SenseCAP decoderは、SenseCAP LoRaWAN®デバイスから送信されるLoRaWANメッセージをデコードするために使用されます。デコード後、ユーザーのアプリケーションはより親しみやすく、読みやすいメッセージを取得できます。
SenseCAP T1000 Tracker
SenseCAP T1000は、GNSS/Wi-Fi/Bluetoothを利用して屋内外の精密な位置追跡を行うコンパクトなLoRaWAN®トラッカーです。自己地理適応機能、ローカルデータストレージ、そして数ヶ月間のバッテリー寿命を誇ります。さらに、温度、光、モーションセンサーを搭載しており、様々な位置ベースアプリケーションに最適です。

使用方法
準備
デコーダーを設定する前に、製品マニュアルに従ってセンサーとゲートウェイを正しく設定し、必要なLoRaWANネットワークサーバーに接続してください。
The Things Stackを例として、以下の手順でデコーダーを設定してください：
ペイロードデコーダーの設定
- デバイスの
Payload Formatsタブに移動します。 Payload FormatでCustomを選択します。decoder.jsの全内容をコピーしてdecoderテキストエリアに貼り付けます。save payload functionsをクリックします。
デコードされたメッセージの確認
まず、サンプルペイロードでデコードスクリプトをテストできます。
これを行うには、01 01 10 98 53 00 00 01 02 10 A8 7A 00 00 AF 51のような生データパケットをPayloadテキスト入力にコピーし、デバイスマニュアルに従ってFPortを選択し、Testボタンをクリックします。以下に正常に解析されたJSON構造が表示されます。
次に、スクリプトの魔法を確認しましょう。Live Dataタブに移動し、アップロードされたメッセージを展開してペイロード内のEvent Fieldsを確認できます。これらのフィールドはスクリプトによって生成されたものです。
TTNのMQTT Data APIでメッセージを購読している場合、解析されたJSONペイロードフィールドも取得できます。
