Broadcom DW1560蓝牙Airdrop的问题

升级到Monterey之后DW1560可以用Bluetoolfixup 2.6.1驱动，但是AirDrop只能收，无法发送给iPhone/iPad。目前我找到了一个临时的解决方案，需要用两个iOS设备，一个在发送的时候，文件会被卡住，但是在这个时候用另外一个设备扫描airdrop，被卡住的文件就可以正常被发送出来。

我看了看log，在airdrop卡住的时候：

而当airdrop能正常发送的时候：

貌似这个问题存在于这个参数fScanFiltersNeedUpdating，不知道哪位大神可以hack一下这个参数，绕过filter update？或许可以解决这个问题。
