How to get NTP time using an Arduino and ESP-01 via Hardserial or Softserial?

Projects Programming

Hello,

I'm already using NTPClient library and a Wemos or NodeMCU board without any problem.

But now, I want to simply connect an Arduino UNO to an ESP-01 via hardserial or softserial, and get time from an NTP server (preferably using the mentioned library).

I've searched all the net but I couldn't find any comprehensive code to do it. All the codes are using the shields. But I want to use the cheap ESP-01 for the project.

one option
flash AT firmware into esp-01. the AT Lobo version of AT 1.7, because it can return the time as epoch
and then use my WiFiEspAT library in Uno

3

or use Robin's Serial Input Basics to communicate between the 2.

4

the esp8266 has SNTP in SDK. no need to use the NTPClient library

Many thanks for your replies.

Is there any solution I could fetch time using the default ESP-01 firmware?
Actually I'm not going to change the firmware, because I want to use remotexy at the same time and it won't work with any other firmware.

my recommendation uses AT firmware. the latest classic (NonOS SDK) version. only it is a custom build which can return the time as epoch
