我无法使用arduino成功连接到8266 wifi模块

Question

嗨，我是arduino编程的新手，我有一个问题。我已经成功设法使用esp8266模块显示WiFi，即当我运行我的代码时，esp8266模块创建一个wifi。它还要求输入密码，但之后没有成功连接的输出。我正在使用wifi.softAp（用户名，密码）方法创建wifi网络。我写了下面的代码：

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

const char* ssid = "Jeet";//Wifi username 
const char* password = "wifibin12"; //Wifi password 

ESP8266WebServer server(80); 

void handleRoot() { 
    server.send(200, "text/plain", "<h1>hello from esp8266!</h1>"); 
} 

void setup(void) { 
    // put your setup code here, to run once: 

Serial.begin(115200); 
//WiFi.mode(WIFI_AP); 
Serial.print("this is my pass"); 
Serial.print(password); 
WiFi.softAP(ssid, password); 
Serial.print("Setting soft-Ap ... "); 
// Wait for connection 

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


//If connection successful show IP address in serial monitor 
    Serial.println(""); 
    Serial.print("Connected to "); 
    Serial.println(ssid); 
    Serial.print("IP address: "); 
    Serial.println(WiFi.localIP()); //IP address assigned to your ESP 

    server.on("/", handleRoot);  //Which routine to handle at root location 

    server.begin();     //Start server 
    Serial.println("HTTP server started"); 

} 

void loop() { 
    // put your main code here, to run repeatedly: 
server.handleClient(); 
} 

当我运行代码时，我得到.............在串口监视器上不断输出。请帮助我解决这个问题，如果有人知道我做错了什么。建议也将不胜感激。

它陷入while循环。 Wifi.status（）在连接到wifi网络（返回到另一个接入点）时返回WL_CONNECTED。所以，如果你想只得到AP工作，你应该试试这个：

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

const char* ssid = "Jeet";   //Wifi username 
const char* password = "wifibin12"; //Wifi password 

ESP8266WebServer server(80); 

void handleRoot() { 
    server.send(200, "text/plain", "<h1>hello from esp8266!</h1>"); 
} 

void setup(void) { 
    // put your setup code here, to run once: 
    Serial.begin(115200); 
    Serial.print("this is my pass"); 
    Serial.print(password); 
    WiFi.softAP(ssid, password); 
    Serial.print("Setting soft-Ap ... "); 
    // Wait for connection 

//If connection successful show IP address in serial monitor 
    Serial.println(""); 
    Serial.print("AP name "); 
    Serial.println(ssid); 
    Serial.print("IP address: "); 
    Serial.println(WiFi.localIP()); //IP address assigned to your ESP 

    server.on("/", handleRoot);  //Which routine to handle at root location 

    server.begin();     //Start server 
    Serial.println("HTTP server started"); 

} 

void loop() { 
    // put your main code here, to run repeatedly: 
    server.handleClient(); 
} 

而且WiFi.localIP（）不返回AP的本地IP。默认值是192.168.4.1。
