look up Bluetooth host names and Protocol Service
utility looks for information
about Bluetooth hosts and Protocol Service Multiplexor (PSM) values. It gets
this information from the
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.,
”. A host name
consists of names separated by dots, e.g.,
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:
- Produce brief output.
- Display usage message and exit.
- Activate protocol mode.
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
% 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
utility exits 0 on success,
and >0 if an error occurs.
