BTHOST(1)		  BSD General Commands Manual		     BTHOST(1)

NAME
     bthost — look up Bluetooth host names and Protocol Service Multiplexor
     values

SYNOPSIS
     bthost [-bhp] host_or_protocol

DESCRIPTION
     The bthost utility looks for information about Bluetooth hosts and Proto‐
     col Service Multiplexor (PSM) values.  It gets this information from the
     /etc/bluetooth/hosts and /etc/bluetooth/protocols files.

     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.,
     “01:02:03:04:05:06”.  A host name consists of names separated by dots,
     e.g., “my.cell.phone”.

     In protocol mode, it simply converts between the Protocol Service Multi‐
     plexor 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.

     The options are as follows:

     -b	     Produce brief output.

     -h	     Display usage message and exit.

     -p	     Activate protocol mode.

     The bthost 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:

	   % 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
	   17
	   % bthost -p foo
	   foo: Unknown Protocol/Service Multiplexor

FILES
     /etc/bluetooth/hosts
     /etc/bluetooth/protocols

EXIT STATUS
     The bthost utility exits 0 on success, and >0 if an error occurs.
