I am trying to connect my ESP32 to my Wifi Router using Arduino IDE but it is not connecting & giving a connection failed or disconnected status. I also confirmed it is scanning all the available Wifi Networks but not connecting to my router. I even tried with another ESP32 board but the problem is still there.
I tried this code below. This code would scan/give the available Wifi networks and it did. Also, I was expecting this code to run smoothly but my ESP32 won't connect to my Wifi router.
#include<WiFi.h>
const char *ssid = "my_SSID";
const char *password = "my_Password";
void setup()
{
Serial.begin(115200);
delay(2000);
WiFi.mode(WIFI_STA);
WiFi.disconnect();
delay(100);
Serial.println("scan start");
// WiFi.scanNetworks will return the number of networks found
int n = WiFi.scanNetworks();
Serial.println("scan done");
if (n == 0) {
Serial.println("no networks found");
} else {
Serial.print(n);
Serial.println(" networks found");}
// Connect to my network.
WiFi.begin(ssid,password);
// Check Status of your WiFi Connection
int x = WiFi.status(); // If x=3 (Connected to Network) & If x=6 (Disconnected from Network)
Serial.print("WiFi Connection Status is ");
Serial.println(x);
while(WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("WiFi Connection Failed...");
WiFi.disconnect();
WiFi.reconnect(); }
//Print local IP address and start web server
Serial.println("\nConnecting");
Serial.println("");
Serial.println("WiFi connected.");
Serial.println("ESP32 IP address: ");
Serial.println(WiFi.localIP());
}
void loop() {}
Try this code:
#include<WiFi.h>
const char *ssid = "YourSSID";
const char *password = "YourPassword";
void initWiFi() {
WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);
Serial.print("Connecting to WiFi ..");
while (WiFi.status() != WL_CONNECTED) {
Serial.print('.');
delay(1000);
}
Serial.println(WiFi.localIP());
}
void setup() {
Serial.begin(115200);
initWiFi();
Serial.print("RRSI: ");
Serial.println(WiFi.RSSI());
}
void loop() {
// put your main code here, to run repeatedly:
}
