私の車のデータを読み取ろうとするのに安いelm327 bt obd2コネクタを接続し、lubuntuを使用しました。
基本的にはこれをしましたが、うまく機能しなかったので、最終的には一度に1人のチャーターだけが見ることができ、応答のないバギーターミナルになりました。
まずペアリングして信頼します。

次に、rfcommを使用してシリアル接続を確立し、sdptoolを実行してどのチャネルに存在するかを確認し、次を実行します。

画面接続を使用すると機能しているように見えますが、1文字しか表示されません。
user@user-20n20009pg:~$ sudo screen /dev/rfcomm0 38400
その後、別の端末で開き、次のことが行われます。

完全なatzコマンドを作成できないようです。一度に1文字しか表示されません。
私が何を逃したのか知っていますか？
