Hi everyone,

I get these errors:

exit status 1

Compilation error: stray '\357' in program

altho I checked that I have no special charachters somewhere around. Can you help me troubleshoot this problem?

This is my code. I hope you can read this fine?

#include<ESP8266mDNS.h>
#include<ESP8266WebServer.h>
#include<ESP8266WiFi.h>

//#include <ESP8266WiFi.h>
//#include <ESP8266WebServer.h>
//#include <ESP8266mDNS.h>

ESP8266WebServer server (80);

const char* SSID = "iPhone-FOC";
const char* password= "12345678";

// following for the name of: http://name_esp.local/
const char* dns_name = "esp8266";

int d1 = 2;
int d1_status = 0;

void setup() 
{
 Serial.begin(115200);
  Serial.println("ESP gestartet");
  pinMode(d1, OUTPUT);

  WiFi.begin(SSID, password);

  Serial.print("Verbindung wird hergestellt ...");
  while (WiFi.status () != WL_CONNECTED)
  {
      delay(500);
      Serial.print(".");
  }
  Serial.println();

  Serial.print("Verbunden! IP-Adresse: ");
  Serial.println(WiFi.localIP());

  if (mDNS.begin(dns_name)) {
    Serial.println("DNS gestartet, erreichbar unter: ");
    Serial.println("http://" + String(dns_name) +  ".local/");
    }

server.onNotFound([] (){
    server.send(404, "text/plain", "Link wurde nicht gefunden");
});

server.on("/", [] () {
    server.send(200, "text/plain", "ESP-Startseite!");
});

server.on("/relais_on", [] () {
  server.send(200, "text/plain", "Relais an");
  relais_on();
});

server.on("/relais_off", [] () {
  server.send(200, "text/plain", "Relais aus");
  relais_off();
});

server.begin();
Serial.println("Webserver gestartet.");
}

void loop() {
  server.handleClient();
}

void relais_on() {
    digitalWrite(d1, HIGH);
}

void relais_off(){
  digitalWrite(d1, LOW);
}

You do have special characters in your code, it starts with a UTF-8 BOM, see Compiler error about stray characters - #3 by PieterP.

Oh so the problem is my ‘‘‘#‘‘‘

So I’ll need to save it as UTF-8?

I’ll try that soon.

Thanks in advance :slight_smile:

The # itself is fine, the BOM is before that, it's invisible.

Got it thanks! I’ll try this weekend!
