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。我已经成功地使用esp8266模块显示了wifi，也就是说，当我运行我的代码时，esp8266模块创建了wifi。它还要求输入密码，但之后没有成功连接的输出。我使用wifi.softAp(用户名，密码)的方法来创建wifi网络。我写了以下代码：

#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.............串行监视器上连续输出。如果有人知道我做错了什么，请帮助我解决这个问题。建议也将不胜感激。

它被while循环卡住了。当连接到wifi网络(到另一个接入点)时，Wifi.status()返回WL_CONNECTED。因此，如果你想让AP正常工作，你应该尝试这样做：

#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();
}

并且WiFi.localIP()不返回AP的本地ip。默认值为192.168.4.1。
