如何連接 iFrog LoRa 到 QNAP QIoT Suite Lite?－觀察筆記

本文章您將會學到如何透過 iFrogLab LoRa 將訊息傳送到 QNAP QIoT Suite Lite.

事先準備

設定 iFrogLab LoRa USB 到 QIoT Suite Lite 以及 iFrogLab LoRa Gateway Container. 設定步驟請參考: http://www.ifroglab.com/en/?p=6613
(如果步驟10 一直沒出現裝置名稱，可能是 TTY 到USB 的模組尚未載入，請嘗試用 SSH 進入 NAS 並輸入下列命令:
insmod /usr/local/modules/cdc-acm.ko
insmod /usr/local/modules/cp210x.ko
insmod /usr/local/modules/ftdi_sio.ko )

如果NAS 重新開機，則需重新輸入以上命令。

設定 iFrogLab LoRa Gateway MQTT

請先建立 IoT 應用以及IoT 裝置，並取得json (請參考: 如何將 DHT11 溫濕度感測器的資料呈現在 QIoT 的 Dashboard? )[gallery columns="1" size="full" ids="2466"]

打開 Container Station，選擇您的iFrog Lora Gateway並點選 "終端機".[gallery columns="1" size="full" ids="2467"]

輸入命令:

nano /ifroglab/IL-LORA1272/LoRa-Gateway/Gateway/Python/ap-01-lora-gateway-2-read-httpGet.py"

並點選 "確認".

游標移動到下列指令
```
"mqtt=" mosquitto_pub -d -t ifroglab/mqtt -m '%s' -h test.mosquitto.org"%(HexString);"
```
並在前面加上 "#". 如下:

新增字串:[gallery columns="1" size="full" ids="2469"]

-h : 填入QIoT Suite Lite 服務的IP (若QIoT Suite Lite與iFrogLab LoRa Gateway在同一台，請填入Container Station內建NAT的Gateway IP 預設為: 10.0.3.1)

-p : 預設21883，請依照resourceinfo.json資訊進行填入

-t : (topic) 請依照resourceinfo.json資訊進行填入

-u : (使用者名稱) 請依照resourceinfo.json資訊進行填入

-P : (密碼) 請依照resourceinfo.json資訊進行填入

-m : (訊息格式) 請依照範例填入即可[gallery columns="1" size="full" ids="2471"]

按下 "Ctrl+O" 以及 "Enter" 保存並按下 "Crtl+X" 離開.[gallery columns="1" size="full" ids="2472"]

打開 "iFrogLora Gateway" 容器. 若出現以下畫面即為修改成功[gallery columns="1" size="full" ids="2473"]

切換到 "QIoT Suite Lite" > "IoT 應用". 點選 " IoT 裝置資料日誌" 即可看見資料傳入狀態[gallery columns="1" size="full" ids="2474"]

切換到 "規則"，即可開始設計您的IoT應用，接收到的資料為HEX。(可參考下列範例)[gallery columns="1" size="full" ids="2475"]
