BACnet Tools are binary demo application command line
utilities that use BACnet/IP to perform a variety of
BACnet services. Some tools use BACnet WhoIs to bind to
devices, but can also use a static binding file address_cache.

Most of the tools have help (--help option), and use
environment variables to configure the datalink.

The Client Tools use WhoIs to bind to target devices.
The WhoIs can be eliminated by using the address_cache
file, which is read by each client tool from the current
working directory.  Having the device address from the
address_cache file will greatly improve the throughput
and speed of the client tools. The address_cache file
can be generated using the standard output of the bacwi tool.

EXAMPLE:
bacwi -1 > address_cache

MS/TP Capture Tool
------------------
The mstpcap tool is used for capturing MS/TP traffic
from an RS-485 serial adapter and saving the packets
in a file for viewing by Wireshark.

Environment Variables
---------------------
BACNET_APDU_TIMEOUT - set this value in milliseconds to change
    the APDU timeout.  APDU Timeout is how much time a client
    waits for a response from a BACnet device. Default is 3000ms.

BACNET_IFACE - set this value to dotted IP address (Windows) of
    the interface (see ipconfig command on Windows) for which you
    want to bind.  On Linux, set this to the /dev interface
    (i.e. eth0, arc0).  Default is eth0 on Linux, and the default
    interface on Windows.  Hence, if there is only a single network
    interface on Windows, the applications will choose it, and this
    setting will not be needed.

BACNET_IP_PORT - UDP/IP port number (0..65534) used for BACnet/IP
    communications.  Default is 47808 (0xBAC0).

BACNET_BBMD_PORT - UDP/IP port number (0..65534) used for Foreign
    Device Registration.  Defaults to 47808 (0xBAC0).

BACNET_BBMD_TIMETOLIVE - number of seconds used in Foreign Device
    Registration (0..65535). Defaults to 60000 seconds.

BACNET_BBMD_ADDRESS - dotted IPv4 address of the BBMD or Foreign Device
    Registrar.

Example Usage
-------------
You can communicate with the virtual BACnet Device by using the other BACnet
command line tools.  If you are using the same PC, you can use BBMD/FD
(Foreign Device registration) to do this - use the bvlc script.  You can
monitor the interaction and bytes on the wire using Wireshark.  Here is 
an example usage for Window and for Linux.

Windows
-------
The BACnet tools are used from the Command Prompt, or CMD.EXE.  
From the command prompt window, start the simulated BACnet device:
c:\> bacserv 1234

From another command prompt window, use ipconfig to determine the 
network interface IP address that bacserv is using: 
c:\> ipconfig

Use the default IP address to configure the BBMD and Foreign Device
environment variables:
c:\> bvlc.bat 192.168.0.42

bvlc.bat batch file configures environment variables to use BACnet/IP 
port 47809 for any subsequent BACnet tools run from that command prompt window, 
and enables the BBMD Foreign Device Registration.

Perform a device discovery:
c:\> bacwi -1

Read all the required properties from the Device 1234 and display their values:
c:\> bacepics -v 1234

Read the Object_Identifier property from the Device 1234:
c:\> bacrp 1234 8 1234 75

Write 100.0 (REAL=4 datatype) to Device 1234 Analog Output (1) One (1) 
at priority 16 with no index (-1).
c:\> bacwp 1234 1 1 85 16 -1 4 100.0

Each tool has help:
c:\> bacrp --help

Linux
-----
To use the tools from the command line, you need to use the path to the command,
or include the path in your PATH environment variable.  The dot "." means current
directory.  The "/" is used to separate directories. "./" means the path starts
from the current directory.

When the tools are built from the Makefile, they are copied to the bin/ directory.
So from the root of the project you could run the tools like this using a terminal
window:
$ make clean all
$ ./bin/bacserv 1234

In another terminal window use ifconfig to determine the network interface IP 
address that bacserv is using: 
$ ifconfig

Use that address (likely from eth0) to configure the BBMD and Foreign Device
environment variables:
$./bin/bvlc.sh 192.168.0.42
bvlc.sh script configures environment variables to use BACnet/IP 
port 47809 for any subsequent BACnet tools run from that shell, 
and enables the BBMD Foreign Device Registration.

Perform a device discovery:
$ ./bin/bacwi -1

Read all the required properties from the Device 1234 and display their values:
$ ./bin/bacepics -v 1234

Read the Object_Identifier property from the Device 1234:
$ ./bin/bacrp 1234 8 1234 75

Write 100.0 (REAL=4 datatype) to Device 1234 Analog Output (1) One (1) 
at priority 16 with no index (-1).
$ ./bin/bacwp 1234 1 1 85 16 -1 4 100.0

Each tool has help:
$ ./bin/bacrp --help
