我无法使用 arduino 成功连接到 8266 wifi 模块

Question

您好，我是 arduino 编程新手，但遇到了问题。我已经成功地使用 esp8266 模块显示了 wifi，即当我运行我的代码时，esp8266 模块创建了一个 wifi。它还要求输入密码，但之后没有成功连接的输出。我正在使用方法 wifi.softAp(username,password) 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，我会在串行监视器上连续输出......如果有人知道我做错了什么，请帮我解决这个问题。建议也将不胜感激。

它陷入了 while 循环。 Wifi.status() 在连接到 wifi 网络（连接到另一个接入点）时返回 WL_CONNECTED。所以如果你想让 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();
}

并且 WiFi.localIP() 不会返回 AP 的本地 IP。默认为 192.168.4.1。
