First i was thinking on using a real time clock with battery backup (the traditional way) but hey, i would be alot nicer to use the NTP protocol to receive the time. I thought I’ll just find some existing code, upload it and it’s done. 49 B This project provides several libraries for Arduino on the ESP8266. NTP protocol vs. I prefer to program the ESP8266 using the Arduino IDE, but the same result can be achieved with LUA code or via AT Commands. This project started as an improvement of Ray Burnette's Tardis Time that basically has the same hardware elements, but doesn't send time/date information using standard protocols, so a small listener application must be developed in every different device to be synchronized. Date & Time (+ zone) with Arduino Time Library TimeLib. Pedro Minatel - Embedded Systems > ESP8266 > Date and time on ESP8266 using NTPdate and time protocols: daytime, time and ntp Since the very first practical computers started to work, the idea of having them time synchronized was revolving around. Contents [show]. If all of the timing goes correct, the request will be returned, assembled into a string, parsed, and the date and time displayed on the OLED. Time keeping on the ESP8266 is technically quite challenging. Then you can use it [the ESP8266] with the Arduino IDE just like your existing Arduino …I'm playing with the ESP8266 and NTP, and added a function in a ESP8266 Library to get the NTP time. It would be possible to do this with NTP, but that would require more coding. Extract and print current time and date; The sntp client performs a time synchronization with servers from us.

To use the software, unzip it and copy/move the ESP8266NTPClock directory from the zip file into your Arduino directory. Currently the op mode command "set date ntp" always uses the server "0. Second, using an NTP server for the time and date allows me to use the NodeMCU Lua firmware's rtctime and sntp modules. Thanks a lot Andreas for you kind response. I don't have a suggestion for a NTP client on an arduino sending over serial to a ESP8266. By Craig A
