我已经安装了几个蓝牙包：
sudo apt-get install bluetooth bluez bluez-tools rfkill
然后尝试服务BT：
$sudo bt-obex -s /NAS/media/ScanInbox
bt-obex: obex service is not found
Did you forget to run obexd?
我所说的安装
sudo apt install obexd-server
它安装了许多 Unity 和 Gnome 软件包，尽管我的机器是无头的，我可能不需要它。
之后我还是不能
$ sudo service obex start
obex: unrecognized service
$ sudo service obexd start
obexd: unrecognized service
$ sudo service obexd-server start
obexd-server: unrecognized service
$ sudo service obexd-service start
obexd-service: unrecognized service
$ sudo bt-obex -s /NAS/media/ScanInbox
bt-obex: obex service is not found
Did you forget to run obexd?
如何实现？没有任何名称像 obex 的服务。安装程序obex-server做了什么？
