Re: [accada-reader-user] killing and writing to a tag

[Matthias L. <la...@in...>]

Dear Sana
 
thank you for interest in Accada!
 
Unfortunately, in the current implementation of the reader-hal simulator
framework we don't support tag memory, kill and programID. That's why you
received the errors (which should actually be a different error message as
you state).
 
We would highly appreciate if you are willing to add these features to the
simulator framework. You would have to add tag memory to the simulator model
and implement read/write in the simulator controller. In addition, if you
would like to use the graphical simulator you would have to add methods/GUI
elements to write/display tag memory. Kill and programID should also be
straightforward to do.
 
You can take a look at the source code in the package
org.accada.reader.hal.impl.sim to get an idea of the simulator framework.
Actually, some of the tag memory stuff is already provided but not enabled
in all simulators. 
 
Let me know if you would like to go ahead. I can then give you more detailed
information about the simulator framework.
 
Best
Matthias

Subject: [accada-reader-user] killing and writing to a tag


Hello Everyone,
I have been experimenting with Reader Simulator and Test Client and have run
into a bit of problem with:
 
1. To kill a tag, I sent the following command:
<targetName>Shelf4</targetName>
<source>
<kill/>
</source>
 
I get the following response message:
<resultCode>23</resultCode>
<error>
<name>ERROR_MULTIPLE_TAGS</name>
</error>
 
This message does not seem to make sense as the read report produced in
response to the following request clearly shows that there is only one tag
with range of Shelf4:
<targetName>Shelf4</targetName>
<source>
<rawReadIDs/>
</source>
 
<resultCode>0</resultCode>
<source>
<rawReadIDs>
<returnValue>
<sourceReport>
<sourceInfo>
<sourceFrequency>0</sourceFrequency>
<sourceProtocol>not supported</sourceProtocol>
</sourceInfo>
<tag>
<tagID>009204F0004B00000ABC</tagID>
<tagIDAsPureURI>100100100000010011110000000000000100101100000000000000000000
101010111100</tagIDAsPureURI>
<tagIDAsTagURI>1001001000000100111100000000000001001011000000000000000000001
01010111100</tagIDAsTagURI>
<tagType>not supported</tagType>
</tag>
</sourceReport>
</returnValue>
</rawReadIDs>
</source>
 
Am I missing something here? Any help would be appreciated.
 
 

2.	Writing a given ID to a tag using the Source.writeID() command:

<targetName>Shelf4</targetName>
<source>
<writeID>
<id>100100100000010011110000000000000100101100000000000000000110101010111000
</id>
</writeID>
</source>
 
The response is:
<resultCode>0</resultCode>
<source>
<writeID/>
</source>
 
But when I try to generate the read report to check that the ID of the tag
has indeed been changed, I find that it has not changed. A closer look at
the messages generated by the Reader Simulator, I find the following:
.
23074500 [Thread-16] DEBUG org.accada.reader.rprm.core.msg.CommandDispatcher
-Calling Source.writeID()
23074500 [Thread-16] ERROR org.accada.reader.rprm.core.Source  - Reader
"SimulatorController" does not support programID operations
23074500 [Thread-16] DEBUG org.accada.reader.rprm.core.msg.MessageDispatcher
-Response message: <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
.
Is it true that writeID() command is not supported? What about the write()
command?. How hard would it be to get these commands working? I need to be
able to simulate a scenario where a tag's fields can be modified.
 
Thanks in advance... 
Sana
