Suggerimento ACCES POINT

Salve ragazzi
Un suggerimento , ho il seguente listato non riesco a trasformare il funzionamento in access point.

#include <ESP8266WiFi.h>
#include "indexl.h"

const char* ssid = " ";
const char* password = " ";

// Create an instance of the server
// specify the port to listen on as an argument
WiFiServer server(80);

int dac = 0;
int DigitalPin[] = {4, 12, 13};
int DacPin = 5;


// Auxiliary variables to store selected mode and settings 
int selectedMode = 0;
int timer = 0;
int ldrThreshold = 0;
int armMotion = 0;
int armLdr = 0;
String modes[4] = { "Manual", "Auto PIR", "Auto LDR", "Auto PIR and LDR" };

// Decode HTTP GET value
String valueString = "0";
int pos1 = 0;
int pos2 = 0;
// Variable to store the HTTP request
String header;
// Set web server port number to 80


void setup() {
  Serial.begin(115200);
  delay(10);


pinMode(4,INPUT);
pinMode(4, INPUT_PULLUP);
pinMode(12,OUTPUT);
pinMode(13,OUTPUT);
  
  // Connect to WiFi network
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);
  
  WiFi.begin(ssid, password);
  
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");
  
  // Start the server
  server.begin();
  Serial.println("Server started");

  // Print the IP address
  Serial.println(WiFi.localIP());
}

void loop() {
  // Check if a client has connected
  WiFiClient client = server.available();
  if (!client) {
    return;
  }
  
  // Wait until the client sends some data
  Serial.println("new client");
  while(!client.available()){
    delay(1);
  }
  
  // Read the first line of the request
  String command1 = client.readStringUntil('/');
  String command = client.readStringUntil('/');
  Serial.println(command1);
  Serial.println(command);


 client.println("<body><h1>ESP8266 Web Server</h1>");
            // Drop down menu to select mode
            client.println("<p><strong>Mode selected:</strong> " + modes[selectedMode] + "</p>");
            client.println("<select id=\"mySelect\" onchange=\"setMode(this.value)\">");
            client.println("<option>Change mode");
            client.println("<option value=\"0\">Manual");
            client.println("<option value=\"1\">Auto PIR");
            client.println("<option value=\"2\">Auto LDR");
            client.println("<option value=\"3\">Auto PIR and LDR</select>");






  

if (command == "digital") {
int pin, value;
pin = client.parseInt();
  Serial.println(pin);
if (client.read() == '/') {
value = client.parseInt();
digitalWrite(pin, value);
}
else {
value = digitalRead(pin);
}
client.print(F("digital,"));
client.print(pin);
client.print(F(","));
client.println(value);
}
else if (command == "dac"){
  int pin, value;
pin = client.parseInt();
if (client.read() == '/') {
value = client.parseInt();
dac = value;
analogWrite(pin, value);
}
else {
value = dac;
}
client.print(F("dac,"));
client.print(pin);
client.print(F(","));
client.println(value);
}
else if (command == "status") {
int pin, value;
client.print(F("status"));
for (int thisPin = 0; thisPin < 3; thisPin++) {
pin = DigitalPin[thisPin];
value = digitalRead(pin);
client.print(F("#"));
client.print(pin);
client.print(F("="));
client.print(value);
}
{
pin = DacPin;
value = dac;
client.print(F("#"));
client.print(pin);
client.print(F("="));
client.print(value);
}
{
value = analogRead(A0);
float lux=value;
client.print(F("#A0"));
client.print(F("="));
client.print(lux);
}
client.println("");
}
else {  // Prepare the response
  String s = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n";
  s += file1;  
  client.flush();


  


  // Send the response to the client
while(s.length()>2000)
{
  String dummy = s.substring(0,2000);
  client.print(dummy);
  s.replace(dummy," ");
}
  
  client.print(s);
  delay(1);
  Serial.println("Client disconnected");

  // The client will actually be disconnected 
  // when the function returns and 'client' object is destroyed
}
}

Beh attivi la modalità AP in questo modo (è uno spezzone di un mio programma che fa proprio quello):

  Serial.print("Starting AP... ");
  WiFi.mode(WIFI_AP);
  if ( WiFi.softAP(ssid, password, chan, 1) )
    Serial.println("Ready");
  else {
    Serial.println("FAILED!");
    while (1) { };
  }

Prova e facci sapere...

sostituendo inizia a darmi errore su client.print perchè vuole send.sever :-(

Posta il tuo codice modificato, e vediamo.
