Hi

I tried to run UdpNtpClient example, but it doesn't work. It sends packet but doesn't get the answer
i have changed NTP server to other but it did not help. Of course i also changed mac and ip address.
Did someone succeed running this example ? What i do wrong

nobody tried that example ?

which example? there are more than one on the internet....

I've used - Arduino Playground - DS1307OfTheLogshieldByMeansOfNTP - many times succesfully.

Can your PC fetch NTP packets? blocked by the router?

recall to keep at least a minute between two calls as the NTP servers sometimes block IP addresses that send to many requests

Maybe, maybe not, I just don't know. :slight_smile:
