RE: DNS fail #24

Closed charizord closed 3 years ago

charizord commented 4 years ago

Hello, truly sorry to be a bother. I found a solution to my issue with the dns fail, it seems that the "SetupPersistentWiFiConnection" sketch did not save the DNS addresses received by the router I had to add

IPAddress DNS = WiFi.dnsServer1(); IPAddress DNS2 = WiFi.dnsServer2(); WiFi.setDNS(DNS,DNS2);

for it to work, I do not know if this is an issue with my ESP8266 model / firmware but I thought it would interest you to know.

Now everything works fine, thank you for the great library and your time.

it is strange that you had to set the DNS IP addresses back. maybe there is a problem in the library. could you please provide AT commands log from SetupPersistentWiFiConnection and the code above so I can diagnose the problem?

I had exact same issue, I did a re-flash for the ESP-01 (AT 1.7.4) and AT+RESTORE, and now persistent mode works flawless. It might have been sufficient to only do AT+RESTORE.
