Hello
Could someone take a look at my code where is the error of my project with Esp8266 which is crashing in the wifiMonager configuration web when I near the wifi password configuration button
here the program to send data through the serial port.
#include <ESP8266WiFi.h>
#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager

                                        // Defina o nÃºmero da porta do servidor web para 80

WiFiServer server(80);
// VariÃ¡vel para armazenar a solicitaÃ§Ã£o HTTP
String header;
void setup() {
Serial.begin(9600);

// WiFiManager
// InicializaÃ§Ã£o local. Uma vez que seu negÃ³cio esteja concluÃdo, nÃ£o hÃ¡ necessidade de mantÃª-lo por perto
WiFiManager wifiManager;
wifiManager.autoConnect("AutoConnectAP");
Serial.println("Connected.");
server.begin();
initWifi();
}
void loop(){
}
void initWifi() {
WiFiClient client = server.available(); // Listen for incoming clients

if (client) { // If a new client connects,
Serial.println("New Client."); // print a message out in the serial port
String currentLine = ""; // make a String to hold incoming data from the client
while (client.connected()) { // loop while the client's connected
if (client.available()) { // if there's bytes to read from the client,
char c = client.read(); // read a byte, then
Serial.write(c); // print it out the serial monitor
header += c;
if (c == '\n') { // if the byte is a newline character
// if the current line is blank, you got two newline characters in a row.
// that's the end of the client HTTP request, so send a response:
if (currentLine.length() == 0) {
// HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
// and a content-type so the client knows what's coming, then a blank line:
client.println("HTTP/1.1 200 OK");
client.println("Content-type:text/html");
client.println("Connection: close");
client.println();

        // Web Page Heading
        client.println("<body><h1>ESP8266 Web Server</h1>");
        // The HTTP response ends with another blank line
        client.println();
        // Break out of the while loop
        break;
      } else { // if you got a newline, then clear currentLine
        currentLine = "";
      }
    } else if (c != '\r') {  // if you got anything else but a carriage return character,
      currentLine += c;      // add it to the end of the currentLine
    }
  }
}
// Clear the header variable
header = "";
// Close the connection
client.stop();
Serial.println("Client disconnected.");
Serial.println("");

}
}
