链接 mqtt 失败 connecting to MQTT... Connectting failed

本帖最后由 hudcan 于 2022-8-22 09:36 编辑

各位大佬请求一个问题,我想用 esp32 控制电脑开机参考的这篇文章(https://post.smzdm.com/p/aoown0g7/),

这个代码我去年也是用的这个，当时是正常运行的，昨天想改一下，发现原来的代码也运行不了了，不知道是不是哪里有什么问题？

但是烧录后报这个错,请问是啥原因?

代码如下：
/**********************************************
* ESP32 + ARDUINO + Blinker + XiaoAi
* Remote boot by WOL
* Creater：Faiz
*/

#define BLINKER_WIFI
#define BLINKER_MIOT_OUTLET

#include <Blinker.h>
#include <WiFiUdp.h>
#include <WiFi.h>
char auth[] = "xxxxxxxxxx"; //密钥
char ssid[] = "Faiz"; //wifi名
char pswd[] = "xxxxxxxx"; //wifi密码

//The udp library class
WiFiUDP udp;

bool oState = false;
BlinkerButton Button1("awaking");

//awaking！
void button1_callback(const String & state)
{
BLINKER_LOG("get button state: ", state);
digitalWrite(LED_BUILTIN, HIGH);
delay(50);
digitalWrite(LED_BUILTIN,LOW);
delay(50);
pcawaking();
digitalWrite(LED_BUILTIN, HIGH);
delay(50);
digitalWrite(LED_BUILTIN, LOW);
delay(50);
digitalWrite(LED_BUILTIN, HIGH);
delay(50);
digitalWrite(LED_BUILTIN, LOW);
delay(50);
}

void miotPowerState(const String & state)
{
BLINKER_LOG("need set power state: ", state);

if (state == BLINKER_CMD_ON) {
   BlinkerMIOT.powerState("on");
   BlinkerMIOT.print();
      digitalWrite(LED_BUILTIN, HIGH);
      delay(25);
      digitalWrite(LED_BUILTIN, LOW);
      delay(25);
      pcawaking();
      digitalWrite(LED_BUILTIN, HIGH);
      delay(25);
      digitalWrite(LED_BUILTIN, LOW);
      delay(25);
      digitalWrite(LED_BUILTIN, HIGH);
      delay(25);
      digitalWrite(LED_BUILTIN, LOW);
      oState = false;//force off！！
}
else if (state == BLINKER_CMD_OFF) {
   digitalWrite(LED_BUILTIN, LOW);

   BlinkerMIOT.powerState("off");
   BlinkerMIOT.print();

   oState = false;
}
}

void miotQuery(int32_t queryCode)
{

switch (queryCode)
{
   case BLINKER_CMD_QUERY_ALL_NUMBER :
         BLINKER_LOG("MIOT Query All");
         BlinkerMIOT.powerState(oState ? "on" : "off");
         BlinkerMIOT.print();
         break;
   case BLINKER_CMD_QUERY_POWERSTATE_NUMBER :
         BLINKER_LOG("MIOT Query Power State");
         BlinkerMIOT.powerState(oState ? "on" : "off");
         BlinkerMIOT.print();
         break;
   default :
         BlinkerMIOT.powerState(oState ? "on" : "off");
         BlinkerMIOT.print();
         break;

}
   digitalWrite(LED_BUILTIN, HIGH);
   delay(25);
   digitalWrite(LED_BUILTIN, LOW);
   delay(25);
   digitalWrite(LED_BUILTIN, HIGH);

能不能具体一点呢，我只把 GitHub 的 blinker-library 放到了指定的目录，不知道你说的依赖指的是？
