btmonピアから送信/受信したBluetoothパケットを監視するために使用します。btmonUbuntuシステムでこのコマンドを実行すると、以下の説明に従ってログが収集されます。私も次のマニュアルページを読みました。https://manpages.debian.org/testing/bluez/btmon.1.en.html
どのパケットが送信パケットと見なされ、どのパケットがすべてのデータ受信と見なされるかを知る必要があります。
ログにTxとRxが記載されており、時間も言及されていることを観察しましたが、パケットの送信が始まる場所とパケットの受信が終わる場所はわかりません。
基本的に、ピアがパケットを送信した後にどれくらい時間がかかるかを知りたいです。

誰かが私にbtmonログ形式を説明して必要なものを得ることができますか？フォーマットはどこに文書化されていますか？
ベストアンサー1
man btmonbtsnoop形式で教えてください。
