如何连接 iFrog LoRa 到 QNAP QIoT Suite Lite?－觀察筆記

本文章您将会学到如何透过 iFrogLab LoRa 将讯息传送到 QNAP QIoT Suite Lite.

事先准备

设定 iFrogLab LoRa USB 到 QIoT Suite Lite 以及 iFrogLab LoRa Gateway Container. 设定步骤请参考: http://www.ifroglab.com/en/?p=6613 (如果步骤10 一直没出现装置名称，可能是 TTY 到USB 的模块尚未加载，请尝试用 SSH 进入 NAS 并输入下列命令:

insmod /usr/local/modules/cdc-acm.ko
insmod /usr/local/modules/cp210x.ko
insmod /usr/local/modules/ftdi_sio.ko )

如果NAS 重新启动，则需重新输入以上命令。

设定 iFrogLab LoRa Gateway MQTT

请先建立 IoT 应用以及IoT 装置，并取得json (请参考: 如何将 DHT11 温湿度传感器的数据呈现在 QIoT 的 Dashboard? )

打开 Container Station，选择您的iFrog Lora Gateway并点选 "终端机".

1. 输入命令:
```
nano /ifroglab/IL-LORA1272/LoRa-Gateway/Gateway/Python/ap-01-lora-gateway-2-read-httpGet.py"
```
  并点选 "确认".
2. 光标移动到下列指令，并在前面加上 "#". 如下:
```
"mqtt=" mosquitto_pub -d -t ifroglab/mqtt -m '%s' -h test.mosquitto.org"%(HexString);"
```

3. 新增字符串:-h : 填入QIoT Suite Lite 服务的IP (若QIoT Suite Lite与iFrogLab LoRa Gateway在同一台，请填入Container Station内建NAT的Gateway IP 预设为: 10.0.3.1)[gallery columns="1" size="full" ids="2493"]
  
  -p : 预设21883，请依照resourceinfo.json信息进行填入
  -t : (topic) 请依照resourceinfo.json信息进行填入
  -u : (使用者名称) 请依照resourceinfo.json信息进行填入
  -P : (密码) 请依照resourceinfo.json信息进行填入
  -m : (讯息格式) 请依照范例填入即可
