1. Can you please give a note on steps how to run the Java client files on Mac.

Mac OS X 10.6.7 Java 1.6 

When I have tried to run or compile as class,
e.g 'javac IsmbNppConnection.java'
I have received error:
ava:68: cannot find symbol
symbol  : class IsmbNppException


2. Do we need to compile classes first, in a specific order, with a specific 
order?

regards,

Jim

I get:

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 

    at it.ismb.npp.PhoneToReceiver.main(PhoneToReceiver.java:38)

Can you please check? Maybe I'm doing something wrong but I'm doing it the same 
way as Reader2Phone and this works fine...

Thanks!

Jonas

Sorry to bug you with this cheap question but can you please assist in 
compiling this in eclipse?

Thanks!

Jonas

For ICS , the log is different for the data received from the phone. Does 
anyone know why?

Using a Nexus S with Ice Cream Sandwhich and try PhoneToReceiver, there is no 
data transfer.

I am using Ubuntu 10.04, the ACS ACR122U and the Nexus S.

It doesn't matter if I try PhoneToReader or ReaderToPhone I always get the 
error: "Device not supported, only ACS ACR122 is supported now", but on the 
pictures in the wiki it looks like you use the ACR122U too.

Hey,

I just managed to configure the NFC device properly and run the Java code 
example provided in NppFromReaderToPhone.zip. After running the code as an Java 
application I receive each time the same error on different platforms/operating 
systems. Furthermore the error code is not understandable for me, i.e., 0x63 
0x00 - Generic Error.

It seems the project works perfect and I really appreciate it 

but when I tried to send data larger than 41 bytes, 

the reader java source failed to receive the payload.

Does anyone know what's going on?

The situation is about sending data from phone to acr122 over npp.

I can send 41 bytes data. But never 42 bytes and what's larger.



* Below is the output when it fails to receive :

Hi,

does somebody know what is the precise description of those following bytes?

0xD4 0x8C 0x01 0x00 0x00 0x00 0x00 0x00 0x40 0x01 0xFE 0x0F 0xBB 0xBA 0xA6 0xC9 
0x89 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0xFF 0xFF 0x01 0xFE 0x0F 0xBB 0xBA 
0xA6 0xC9 0x89 0x00 0x00 0x06 0x46 0x66 0x6D 0x01 0x01 0x10 0x00 

I know that "0xD4 0x8C" is to configure as target and wait for initiators but 
what about the rest?

Thanks,
Mitch
