bthost -- look up Bluetooth host names and Protocol Service Multiplexor
bthost [-bhp] host_or_protocol
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 host names and Bluetooth
addresses. The argument can be either host name or Bluetooth address.
The program first attempts to interpret it as Bluetooth address. If this
fails, it will treat it as host name. A Bluetooth address consists of
six hex bytes sparated by column, 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 Protocol Service Multiplexor
names and assigned numbers. The argument can be either Protocol Service
Multiplexor name or assigned number. The program first attempts to
interpret it as 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. You may see output of different kinds.
Here is an example that shows all of them:
% 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.
