bluetoothctl报下面的错误 ,没有scan on这命令
Waiting to connect to bluetoothd...dbus[6308]: arguments to dbus_connection_get_object_path_data() were incorrect, assertion "connection != NULL" failed in file dbus-connection.c line 59.
This is normally a bug in some application using the D-Bus library.
D-Bus not compiled with backtrace support so unable to print a backtrace
