hi everyone, i try to use my esp32 as a web server bur i have a problem. When i do it by creating an Access Point with the esp32, that works really well. But when i do it by connecting my esp32 to the wifi nothing is happening. When i go to the url, it says this : "192.168.1.75 took too long to respond". here is my code :
// Import required libraries
#include <WiFi.h>
#include <ESPAsyncWebServer.h>
#include <AsyncTCP.h>
#include <SPIFFS.h>
#include <LiquidCrystal.h>
#include <HTTPClient.h>
// Replace with your network credentials
const char* ssid = "***********";
const char* password = "***************";
// set the LCD number of columns and rows
int lcdColumns = 16;
int lcdRows = 2;
// set LCD address, number of columns and rows
LiquidCrystal lcd(19, 23, 18, 17, 16, 15);
// Set LED GPIO
const int ledPin = 23;
// Stores LED state
String ledState;
// Create AsyncWebServer object on port 80
AsyncWebServer server(80);
// Replaces placeholder with LED state value
String processor(const String& var){
Serial.println(var);
if(var == "STATE"){
if(digitalRead(ledPin)){
ledState = "ON";
}
else{
ledState = "OFF";
}
Serial.print(ledState);
return ledState;
}
return String();
}
void setup(){
// initialize LCD
lcd.begin(16, 2);
// turn on LCD backlight
// Serial port for debugging purposes
Serial.begin(115200);
pinMode(ledPin, OUTPUT);
// Initialize SPIFFS
if(!SPIFFS.begin(true)){
Serial.println("An Error has occurred while mounting SPIFFS");
return;
}
WiFi.mode(WIFI_STA);
// Connect to Wi-Fi
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to WiFi..");
Serial.println((String)"[+] RSSI : " + WiFi.RSSI() + " dB");
Serial.print("[+] ESP32 IP : ");
Serial.println(WiFi.localIP());
}
// Print ESP32 Local IP Address
Serial.println(WiFi.localIP());
lcd.setCursor(0, 0);
lcd.print("IP address is ");
lcd.setCursor(0, 1);
lcd.print(WiFi.localIP());
// Route for root / web page
server.on("/", HTTP_GET, [](AsyncWebServerRequest *request){
request->send(SPIFFS, "/index.html", String(), false, processor);
});
// Route to load style.css file
server.on("/style.css", HTTP_GET, [](AsyncWebServerRequest *request){
request->send(SPIFFS, "/style.css", "text/css");
});
// Route to set GPIO to HIGH
server.on("/on", HTTP_GET, [](AsyncWebServerRequest *request){
digitalWrite(ledPin, HIGH);
request->send(SPIFFS, "/index.html", String(), false, processor);
});
// Route to set GPIO to LOW
server.on("/off", HTTP_GET, [](AsyncWebServerRequest *request){
digitalWrite(ledPin, LOW);
request->send(SPIFFS, "/index.html", String(), false, processor);
});
// Start server
server.begin();
}
void loop(){
}
