SenseCAP T1000をHeliumに接続
デバイス設定
Heliumに接続する前に、SenseCAP Mate APPでデバイスの基本パラメータを設定する必要があります。詳細についてはGet Startedを確認してください。
- プラットフォームを
Heliumに設定し、Device EUI/APP EUI/APP Keyをコピーします。
Heliumコンソール設定
Heliumコンソールは新規アカウントの受付を終了しています。T1000をHeliumコンソールに接続する方法の説明は、既にアカウントを持つユーザー向けにここに残されています。新規ユーザーは、上記のChirpStack LNAの手順を参照するか、ここにある2つの既存の例に基づいて、特定のLNAに必要な手順を決定してください。
新しいデバイスの追加
Heliumコンソールにログインし、Devicesセクションに移動してAdd deviceボタンをクリックします。
デバイス名**、LoRaWAN認証情報などの必要なフィールドを入力します。
次にSave Device**ボタンをクリックします。
デコーダー関数の作成
次のステップは、生のバイトを人間が読める形式にデコードする関数を設定することです。
左側のパネルのFunctionタブに移動します。次にAdd New Functionボタンをクリックして名前を付けます：
以下のコードをコピーして変更を保存します。

データの確認
デバイスがネットワークに接続しようとすると、呼吸ライトが点滅します。デバイスがネットワークに正常に参加すると、呼吸ライトが素早く点滅し、軽やかで陽気なメロディーが鳴ります。
その後、Heliumコンソールでデータを確認できます。
注意事項
note
EU868/RU864地域で動作するユーザーの場合：
アップロード間隔を4分未満に設定することは推奨されません。
アップロード間隔を4分未満に設定すると、デバイスのアップリンクと現在時刻の間でタイムスタンプの不整合が発生する可能性があります。
理由は以下の通りです：
EU868における1%デューティサイクル制約により、デバイスは各アップリンク送信に対して約4分間辛抱強く待機する必要があります。さらに、HeliumネットワークはADRビットが1に設定された20個の連続したアップリンクパケットを蓄積した後にのみ、データレートと電力補正を開始します。
そのため、設定したアップロード間隔が4分未満の場合、リアルタイムデータは一時的にRAMに保存され、Heliumネットワークがデータレートと電力補正をトリガーするまで保持されてからアップロードされます。
ChirpStack LNS
新規ユーザーの場合、Heliumネットワーク上のデバイスからデータを受信するには、LNS（LoraWANネットワークサーバー）に関連付ける必要があります。通常はパブリックLNSの1つを使用し、その多くはChirpStackを使用していますが、独自のLNSをHeliumに接続することも可能です。
一般的なプロセスに精通している方向けのTL;DR;は以下の通りです：
- 適切な地域とコーデック（以下のソースを参照）でデバイスプロファイルを作成
devEUI、appKey、およびAppEUIを含むapp_eui変数でデバイスを作成。これら3つの値はすべてSenseCraftアプリから取得
デバイスプロファイルの追加
最初のステップは、T1000 TrackerのデバイスプロファイルをChirpStack LNSに追加することです。 これにより、LNSはT1000から受信したパケットをデコードする方法と、その他の多くの設定を認識します。
ChirpStackダッシュボードでDevice Profilesを選択し、Add device profileをクリックします。
一般タブで、認識できるデバイスプロファイル名を入力し、適切な地域パラメータを選択します。
LoRaWAN MACバージョン：1.0.4
予想されるアップリンク間隔も設定できます。これが主に制御するのは、LNSユーザーインターフェースでデバイスがアクティブ対非アクティブとして表示されるタイミングです。LNSを通じたパケット配信には影響しません。
コーデックタブでJavaScript functionsを選択し、コーデックを入力します：
tip
アプリケーションとデバイスの追加
次のステップは、アプリケーションを作成し、実際のデバイスを追加することです。
Applicationsセクションに移動し、新しいアプリケーションを追加します。
次に、アプリケーションにデバイスを追加し、先ほどSenseCraftアプリで取得したdevEUIを入力します。
変数タブで、SenseCraftアプリのAppEUIを値として持つapp_euiという変数を追加します：
送信をクリックすると、AppKeyを求めるページが表示されます。これも先ほどSenseCraftアプリを使用して取得したものです：
デバイス接続の確認
LoRaWAN framesタブでスピナーが表示され、パケットが受信/送信されると表示されます。
T1000 Trackerのボタンを押して測定を実行し、LNSに接続するためのjoin requestを送信します。
これが発生すると、次のような画面が表示されるはずです：
参加プロセスが実行されると、T1000はデータを送信します。LNSはネットワーク周波数などに関する情報を返しますが、その後はデータを含むアップリンクのみが存在するはずです。
