BTHOST(1) BSD General Commands Manual BTHOST(1)NAMEbthost — look up Bluetooth host names and Protocol Service Multiplexor
SYNOPSISbthost [-bhp] host_or_protocol
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,
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
% bthost-b ff:ff:ff:00:00:00
% 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
foo: Unknown Protocol/Service Multiplexor
The bthost utility exits 0 on success, and >0 if an error occurs.
