ESP8266 上的 WiFi 状态 1

WiFi Status 1 on ESP8266

我正在尝试将我的 Arduino Uno R3 + ESP8266 连接到 WiFi 连接,当我打印出来时它返回状态 1 WiFi.status(),现在有人知道它的真正含义是什么吗?解决方案?这是我的 ESP8266 代码:

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

// WiFi CREDENTIALS
const char *ssid = "xxxx";
const char *password = "xxxx";

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  Serial.println();
  Serial.println("Connect to: ");
  Serial.println(ssid);
}
    
void loop(){ 
  delay(5000);
  WiFi.mode(WIFI_STA);
  Serial.println();
  Serial.println("Connect to: ");
  Serial.println(ssid);
  Serial.println(WiFi.status());
  Serial.println(WL_CONNECTED);
  if (WiFi.status() != WL_CONNECTED) {
    WiFi.begin(ssid, password);
    delay(15000);
  }
  if (WiFi.status() == WL_CONNECTED) {
    Serial.println("From ESP Connected!");
  }
  else {
    Serial.println("From ESP Not Connected!");
  }
}

===更新=== 我试过使用智能手机的热点,第一次就成功了。

我在 Arduino 论坛上找到了 this。我希望它对你有用。根据下面的枚举,状态 1 表示没有 ssid。

typedef enum {
    WL_NO_SHIELD        = 255,   // for compatibility with WiFi Shield library
    WL_IDLE_STATUS      = 0,
    WL_NO_SSID_AVAIL    = 1,
    WL_SCAN_COMPLETED   = 2,
    WL_CONNECTED        = 3,
    WL_CONNECT_FAILED   = 4,
    WL_CONNECTION_LOST  = 5,
    WL_DISCONNECTED     = 6
} wl_status_t;

我自己也不确定,但是当我重新开始使用更简洁的代码时:

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

// WiFi CREDENTIALS
const char *ssid = "xxxx";
const char *password = "xxxx";

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  Serial.println("");
  Serial.print("Connecting");
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.print("Connected to ");
  Serial.println(ssid);
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
}


void loop() {
  if (WiFi.status() == WL_CONNECTED) {
    Serial.println("From ESP Connected!");
  }
  delay(5000);
}

我的直觉告诉我可能 WiFi.mode(WIFI_STA) 导致了错误?

顺便说一下,它已经成功了,感谢 Juraj 和 cbalakus 的帮助!
