WiFiClient is not a built-in type like int or char. It's a class that must be defined (usually in a header file) before you can create an instance of it. In your example code, there is no such definition, but you are trying to instantiate WiFiClient in run_mode.cpp. Perhaps run_mode.cpp must include WiFiClient.h.Im using the esp32 and as it has wifi, im trying to use it as a NTP Client in order to get the correct time without the rtc module. So far it is working, i get the correct time, but i only get it like this "HH:MM:SS", but I need to get it as variables.I am currently working on an ESP8266 with the Arduino IDE. I try to implement an ESP8266 in STA mode as multicast receiver. I was writing my code with the help of this documentation. Especially the

UDP broadcast listener example for ESP32. Finally something that could be taken 99% from my ESP8266 code. Only difference is the spelling of the required header file. In ESP8266 the header file is WiFiUDP.h, in ESP32 the header file is WiFiUdp.h. This are the small traps you can get stuck when moving code from the ESP8266 to the ESP32.The WiFi library is very similar to the Ethernet library, and many of the function calls are the same. For additional information on the WiFi shield, see the Getting Started page and the WiFi shield hardware page. To use this library #include < WiFi.h> Examples.

In this tutorial we’ll show you how to get date and time using the ESP32 and Arduino IDE. Getting date and time is especially useful in data logging to timestamp your readings. If your ESP32 project has access to the Internet, you can get date and time using Network Time Protocol (NTP) – you don’t need any additional hardware.

I used a 12V regulated power supply to power both the ESP8266 breakout board and LED strip. The LEDs draw about 0.6 amps per meter, according to Adafruit, so plan accordingly. Now it's time to make the actual circuit. We need to hook up the +12V from the power supply to the V+ pin on the ESP8266 breakout board and to the +12V on the LED strip.

  • In this third tutorial dedicated to creating a web interface for DIY projects based on ESP8266, we will learn how to recover the time from a Network Time Protocol (NTP) time server. The Arduino and the ESP8266 and ESP32 WiFi modules do not have a real-time clock (except for a few specific exceptions).

  • In the previous examples (HTTP, WebSockets) we've only used TCP connections, but NTP is based on UDP. There are a couple of differences, but it's really easy to use, thanks to the great libraries that come with the ESP8266 Arduino Core.
  • If you then point it to e.g. folder "c:\Espressif\examples\hello_world", you'll import the hello_world program into your Eclipse workspace. To build and upload the example, you will have to figure out which serial portal the ESP8266 is connected to, using the Windows Device Manager.

  • WiFi Kit 32 NTP Clock is another of my learning forays into the numerous features of the ESP32. During startup, the clock obtains the current date and time from an ntp server, adjusts for time zones (see the Software step), writes the result to the ESP32 rtc (real time clock), then uses the ESP32 rtc to update the built in OLED display with the date and time.
