@brutzler hrhr, I'm working on a sntp lib to work with the Time library from the Arduino project literally just now. Is that what you are looking for? If so, give me an hour and I put a first version on github
I "need" it for time controlled warmwater-heater. Want to keep a software-clock, sychronized via internet on startup and every x hours.
Actually it doesn't use a handmade udp call, expressif provides an sntp client, my library is just a wrapper for that so it can be used with the mentioned time lib
the ESP has ntp support
@brutzler yeah, that should work, I'm running my wordclock with that
