Neo. Administrator. 19,118, 3,359. A Slightly Better NTP Client for the ESP32 (ESPWROOM32) on macOS Catalina. Currently have two ESP8266 modules testing some Blynk apps, whereI'm not so happy with the Blynk business model for developers, but that's another story. So, with two of my ESP8266s currently "busy", I decided to work on the ESP32, and ....
In this project we are going to make an ESP32 based internet clock to display the internet time over a 16x2 LCD display. The most used and popular protocol for synchronizing time over the internet is NTP (Network Time Protocol). The reference time is taken from a connected radio clock or atomic clock. Here, we are going to fetch the time data. ESP32 NTP Example.ino diagram.json.

Still on the journey to complete an "upcoming project", "ESP32 NTP Temperature Probe Cooking Thermometer With Steinhart-Hart Correction and Temperature Alarm" is an Instructable showing how I add an NTP temperature probe, piezo buzzer and software to my capacitive touch Instructable "ESP32 Capacitive Touch Input Using "Metallic Hole Plugs" for Buttons" to create a simple but accurate cooking .... The format of this tuple is (year, month, month-day, hour, min, second, weekday, year-day). As you can see, this means that my ESP32 currently thinks that it's the 1st of January in the year 2000...the dawn of a new millennium. Just like Morpheus did to Neo in The Matrix, I'm gonna shatter that illusion and give it a red pill from the NTP server.
NTP Server Working To get the date and time with our ESP32 through the NTP server, the server will operate in the client-server model. We will use the NTP server: pool.ntp.org which is easily accessible for everyone worldwide. Our ESP32 development board will be the client and will connect to the NTP server through UDP on port 123.
