[SOLVED] Simple WebServer doesn't work

[GeorgeFlorian1]

Hardware:

Board: ESP32 DEVKIT1

Core Installation version: 1.0.1-git this one

IDE name: Arduino IDE

Flash Frequency: 80Mhz

PSRAM enabled: no

Upload Speed: 115200

Computer OS: Linux Mint 19.1 Mate

The following code returns a timeout and I don't know why. How can I fix it ?

Code: Select all

#include <WiFi.h>
#include <WebServer.h>
#include <HTTPClient.h>

char* ssid = "ssid";
char* pass = "cocoscocos";

WebServer Server;

void rootPage() {
  char content[] = "Hello, world !";
  Server.send(200, "text/plain", content);
}

void setup () {
  delay(1000);
  Serial.begin(115200);
  Serial.println();

  Server.on("/", rootPage);
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, pass);
  while (WiFi.status() != WL_CONNECTED) {
    delay(300);
  }
  Serial.println("WiFi Connected: " + WiFi.localIP().toString());
  Server.begin();
}

void loop() {
  
}

Maybe you need to wait until the wifi is connected before you start the server.

In loop:

server.handleClient();

In loop:

server.handleClient();

This fixed it. Thanks !
