求助关于蓝牙的问题

这两天/dev下的hci0设备文件突然不见了，hciconfig、hcitool等命令也消失了，前几天还在，不知道是什么原因。
附上dmsg有关蓝牙的信息：

hciconfig、hcitool这些命令是哪个软件包里的？

没有软件包包含 hciconfig, hcitool：

~$ pkgfile -b hciconfig
~$ pkgfile -b hcitool
~$

我创建了一个BCM.hcd的符号链接，现在已经可以使用蓝牙了，只是/dev下的hci0文件以及系统命令hciconfig,hcitool等还是没有，这是什么原因？

还有两个问题：
1、用蓝牙无法向手机传送程序文件，但可以传送其他文件如文档文件和动态库文件；
2、系统睡眠又唤醒后，蓝牙无法使用了。
以下是一些信息：

刚刚我尝试了一下给程序文件加上后缀.exe结果蓝牙可以正常传送到手机了。只能传输带点号的文件，这属于gnome的bluetooth-sendto的一个bug吗？

刚在Reddit上找到了一个讨论
说是这几个命令已经被 deprecated 。。。
所以只用 bluetoothctl 就好
