How to Control LED on ACR122 using smartcardio and Java?

How do I open nfctools library in NetBeans?

QUESTION

How to Control LED on ACR122 using smartcardio and Java?

Asked 2020-Apr-23 at 21:38

I am trying to use the smartcardio library in Java (JDK 8, NetBeans 7.4, Windows 10). I have tried many other libraries with no success.

The card reader (ACS ACR122U) came with an SDK CDROM but the necessary .DLL is not on the CD so I cannot use the ACS library.

Since my NFC device uses an EEPROM that is not supported by the nfctools library I cannot use nfctools.

My code is as follows:

As in the comments 0xff class of APDU command is not valid for cards, this is used to get the reader to interpret the APDU instead of send it to the card.

Not the same reader but this diagram make it clear

So don't try and wrap an APDU inside another APDU by duplicating the INS, P1, P2 and Lc fields

QUESTION

How do I open nfctools library in NetBeans?

Asked 2020-Apr-21 at 12:26

Background: I am trying to write a simple application in Java (to run on a Win10 laptop) to read the first 256 bytes of a NFC EEPROM (ST M24SR64-Y). The NFC EEPROM is in a hardware device my company makes.

That project is not going so well (I will probably be posting about that issue soon) but I am trying to figure out what I'm doing wrong in this simple application.

The Problem: I cannot load the nfctools library source code in NetBeans 7.4. The project name has a [unloadable] tag next to the project name in the Projects window. Right-clicking the project and selecting "Resolve Project Problems" provides the following Description:

Quick Fix

The project will indeed say "unloadable" when you first open the project, because you have not yet downloaded the Maven dependencies for the project.

Just press F11 in NetBeans to build the project (or click on the hammer icon).

This will automatically download all missing dependencies, as defined in the project's POM.

Detailed Steps

In case the above quick fix did not work - here are the steps from the start:

I assume you are referring to the NFC Tools here: https://github.com/grundid/nfctools

Go to the web page and click on the green "clone or download" button.

I chose "download zip" just because I did not want to clone.

I am using Windows 10.

(I am using Java 11 - but I assume that is less critical.)

Unzip the zip file "nfctools-master.zip" (I recommend using the free 7-Zip tool to do this).

I am using Apache NetBeans 11.1:

In NetBeans, go to File > New project > choose Category: Java with Maven, and also Project: Project with Existing POM.

Click on Finish.

Using the "Open Project" dialog in NetBeans, navigate to the unzipped folder "nfctools-master". The entry should have the Maven "Ma" icon, instead of the plain folder icon.

Click on Open project.

It will say "unloadable" at this point.

Hit F11 to build the project.

When I do this, the build ends with the following output in the NetBeans console:
