Hello Daniel,

I'm the author of LTK-Perl and creator of the original llrp xml xsd
documents.

I created them when I worked for Impinj.

I am happy to help you getting any updates uploaded.

Hi There,

I have been tasked with updating the ltk toolkit with our latest changes.  I am still pretty new to the company and was hoping you could help me identify the contacts for making this happen.. I plan to speak with some folks here at Impinj to see if they know but that could take some time.. I thought I'd send an email to you in the hopes you may know faster.

Re: [ltk-d] LTKC on Windows?

[John R. H. <jh...@po...>]

Hello Jan --

Are you planning to run LTK-C on a microcontroller or on Windows? If you're
running on a micro, I'm not clear where Windows compatibility enters the
picture.

Anyway, C is portable so you should be able to get it running on Windows
platform or a micro. Most of the work of LTK-C is platform independent.

Also for experimentation, Perl is portable as well so that will run on any
platform.

The C++ and a C#.NET variants of LTK were specifically intended for Windows.

[ltk-d] LTKC on Windows?

[Jan-Philipp K. <jan...@on...>]

Hello,

i am developing the microcontroller of a RFID Reader which is not (yet)
LLRP compliant. So the aim is to make this one understand LLRP Messages.
For this aim i would like to use the LLRP Toolkit for C (LTKC). I
downloaded every package on the sourceforge page:

http://sourceforge.net/projects/llrp-toolkit/files/llrp-toolkit/ltkc/

but everythin seems to be for LINUX?! Is there a distribution of LTKC for
Windows? I've read in the INSTALL.TXT for LTKCPP (C++) that it can be used
with Visual Studio. But this seems not to be the same for the LTKC?!

Is there a way to use the Library for C on Windows? And is it possible to
use it for microcontroller programming IDEs like Keil uVision? ( I use this
one)

Thanks

Jan K.

[ltk-d] RFID multi-reader question

[Randy C. <ran...@sh...>]

I am currently developing a web service to listen for LLRP tag events from
multiple readers. There is a problem unless I am missing something simple.
In receiving the tag event I am not able to distinguish what reader the tag
event cam from. What am I missing? I have gone through the specs for LLRP
1.1 and from what I see the tag event does not include any information as
to the reader itself. I get the tag data and the antenna port but nothing
on the reader. I was surprised that reader information was not included in
the event. I hope that I am missing something stupid. Any help would be
greatly appreciated.....

Thanks

[ltk-d] .NET LLRP Toolkit Help

[Kristopher B. <kg...@gm...>]

Hi I am putting together an RFID application and I would like to use the
.NET version of the LLRP Toolkit. However, I am having a lot of trouble
getting the project to build.

 

I put the llrp-1x0-def.xml file in the LLRP directory.

 

I built a new CodeGenerator.dll and placed it inside the project.

 

I am getting an error the CodeGenerator.LLRPCodeGenerator can not be found.
I unloaded the project and checked the name and path. Everything looks
correct.

 

 

Have you ran this library on Visual Studio 2010 ? how about with .NET 4.0 ?

[ltk-d] LTKJava Release 1.0.0.7

[Christian F. <flo...@MI...>]

Hi everyone, 

I released a new version of the LLRP Toolkit for Java this weekend. The new release 1.0.0.7 comprises a number of minor bug fixes that were committed to the version control system a while ago, but had not been released.

For details, please see the changelog:

https://sourceforge.net/projects/llrp-toolkit/files/llrp-toolkit/ltkjava/1.0.0.7/

[ltk-d] Slow read rate on Impinj readers

[Benedikt O. <ost...@in...>]

Hi all,

I'm using LTK (ltkjava-1.0.0.6-with-dependencies.jar) to read and write 
the user area of EPC Gen2 tags. I am facing the problem that I achieve 
only very low tag read/write/access rates. I tested my code both with 
the Impinj Speedway and also with the Impinj xPortal reader and never 
achieved access rates above 1 second per tag. My code is based on 
http://learn.impinj.com/2010/09/reading-and-writing-user-memory-with.html. 
I tried several RoSpecs 
(http://sourceforge.net/mailarchive/forum.php?thread_name=A5D3A6D766212148A1995037718C729CF30C5ABF3C%40MBX7.EXCHPROD.USA.NET&forum_name=llrp-toolkit-devel) 
without effect. Note that the MultiReader software from Impinj features 
high access rates with both of these readers.

The LLRP specification did not help, either. Apparently, I am not the 
only one with this problem: 
http://fosstrak.wordpress.com/2009/12/15/maximum-reads-per-second/

Any help would be appreciated.

Cheers,

Benedikt

Re: [ltk-d] Handling Keepalives with LTK-Java

[Hugo H. C. P. <hug...@li...>]

Hi C.J.

Ensure you have next lines after connection:

        // KEEP_ALIVE messages are being forwarded to the LLRPEndpoint
        connection.getHandler().setKeepAliveForward(true);

Also, you must implement next lines in your messageReceived() method:

        if (llrpMessage instanceof KEEPALIVE) {
            log.debug("received keepalive message from the reader: " +
readerId);
            setAlive(true);
        }

Regards,

HHC

[ltk-d] First seen and last seen timestamp

[Roberto V. <rob...@gm...>]

Hi everyone,

this is my first message in LTK newsletter, despite I've been using java
LTK for a long time.
My question is mostly related to LLRP protocol rather than LTK itself.
Anyway, I hope you can answer my question.

On EPCglobal LLRP standard I read: "FirstSeenTimestamp: The Reader SHALL
set it to the time of the first observation amongst the tag reports that
get accumulated in the TagReportData", and similarly for the LastSeen.

But I'm not able to have different FirstSeen and LastSeenTimeStampUTC
values in my TagReportData Objects. They have always the same value. I
think I have some misconfiguration in my ROSpec, but I can't really
understand.

My goal is to know when a tag enters and leaves the antennas ranges,
knowing that the tag transit is quite fast (up to 3 seconds).

Can you help me in configuring my ROSpec? Which type of start/stop triggers
have I to use in both ROSpec and AISpec ?

Thank you,

Roberto

[ltk-d] LLRP Toolkit Question

[Manav D <cre...@gm...>]

Hello,

I am starting to develop an RFID solution for the company that I am working
on. I came across your great toolkit that can help me with this.

My question is, is there any C# support for it? Since I do not know java
that well, any help you provide me to get up to the speed on how could this
toolkit be used from within C#, it will be great.

I appreciate your time and effort for putting together this great toolkit.

[ltk-d] Handling Keepalives with LTK-Java

[C. J. <ud...@ya...>]

Hi everyone. 

I've developed a complex RFID middleware using the LTK-Java library but I still got an open (apparently dumb) point: I can't handle the keepalive messages from the reader.

The thing is, I can see in the Logger all that kal messages (as if I use some sniffer such as Wireshark), but ain't no notification received by the main interface, the method messageReceived() in the class implementing the LLRPEndpoint interface.

Obviously they are there, so I do really think that the LTK isn't forwarding the keepalives "all the way up" thus I can treat them as the rest of messages (READER_EVENT_NOTIFICATION, RO_ACCESS_REPORT, etc.).

Does anyone out there know how to set the LTK to kick out the keepalives through the messageReceived() function so I can handle the connection between the stations (the readers) and the module that will be interacting with my middleware? I'd need to show all the reader connection statuses.

Every try to shed some light will be very appreciated.


Kind regards.

Some information you might be aware of:
Using Impinj's Octane 4.8 with LTK-Java 10.14.0.240 with dependencies.
Working with Impinj's Speedway Revolution UHF Reader R-420.
Client initiated connection (reader awaits for connection).

Hello Dan,

I'm the main active moderator of the list at this point. Still available
for minor maintenance issues.

When I wrote LTK-Perl, I worked for Impinj. I'm an independent contractor
now. But I know C, C# and a lot about the LTK implementations. So I'm
available to provide support hours given business arrangements can be
worked out.

Others that want to help with maintenance are welcome as well, of course.

[ltk-d] .net maintenance?

[Kuester, D. G. <dan...@ni...>]

Hi,

I have a test app I wrote way back in June 2009 in MSVC# with .net.  I was hoping to update to maximize compatibility with newer readers and update to support LLRP 1.1. I'm looking through the LLRP.net cvs tree, and from the last commit it's looking likely that it is not maintained.

Is there anywhere else that these bindings are being maintained? Are there plans to pick up maintenance of this?

Thanks,

[ltk-d] frequency antenna

[<mic...@li...>]

 Hi, my name is Miky, we are using for our project, the reader Speedway  
Revolution R220 (IPJ-REV-R220-EU11M) and I wanted to ask you a question about 
its configuration. I wanted to know if it is possibile to configure So that the 
reader uses the antennas on separate channels for example:
Antenna 1 only works on a sub-band antenna 2 only on the other subband. 
example (antenna 1 in 865.6 -> 866.4) (Antenna 2 in 866.6 -> 867.4).
If you can not get what I wanted to ask you kindly how can I solve this 
problem is very urgent.

Waiting for your feedback, thank you and greet you in advance.

[ltk-d] Setting access password.

[Dan L. <Dan...@8r...>]

All I want to do is modify the c++ example code that reads tag ID's to set and lock the access password and then use that password for reading the tag ID.

I have attempted to read the forums and code documentation, but am not clear on the 'big picture' usage of the C++ API to accomplish this goal.

You can poke around the CVS tree interactively:

http://llrp-toolkit.cvs.sourceforge.net/viewvc/llrp-toolkit/LTK/LTKC/

There is a drop down that says "Sticky tag" which you can use to see the
tagged versions including ltkc_1_0_0_8 and ltkcpp_1_0_0_8

Probably some other header file was including these before and was masking
an implied dependency. Certainly it would be better to include them
directly.

Re: [ltk-d] Building ltkcpp 1.0.0.8 for linux, but where's the makefile

[Klaus H. J. <kh...@ly...>]

Hello Again!

I finally opened my eyes and saw that what I downloaded was the prebuilt stuff with header files. I do however still miss being able to download source files.
I did manage to checkout the latest source from cvs, but which tag should I use to get the latest official release?

I could furthermore not make the head revision compile without inserting #include <stdint.h> and #include <stdlib.h> here and there in the source files.
I'm compiling of a Fedora14 system with gcc 4.5.1.

Can anybody point me towards downloading source files for the 1.0.0.8 release?
Is there a good explanation why I cannot build the source as is?

Klaus Jacobsen

Subject: [ltk-d] Building ltkcpp 1.0.0.8 for linux, but where's the makefile

Hello
Downloaded ltkcpp from here: http://sourceforge.net/projects/llrp-toolkit/files/llrp-toolkit/ltkcpp/1.0.0.8/
Wanted to build .so file it according to instructions here: http://sourceforge.net/apps/mediawiki/llrp-toolkit/index.php?title=LTKCPP#INSTALLING_AND_BUILDING_THE_LLRP_Tool_Kit_for_C.2B.2B

But when unzipping the zip/tgz file I find no makefile only sourcefiles.

Can anybody point to instructions on how to build a .so file for linux?

Re: [ltk-d] LTK .NET MSG_RO_ACCESS_REPORT callback not invoked

[Jeffrey H. <je...@am...>]

I built from the 1.0.0.5 source bundle published on Sourceforge here:
http://sourceforge.net/projects/llrp-toolkit/files/llrp-toolkit/ltknet/1.0.0.5/ltknet_src_1_0_0_5.zip/download

The version I had trouble with is this:
http://sourceforge.net/projects/llrp-toolkit/files/llrp-toolkit/ltknet/1.0.0.8/LTKNet_x86-win32_1_0_0_8.zip/download

I don't know the details of CVS access, as I was just using the published bundles on SF, and 1.0.0.8 does not seem to have a source release there. I'd be happy to help troubleshoot, to the limit of my .net abilities (I'm really more of a Java guy, and just learning the platform to help out on other projects with our company).

Thanks for replying, and sorry for responding late. Last week, I was on site fixing an issue and distracted by the amount of work. I resolved the issue by reverting to LTK .NET 1.0.0.5 from 1.0.0.8, after a colleague suggested building the toolkit from source and stepping through it with a debugger. When I did that, my toy program (which I condensed down from my real problem) worked immediately, and the same applied to the service on the headless system I was fixing.



So you built from tip of cvs or you used an old release (1.0.0.5)?

Trying to figure out if you think there is a problem with the current cvs, 1.0.0.5 or 1.0.0.8.

Thanks,
