Debian 11をインストールしましたが、Bluetoothが機能しません。
コマンドを実行すると、sudo systemctl status bluetoothBluetoothがアクティブになって表示されます。ただし、構成に入ると、次のようになります。
ポルトガル語のメッセージは次のとおりです。 「Bluetoothが見つかりません。」 [![ここに画像説明を入力][1]][1]

WiFiファームウェアをインストールしましたが、AR9565用のフルBluetoothファームウェアはありません。
再起動する必要がありますsudo apt install firmware-atheros。
