+01
All I need to do now is parse this into a struct

Samuraj · Answer

Is it possible to know which firmware this is? Are there any sources for it?

michalko12 · Answer

There is NTP, there is also SNTP. The latter protocol is simpler to implement and I suspect there are plenty of examples of how to decode data from this protocol.

tomson5 · Answer

I don't remember the source. Probably github.com. Type in google esp8266 firmware ntp you will find for sure. I'm happy to help if you have any questions.
