.Op Fl hN
.Op Fl n Ar HCI_node_name
.Ar command
.Op Ar parameters ...
.Sh DESCRIPTION
The
.Nm
utility connects to the specified Netgraph node of type
.Dv HCI
or the first one found if none is specified and attempts to send the specified
command to the HCI Netgraph node or to the associated Bluetooth device.
The
.Nm
utility will print results to the standard output and error messages to
the standard error.
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl h
Display usage message and exit.
.It Fl N
Show Bluetooth addresses as numbers.
Normally
.Nm
attempts to resolve Bluetooth addresses, and display them symbolically.
.It Fl n Ar HCI_node_name
Connect to the specified HCI Netgraph node.
.It Ar command
One of the supported commands (see below).
The special command
.Cm help
can be used to obtain the list of all supported commands.
To get more information about a specific command use
.Cm help Ar command .
.It Ar parameters
