MQTT_RFID 中的 PubSubClient 程式庫安裝問題

MQTT_RFID 中的 PubSubClient 程式庫安裝問題

MQTT_RFID_2 中的 PubSubClient 程式庫安裝問題

我的Arduino 版本是1.6.5

有關 pubsubclient.h 問題        (PubSubClient Version 2.6.0版本)

1)    若是已經安裝者pubsubclient 程式庫者 請將 C:\Users\使用者\Documents\Arduino\libraries 中的目錄 pubsubclient刪除

2)    將pubsunclient-master解壓縮後 整個目錄 copy 到 C:\Users\使用者\Documents\Arduino\libraries 中的目錄。

3)    打開Arduino 組譯 是否有錯誤  ???

  // Once connected, publish an announcement...

  client.publish("alex9ufo/outTopic/RFID/json", jsonChar, MQTTpubQos, true); // true means retain

  // ... and resubscribe

  client.subscribe("alex9ufo/inTopic", MQTTsubQos);

4)    沒有錯誤代表PubSubClient.h 程式庫正確
