NAME

bthost – look up Bluetooth host names and Protocol Service Multiplexor values

CONTENTS

SYNOPSIS


bthost [-bhp] host_or_protocol

DESCRIPTION

The bthost utility looks for information about Bluetooth hosts and Protocol 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 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.

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

"I liken starting one's computing career with Unix, say as an undergraduate, to being born in East Africa. It is intolerably hot, your body is covered with lice and flies, you are malnourished and you suffer from numerous curable diseases. But, as far as young East Africans can tell, this is simply the natural condition and they live within it. By the time they find out differently, it is too late. They already think that the writing of shell scripts is a natural act."
