Ciao a tutti, ho rilevato un prb durante la connessione wifi della scheda ESP8266:
Se configuro SSID e Pass funziona tutto compresa la ricezione dell'orario dal server ntp ("pool.ntp.org")
Se configuro anche, in modo statico, staticIP ,gateway e subnet non mi riceve più l'orario dal server.
Avete idea del perchè?
questo è il codice che stò provando:
#include <SPI.h>
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <ESP8266mDNS.h>
#define STASSID "NETGEAR"
#define STAPSK "nichiren"
const char* ssid = STASSID;
const char* password = STAPSK;

All'inizio del SetUp c'è una riga commentata che dovrebbe impostare la configurazione statica della connessione wifi.
Ho provato anche ad inserire solo lo staticIP ma non funziona...
Help!! Grazie
