Ethernet with IP static and SNTP

[santanapablo1975]

Hi All,

Finally I got a static IP for Ethernet, modifying the function tcpip_adapter_dhcpc_stop, but when I test the SNTP example, is not possible to get the time from the server.

This behavior is normal or I missing something?

Regards

Thanks in advance.

Static IP you need to provide DNS server address

(Not a hardware question, wrong forum)

Hi WiFive,

It is a question again about Static IP and DNS..., the situation is as you mention is necessary to provide de DNS server address, so far is Ok and I have tested it, but my new question it is a issue inside the LWIP and/or the ESP32?... or better why with static IP the DNS is not resolved and we have to use the address?

Thanks in advance

DNS addresses are obtained with DHCP when using dynamic ip. When using static IP you need to provide it yourself. If you've ever configured the network address on a PC you'd see the same thing.
