Hi,
i wanted to implement a WifiServer on the ESP32 with Arduino. I tried different examples from ESP8266, but i didn't get it working.
I updated the latest Version of Arduino for ESP32 from github today.
I setup the ESP32 as AccessPoint and startet the WifiServer. I can connect and send a request. The ESP32 sends the response, but then resets the connection, according to curl. So InternetBrowsers and curl are showing me errors.
Can you please have a look what I have done wrong? Or is this a bug?
Error with curl:
curl http://192.168.4.1
<!DOCTYPE HTML>
<html><h1><Hello World!</h1></html>
curl: (56) Recv failure: Connection reset by peer
Here is my Sketch:
#include <WiFi.h>
const char* WIFI_SSID = "ESP-Accesspoint";
const char* WIFI_PASSWORD = "geheimPasswort";
WiFiServer server(80);
void setup(void) {
Serial.begin(115200);
WiFi.mode(WIFI_AP);
WiFi.softAP(WIFI_SSID, WIFI_PASSWORD);
server.begin();
}
void loop(void) {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait until the client sends some data
Serial.println("New client");
delay(1);
// Read the first line of the request
String request = client.readStringUntil('\r');
Serial.print("Request: ");
Serial.println(request);
client.flush();
String s = "HTTP/1.1 200 OK\r\n";
s += "Content-Type: text/html\r\n\r\n";
s += "<!DOCTYPE HTML>\r\n";
s += "<html><h1><Hello World!</h1></html>\r\n";
Serial.println("Response:");
Serial.println(s);
client.println(s);
client.flush();
delay(1);
Serial.println("Client disonnected"); //When method ends
}
Thanks in advance and Greetings
