skargThere are a dozen or so demo applications that are built with the default makefiles. These demo applications are copied to the bin/ directory. They can be used in scripts and batch files to test BACnet devices or query information on the BACnet network, as well as simulate a BACnet device. The demo applications make use of Environment Variables to configure the network. BACNET_IFACE - interface to use for the datalink layer For Linux, this is something like eth0 or /dev/ttyS0. For Windows, this is something like 192.168.0.1 or COM4 Defaults to NULL. BACNET_IP_PORT - BACnet/IP port number. Defaults to 47808. BACNET_BBMD_PORT - BACnet/IP BBMD port number. Defaults to 47808. BACNET_BBMD_TIMETOLIVE - BACnet/IP BBMD time-to-live seconds. Defaults to 0xFFFF. BACNET_BBMD_ADDRESS - dotted IP address or domain name of BBMD. Attempts to register with the BBMD if this variable is present. BACNET_MAX_INFO_FRAMES - BACnet MS/TP max-info-frames parameter. Defaults to 127. BACNET_MSTP_BAUD - BACnet MS/TP baud rate. Defaults to 38400. BACNET_MSTP_MAC - BACnet MS/TP MAC address. Defaults to 127. The demo client applications can also perform static address binding using the file "address_cache" in the directory where the application is called (defined in src/address.c file). The format of the address_cache is a line by line of device ids and addresses: 55555 AC:10:56:06:BA:C0 26001 19 50 where: 55555=device id in decimal AC:10:56:06:BA:C0=MAC address (router address) in hex 26001=DNET network number in decimal 19=DADR MAC address in hex. Use colon to separate multibyte address. 50=Max APDU
