前回の反省
- ステータス反映時にESVをチェックしていなかったためEDTがない場合(ESV0x71など）に挙動がおかしかった
ESV0x72(プロパティ値読み出し応答)0x73(プロパティ値通知)をチェック
- 設定値の確認をしていなった
tidをflowコンストラクタで設定して戻りのESV0x71で同一tidであることを確認(本来はGet0x62で確認推奨）
同一tidとなるまでwait0.2secをかけてループ(本来は20sec空ける必要あり）
- 並列処理ができないことを考慮せず
さらなる反省点・感想
ESV0x72(プロパティ値読み出し応答)0x73(プロパティ値通知)をチェック
tidをflowコンストラクタで設定して戻りのESV0x71で同一tidであることを確認(本来はGet0x62で確認推奨）
同一tidとなるまでwait0.2secをかけてループ(本来は20sec空ける必要あり）
最初から規格書(pdf)を読んでいればおかしな挙動はなかった。panasonic謹製アプリでもエラーとなることから無線アダプタでの処理には時間がかかる模様。
