This is the documentation for Espressif IoT Development Framework (). The NIST servers listen for a NTP request on port 123, and respond by sending a udp/ip data packet in the NTP format. So, this is possibly the least graceful way of getting the time w/ an ESP8266, but after spending days trying to learn how to program Arduino, most everything above was too advance for me to figure out, except that I could tell the time from the NTP server was not always coming back in the same position Some time ago, I published a project to configure an RTC connected to an Arduino using the time of your PC; today I’ll show you how to use an Internet time service with the esp32 chip. The RAW API is the only one usable without an OS, because it does not require threads and synchronization stuff, but of course can be used with a OS (as I'm doing to keep the memory usage and number of threads low). In embedded applications it's often necessary a clock, as accurate as possible. Let's start with the conservatory (winter garden) and the garden next to it. Some demos use uIP and some lwIP as the underlying embedded TCP/IP stack – and pre-date the introduction of FreeRTOS+TCP (FreeRTOS’s own scalable TCP/IP stack).
