Can't connect to my home router

[wolfrose]

Hello,

I'm trying to connect my esp32 to my wifi rounter, using Arduino examples.

This is the code:

Code: Select all

/*
  WiFiAccessPoint.ino creates a WiFi access point and provides a web server on it.

  Steps:
  1. Connect to the access point "yourAp"
  2. Point your web browser to http://192.168.4.1/H to turn the LED on or http://192.168.4.1/L to turn it off
     OR
     Run raw TCP "GET /H" and "GET /L" on PuTTY terminal with 192.168.4.1 as IP address and 80 as port

#include <WiFi.h>
#include <WiFiClient.h>
#include <WiFiAP.h>

#define LED_BUILTIN 2   // Set the GPIO pin where you connected your test LED or comment this line out if your dev board has a built-in LED

// Set these to your desired credentials.
const char *ssid = "myssid";
const char *password = "1234";

WiFiServer server(80);


void setup() {
  pinMode(LED_BUILTIN, OUTPUT);

  Serial.begin(115200);
  Serial.println();
  Serial.println("Configuring access point...");
  
  WiFi.disconnect(true);
  delay(10);

  // You can remove the password parameter if you want the AP to be open.
  WiFi.softAP(ssid, password);
  IPAddress myIP = WiFi.softAPIP();
  Serial.print("AP IP address: ");
  Serial.println(myIP);
  server.begin();

  Serial.println("Server started");
}

void loop() {
  WiFiClient client = server.available();   // listen for incoming clients
  if (client) {                             // if you get a client,
    Serial.println("New Client.");           // print a message out the serial port
    String currentLine = "";                // make a String to hold incoming data from the client
    while (client.connected()) {            // loop while the client's connected
      if (client.available()) {             // if there's bytes to read from the client,
        char c = client.read();             // read a byte, then
        Serial.write(c);                    // print it out the serial monitor
        if (c == '\n') {                    // if the byte is a newline character

          // if the current line is blank, you got two newline characters in a row.
          // that's the end of the client HTTP request, so send a response:
          if (currentLine.length() == 0) {
            // HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
            // and a content-type so the client knows what's coming, then a blank line:
            client.println("HTTP/1.1 200 OK");
            client.println("Content-type:text/html");
            client.println();

            // the content of the HTTP response follows the header:
            client.print("Click <a href=\"/H\">here</a> to turn ON the LED.<br>");
            client.print("Click <a href=\"/L\">here</a> to turn OFF the LED.<br>");

            // The HTTP response ends with another blank line:
            client.println();
            // break out of the while loop:
            break;
          } else {    // if you got a newline, then clear currentLine:
            currentLine = "";
          }
        } else if (c != '\r') {  // if you got anything else but a carriage return character,
          currentLine += c;      // add it to the end of the currentLine
        }

        // Check to see if the client request was "GET /H" or "GET /L":
        if (currentLine.endsWith("GET /H")) {
          digitalWrite(LED_BUILTIN, HIGH);               // GET /H turns the LED on
        }
        if (currentLine.endsWith("GET /L")) {
          digitalWrite(LED_BUILTIN, LOW);                // GET /L turns the LED off
        }
      }
    }
    // close the connection:
    client.stop();
    Serial.println("Client Disconnected.");
  }
}

Although my esp8266 worked just fine without problems.
I tried different examples for the esp32 but all didn't work.

This is screenshot for my serial monitor output:


What to do ?

Check your SSID is visible? I have found the wifi performance of some boards is below par...

#include "WiFi.h"

void setup(){
Serial.begin(115200);
WiFi.mode(WIFI_STA);
WiFi.disconnect();
delay(100);
}

void loop(){
Serial.println("Start scan");
int n = WiFi.scanNetworks();

if (n == 0) {
Serial.println("no networks found");
} else {
Serial.print(n);
Serial.println(" networks found");
for (int i = 0; i < n; ++i) {
Serial.print(i + 1);
Serial.print(": ");
Serial.print(WiFi.SSID(i));
Serial.print(" (");
Serial.print(WiFi.RSSI(i));
Serial.print(") ");
Serial.print(" [");
Serial.print(WiFi.channel(i));
Serial.print("] ");
String encryptionTypeDescription = translateEncryptionType(WiFi.encryptionType(i));
Serial.println(encryptionTypeDescription);
delay(10);
}
}
Serial.println("Scan done");
Serial.println("");
delay(10000);
}

String translateEncryptionType(wifi_auth_mode_t encryptionType) {
switch (encryptionType) {
case (0):
return "Open";
case (1):
return "WEP";
case (2):
return "WPA_PSK";
case (3):
return "WPA2_PSK";
case (4):
return "WPA_WPA2_PSK";
case (5):
return "WPA2_ENTERPRISE";
default:
return "UNKOWN";
}
}

Yep I've done this test before and it's working and displaying all the networks nearby.

Mine is -65 strength. It's just 3 meters away.

But the problem is that I can't launch webserver example codes.

Hi,

Somehow it worked ! It connected to the simplewebserver example.

Thanks man for the help
