.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility looks for information about Bluetooth hosts and
|
|
Protocol Service Multiplexor (PSM) values.
|
|
It gets this information from the
|
|
.Pa /etc/bluetooth/hosts
|
|
and
|
|
.Pa /etc/bluetooth/protocols
|
|
files.
|
|
.Pp
|
|
In host mode, it simply converts between the host names and Bluetooth addresses.
|
|
The argument can be either a host name or a Bluetooth address.
|
|
The program first attempts to interpret it as a Bluetooth address.
|
|
If this fails, it will treat it as a host name.
|
|
A Bluetooth address consists of six hex bytes separated by a colon,
|
|
e.g.,
|
|
.Dq Li 01:02:03:04:05:06 .
|
|
A host name consists of names separated by dots, e.g.,
|
|
.Dq Li my.cell.phone .
|
|
.Pp
|
|
In protocol mode, it simply converts between the Protocol Service Multiplexor
|
|
names and assigned numbers.
|
|
The argument can be either a Protocol Service Multiplexor name or
|
|
an assigned number.
|
|
The program first attempts to interpret it as an assigned number.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl b
|
|
Produce brief output.
|
|
.It Fl h
|
|
Display usage message and exit.
|
|
.It Fl p
|
|
Activate protocol mode.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility will print results to the standard output, and error messages to the
|
|
standard error.
|
|
An output can be quite different,
|
|
here is an example that demonstrates all of the possibilities:
|
|
.Bd -literal -offset indent
|
|
% bthost localhost
|
|
Host localhost has address FF:FF:FF:00:00:00
|
|
% bthost ff:ff:ff:00:00:00
|
|
Host FF:FF:FF:00:00:00 has name localhost
|
|
% bthost -b localhost
|
|
FF:FF:FF:00:00:00
|
|
% bthost -b ff:ff:ff:00:00:00
|
|
localhost
|
|
% bthost do.not.exists
|
|
do.not.exists: Unknown host
|
|
% bthost 0:0:0:0:0:0
|
|
00:00:00:00:00:00: Unknown host
|
|
% bthost -p sdp
|
|
Protocol/Service Multiplexor sdp has number 1
|
|
% bthost -p 3
|
|
Protocol/Service Multiplexor rfcomm has number 3
|
|
% bthost -bp HID-Control

|
|
% bthost -p foo
|
