大家好
我想請問關於 ESP-WROOM-02 連不到WIFI了話哪裡有問題??
以下為我的程式和線路圖

#include "ESP8266.h"
#include "Milkcocoa.h"
#include "Client_ESP8266.h"

// 傳輸率
#define SERIAL_SPEED       115200

/************************* WiFi Access Point *********************************/

// Wi-Fi SSID
#define WLAN_SSID  "pcsetting-wifitest"
// Wi-Fi PASSWORD
#define WLAN_PASS  "jetproinc"

// Milkcocoa的APP ID
#define MILKCOCOA_APP_ID "onj3v4c9jn"
// Data Store名稱
#define MILKCOCOA_DATASTORE "sensor"

#define MILKCOCOA_SERVERPORT  1883

// Create an ESP8266Client class to connect to the MQTT server.
ESP8266Client wifi;

const char MQTT_SERVER[] PROGMEM = MILKCOCOA_APP_ID ".mlkcca.com";
const char MQTT_CLIENTID[] PROGMEM  = __TIME__ MILKCOCOA_APP_ID;

Milkcocoa milkcocoa = Milkcocoa(&wifi, MQTT_SERVER, MILKCOCOA_SERVERPORT, MILKCOCOA_APP_ID, MQTT_CLIENTID);

// 跟感測器接在一起的腳
const int sensorPin = A0;

void setup() {
  // 開啟跟電腦之間序列通信的埠
  Serial.begin(SERIAL_SPEED);
  // 開啟跟Wi-Fi模組之間序列通信的埠
  Serial5.begin(SERIAL_SPEED);

  // Wi-Fi設定
  setupWiFi();
}

/*
  設定Wi-Fi
*/
void setupWiFi() {
  Serial.print("Connecting to ");
  Serial.println(WLAN_SSID);

  // 指定序列埠
  wifi.begin(Serial5);

  // 連接Wi-Fi(重複處理直到連接成功)
  while (!wifi.joinAP(WLAN_SSID, WLAN_PASS)) {
delay(500);
Serial.print(".*.");
  }

  Serial.println("Wi-Fi connected");
  Serial.println("IP address: ");
  // 把Wi-Fi的local IP位置顯示在序列埠監控視窗上
  Serial.println(wifi.getLocalIP().c_str());
}

void loop() {
  // 執行Milkcocoa的loop處理
  milkcocoa.loop();

  // 感測器的值
  int sensorValue = analogRead(sensorPin);

  Serial.print("Sensor Value : ");
  Serial.println(sensorValue);

  // 做成傳送給Milkcocoa的資料
  DataElement elem = DataElement();
  // 以sensorValue這個資料名稱來追加值
  elem.setValue("sensorValue", sensorValue);
  // 送資料到Milkcocoa
  milkcocoa.send(MILKCOCOA_DATASTORE, &elem);
}
