this allows much easier testing on all platforms

some build systems normally take tags and not commits e.g. yocto build system, conan package manager

It would be great if we could make a e.g. patch release as now we have cmake support and can use this to be cross platform.

Compiling and linking the BACnet Stack library with other libraries
has been a challenge to me and others over the years due to header
name collisions, function naming collisions, file name collisions, and
argument name collisions. I have some ideas about fixing those, but it
will require some movement in the folder structure, file name changes,
and some include file name changes. I've become a big fan of the
Linnaeus naming convention, and have been working with other libraries
(Contiki, cryptoauthlib, mbedtls) that do a good job of handling file
and folder naming to avoid collisions (mostly!).

the two default I/O in the stm32 example dont appear to change actual physical pins when requested to set or clear its values. Which physical IOs are mapped to the ones recognized by the software? And how could one change those?

In existing pipelines, run the ztest-based unit tests.

Hi ! I'm wondering if I could have some help from you to build a C Extension from the stack to allow Python to use MSTP.

Speed and timers being at the core of MSTP, it's very hard (let say it won't be possible) to have MSTP working in pure Python... but it would be possible as a C extension.

My C knowledge is -2 on a scale of 0 to 10... but I could help with the Python part.

[ref] https://docs.python.org/3/extending/building.html

That would be a super nice add-on to our projects.

this issue shall track the status of the secure connect datalink implementation

Hello,

I've built the latest source from github on Ubuntu 16.04 and trying to connect to Legrand RCU (Bacnet enabled Room Control Unit).

Thanks

regarding ai object, is there a default range stated by the bacnet specification? like 0-100? or can it be just any float number? Im having an issue porting ai.c to the stm32 port, in which the max value being read by the ADC(around 4095 for the 12-bit ADC), is being read by the bacnet client as 5.7, and around half that(around 1.66V at the ADC input) is being read as 2.9~. Why is 4095~ integer being interpreted as 5.7? I know it's probably a type casting issue, but I can't figure it out. if there's an easy fix I'm not seeing, please help.

Dear Steve;

I still have troubles compiling Arduino_uno port. Did you know who was the developer of that part of the stack?

Regards

Adriano

In a standard zephyr build for an ARM target, the compiler errors out on calls passing &enumeration field to a function parameter requiring &uint32_t field.

Hello, I am looking to change the Cmakelists file slightly so it can build two separate shared libraries of the stack, one for IP and the other for MSTP. It would look something like this:

if(BACDL_BIP)
project(bacnet-ip VERSION 1.0.0 LANGUAGES C)
elseif(BACDL_MSTP)
project(bacnet-mstp VERSION 1.0.0 LANGUAGES C)
endif()

However, before even adding that, if I try change the existing project from:

project(bacnet-stack VERSION 1.0.0 LANGUAGES C)

to something slightly different:

project(bacnet-stack1 VERSION 1.0.0 LANGUAGES C)

When set to "bacnet-stack", the library produced works and is usable in my project. If set to "bacnet-stack1" though, the library is over 100 KB smaller and seems to be missing a lot of symbols and cannot be used with my project.

I am just wondering do you know if there is a way to get around this so the resultant stack library produced can be named something other than libbacnet-stack.so

currently we are only building for the three major OSs, linux, mac, win32.

there are no tests beiing executed.
If tests were executed with CI, we could also get test coverage reports etc.

Hi dear~

I want to handle request of CONFIRMED_ADD_LIST_ELEMENT, but the stack code seems not yet achieved it, just like the readprop demo does:
apdu_set_confirmed_handler(SERVICE_CONFIRMED_READ_PROPERTY, handler_read_property);

Is anyone trying even to run and build BACNET stack on FreeBSD 11/12 ? Under FreeBSD 11 64bit I cannot go far:

Questions:

• what is this prefix ? bacnet-stack-bacnet-stack-1.0.0 ? can't you fix the release properly to have bacnet-stack only ?
• any ideas about FreeBSD 11 compile errors ?

Cmake is the most used build system which is supported by most ides now (vscode, qtcreator, visual studio, clion, etc)

It is now also natively supported on windows with visual studio (open project and it works)

It would be great therefore to add cmaks support to this project
We could sponsor this feature

@skarg what do you think?

While compiling for Zephyr with PRINT_ENABLED false, the following warnings were reported. Each needs the auto variable definition to also be conditionally compiled.

make BACDL_DEFINE=-DBACDL_ALL=1 fail
make BACDL_ALL=1 fail

So how to make it support all the datalinks?

Inneasoft BACnet Explorer sends only 4 Bytes for getAlarmSummary: ADPU 02 75 2b 03
That leads to a crash because service_choice is NULL.

Fix: Replace line 334 in h_apdu.c if (apdu_len >= (len+2))
with

	if (apdu_len == (len + 1)) {
		*service_choice = apdu[len++];		// no request data as seen with Inneasoft BACnet Explorer

Hello,

I would like to compile bacnet for my ESP32. But I'm getting an error, that bacport.h is missing.
Where do I get this file?

Hello,

While helping to package this project at conan-io/conan-center-index#909, I noticed some problems with bacnet-stack.

• When building shared libraries using cmake, the build fails.
  I think this is because the linux build has not all files included.
• Also, some files use OpenSSL, but the cmake script does not look for it.
  It requires a find_package(OpenSSL) somewhere + use of the variables/targets.
• macos fails to build

Fixing these issues should also fix some potential problems with the static build.

Hello, are there any plans for higher levels of abstraction for your stack? Something like a communication object for client/server use with methods for reading/writing data or subscripe covs. Its really hard to start working with your stack. All demos work fine but there is no starting point for using the stack in own applications.

I get an error when I build a project ..\ports\esp32.
I have followed the readme.txt but failed
libraries/bacnet/bacnet/datalink/bip.h:26:21: fatal error: bacport.h: No such file or directory
Can Team help me?

Kindly share proper working steps to build ESP32 port.

I followed all steps mentioned in readme document but it fails to build.

It shows unable to find timer.h error in device.c file.

Many projects use codespell for this task. RIOT OS project provides a shell script for this task.

I guess there is no need to have visual studio project files anymore as visual studio works out of the box with cmake.

As cmake works on all platforms, its well supported by IDEs and recently also by package managers, I also suggest to make the default build system if possible.

Even if a different name is supplied on the command line as a parameter the device is always called "SimpleServer".

What should I do to get the communication working? My understanding is that this should work out of box, if compile was successful.
I have no clue what is the 4194303 device, only one Bacnet device is on the network.

Thanks

First of all, thank you for this library, great work :)
I'm trying to to communicate with a BMT-DO4. This is working fine when using an USB RS-485 dongle. But as soon as I try to use the native RS-485 port instead of the USB dongle, the communication fails (sending a bind request, but can never bind until it timeouts).
My understanding is that I would need to manually set the RTS pin high and low depending on when I'm transmitting or receiving a frame.
Where would be the best place to add such a change? As far as I know/understand, libmodbus did something similar as it can be seen here:
https://github.com/stephane/libmodbus/blob/master/src/modbus-rtu.c

west 0.8.0a1 supports specifying manifest files elsewhere in the tree. This introduces the config setting 'manifest.file config' and clarifies the meaning of the config 'manifest.path'. This requires updating how this repository uses manifest files.

To Do:

• Remove the top level west.yml
• Add self to the zephyr/modules/** manifest files
  ? Clean out ZEPHYR_EXTRA_MODULES if no longer needed.

The new range 47808-49999 is the problem. It returns "proprietary 47808" for an index of 47808 instead of standard-cubic-feet-per-day, for example.

When Zephyr Project resolves zephyrproject-rtos/zephyr#28438, update module to follow example interfacing pattern for out-of-tree modules.

Wondering if the CMakeLists.txt should be changed like so:

    ...
-   $<$<BOOL:${BACDL_MSTP}>:src/bacnet/datalink/mstp.h>
+   $<$<BOOL:${BACDL_MSTP}>:src/bacnet/datalink/mstp.c>
    src/bacnet/datalink/mstpdef.h
    src/bacnet/datalink/mstp.h
    ...

Currently if BACDL_MSTP is defined, the line will be the same as the one two lines down.

If so, I can create a PR.

I use Network_Port_Network_Number_Set(1, 49999) to set the network number as 49999 in bacserv sample app,
and then I use YABE to explore my sample bacserv, I can find the network number is 49999 in "OBJECT_NETWORK_PORT:1" of my simulated device.

But when I use "./bacwi --dnet 49999" to request bacnet device with network 49999, I can not find any device, only find device by "./bacwi --dnet 0".

Does any one can help me to know what wrong and guide me to correct it? Thanks a lot.

In the Zephyr environment, the struct sockaddr_in definition does not include explicit padding fields. This means the src/BACnet/datalink references to the sin_zero padding field are invalid for that environment, resulting in portability issues.

I'm developing my bacnet program base on the demo of router. The demo currently can only route message from this port to the other.
How can the router handle the App message incoming for itself?

I try to add some app handler, for example, "read property", "I-am", etc., on the demo, but it seems not appropriately to do this because it has to judge which port to request/ack the message and it works not quite well.
can Anybody give me some suggestions?

I built the stack as mstp on linux. I need to change the MAC address but I was not able to find the place to do it.

Hi All,
Trying to implement a small server example based on ti-rtos gcc (~256k SRAM), I thought I read somewhere this stack had a very small footprint (on the order of 40k but I can't find where I got this information). So far I have enabled only the "I am" service, "Read Property" Service enabled. I really only need Analog Input objects for my demo, but even without using those i am still 190k over the BSS size in my chip. Is this target just too small to handle this stack?

Best,

We has a project need the device use BACnet IP to provide data to controller, and the network number features might be required. Is the feature is worked in this stack library? We use the https://sourceforge.net/projects/bacnet/ before, but the feature does not seem to support.

Indent and style. It has been harder to find 'indent' on some platforms. I've been using clang-format for a lot of other projects, and it is easier to integrate into the continuous integration tools.
https://clang.llvm.org/docs/ClangFormat.html

Of course, finding a similar indent style to match the existing indent style in the BACnet Stack library using clang-format configurations has been challenging. But, clang-format does a much better job of preventing ugly code. Thus far I use the following - do you have any suggestions?

BasedOnStyle: google
AllowShortFunctionsOnASingleLine: None
AllowShortIfStatementsOnASingleLine: false
AllowShortLoopsOnASingleLine: false

Setup details:
BACnet server application running on Linux system (Ubuntu 18.04).
Yabe(Yet another BACnet explorer) on windows system to get the BACnet the server information.
Bacnet Stack from branch bacnet-stack-1.0

• To add multiple device object, we have modified Device_Count API so that we can have more than one device object. we can see multiple device objects in Yabe(yet another BACnet explorer) tool, but the fields(instance number, name) are same for all the device objects.

Checked multiple demos but not able to find the one with multiple device object. The gateway demo is adding multiple routing device but the demo is not getting compiled(instruction used: make -s -C apps/gateway). Inside CMakeLists.txt gateway related lines(527 and 528) are commented.

The objective of my project is to have multiple BACnet device object and each device object should have multiple analog/binary input/output objects.

While using the stack under Helgrind and DRD, I noticed some race conditions when the ring buffer was in use. Also I noticed that the dlmstp_master_fsm_task thread is never closed ever after dlmstp_cleanup() is called. I just thought I would suggest some fixes that are already present within our fork:
