[GoogleCodeExporter]

What steps will reproduce the problem?
1.when I connect acr122s , I use usb-to-serial drivers .It can connect success 
using acr122s' sdk.
2. But this project cant run,the console shows:
3. Get factory
   Get terminals
   There are not terminals.
   invalid card terminal
   Exception in thread "Timer-0" java.lang.NullPointerException
    at it.ismb.npp.SenderToPhone$ThreadSender.run(SenderToPhone.java:109)

    at java.util.TimerThread.mainLoop(Unknown Source)

Is acr122s belong to acr122 series?It's the problem of the reader version or 
the usb2serial driver?Since acr122 is hard to buy,how about acr122u ?Thanks!

I am using ACR122U and Nexus S and I can see the same issue sometimes. 
But if I use HTC or samsung GT-I9300, the ACR122 LED keeps blinking and throw 
exceptions at terminal.iscardpreset(). 
Seems that it can't work other Android phone with version 4.0.

I have the same issue using Acr122s. Is a problem only for this device? Is it 
my mistake? What models of devices work well? Thanks!

Google Nexus S Android 4.0.4 does not give ATR for every ATR request.
This is a major issue with many ICS4.0.4 phones.

Hey, I have ACR122U-A2, and am happy to confirm lovero...@gmail.com's symptoms 
with my reader. Pardon the pun, but I have spent the last [almost] 4 hours 
staring at the code and cant seem to be able to fix this.

Hi, for those of you that are getting the null pointer exception at just list() 
failed:
you need to install the device drivers, that bumps the problem a few lines and 
I get the terminal name printed out at least. In addition,  I get the following 
error if I dont put the android phone *on* the card reader:

Get factory
Get terminals
Terminal name: ACS ACR122 0
Device not supported, only ACS ACR122 is supported now
Exception in thread "Timer-0" java.lang.NullPointerException

    at java.util.TimerThread.mainLoop(Unknown Source)
    at java.util.TimerThread.run(Unknown Source)


however, if I execute the code after placing the phone on the reader I get: 

Get factory
Get terminals
Terminal name: ACS ACR122 0
Device not supported, only ACS ACR122 is supported now
Exception in thread "Timer-0" java.lang.NullPointerException

Will post any updates or solutions when and if I find any...

Hello everyone. Currently working with ICS 4.0.4 Galaxy S3 and ACS122U 
(firmware 207). In my case, I managed to communicate the Galaxy S3 and the 
reader. The problem of null pointer, is terminal.isCardPresent (), can be fixed 
by changing terminal.waitForCardPresent(0). The result:
Get factory
Get terminals
Terminal name: ACS ACR122 0
card: PC/SC card in ACS ACR122 0, protocol T=1, state OK
Protocol:T=1
Called Procedure to Send data .. INITIATOR MODE
...
[DEBUG] {receiving [8 bytes]} 0xD5 0x41 0x00 0x83 0x44 0x01 0x90 0x00 
Finished

My problem is that it does not always work, I have often errors:
Exception in thread "Timer-0" java.lang.IllegalStateException: Card has been 
removed
at sun.security.smartcardio.CardImpl.checkState (Unknown Source)
at sun.security.smartcardio.ChannelImpl.checkClosed (Unknown Source)

at it.ismb.snep.IsmbSnepConnection.transceive (IsmbSnepConnection.java: 140),
or
Exception in thread "Timer-0" java.lang.ArrayIndexOutOfBoundsException

at it.ismb.snep.IsmbSnepConnection.rightProcedureEnhanced 
(IsmbSnepConnection.java: 172)
When conditions are accurate to the case in which everything works. Someone 
would know how could fix it?

I have the same issue. After running the app, I tried change "isCardPresent()" 
for "waitForCardPresent(MILIS)". After using that, the ACR122 is waiting for 
the terminal to approach, and when I do it, it begins beeping and blinking and 
the console just show me the following:

Get factory
Get terminals
Terminal name: ACS ACR122 0

4.2). Anyone knows the solution??? Thanks a lot!
