hello.
i tried to make a connection to wifi using arduino mega and cytron shield esp wifi rev 2.0. After i upload and run the program i get this message from serial monitor “Couldn’t get a wifi connection”. my wifi use wpa2 PSK type.
this is my code.
#include <WiFi.h>
char ssid = “wifiname”; // your network SSID (name)
char pass = “1234f56”; // your network password
int status = WL_IDLE_STATUS; // the Wifi radio’s status
void setup() {
// initialize serial:
Serial.begin(9600);
// attempt to connect using WPA2 encryption:
Serial.println(“Attempting to connect to WPA network…”);
status = WiFi.begin(ssid, pass);
// if you’re not connected, stop here:
if ( status != WL_CONNECTED) {
Serial.println(“Couldn’t get a wifi connection”);
while(true);
}
// if you are connected, print out info about the connection:
else {
Serial.println(“Connected to network”);
}
}
void loop() {
// do nothing
}
