USB_Host_Shield_2.0とBlueToothドングルを用いたArduinoとPS4互換コントローラーの接続

前提・実現したいこと

Arduino MEGAとDUALSHOCK4互換のコントローラーをBlueToothドングルとUSB_Host_Shield_2.0のPS4BT.inoを用いて接続したいです．

発生している問題・エラーメッセージ

PS4BT.inoをBlueToothドングルを差し込んだArduinoに書き込んだのち，コントローラーのSHAREボタンとPSボタンを同時押しして初期接続モードに入り，シリアルモニタを確認したところ以下のようにメッセージが出ます．
しかしコントローラーは初期接続に失敗し(ずっと点滅したままで点灯にならない)，ボタンを押しても何一つ反応がありません．

あるサイトからお借りした画像ですが，自分の環境ではSend HID Control Request以下に続くはずのメッセージが表示されていません．

該当のソースコード

PS4BT.inoのスケッチになります．(gitからダウンロードしたままのものです．)
PS4BT.hやPS4Parser.cpp, PS4Parser.h辺りを書き換える必要があるのかなと考えていますが，それがあってるのかもよくわかりません．
