ESP8266 中 Wifi 库的 return 代码是什么意思?
What does the return code of the Wifi Libary in an ESP8266 mean?
#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>
#ifndef STASSID
#define STASSID "wlanName"
#define STAPSK "wlanPassword"
#endif
const char* ssid = STASSID;
const char* password = STAPSK;
const char* host = "api.github.com";
const int httpsPort = 443;
const char fingerprint[] PROGMEM = "5F F1 60 31 09 04 3E F2 90 D2 B0 8A 50 38 04 E8 37 9F BC 76";
void setup() {
Serial.begin(115200);
delay(5000);
Serial.println();
Serial.print("connecting to ");
Serial.println(ssid);
WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);
while (true) {
delay(500);
Serial.print(WiFi.status());
}
}
void loop() {
// put your main code here, to run repeatedly:
}
如果我运行这段代码,我将从Wifi.status()
输出6,一旦我也得到4。4和6代表什么?是否连接?我还需要知道哪些其他状态代码?

输入 google "Arduino esp8266 source github" 你可能会找到 https://github.com/esp8266/Arduino . From there you can ex. type WL_CONNECTED
in search bar above and find this line of code:
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_WRONG_PASSWORD = 6,
WL_DISCONNECTED = 7
} wl_status_t;
