Communication problems from ACR122U to Phone about ismb-snep-java HOT 6 OPEN

Hi rpoor,

i had also the same problem. Now I have a temporary solution to the problem.
The only thing I did was just reboot my Android phone. Then it works only once. 
The problem is not yet solved. Anf if you touch the screen to beam, the screen 
fades up slowly, while the problem remains.
At some point the LLCP Link is deactivated. See below.
Is there any way to activate the LLCP Link using some commands?


My LogCat looks like :

That's right Sammy! My LogCat shows the same output. I have seen that if I turn 
off and turn on he NFC connectivity it works once till I repeat the process.

Any issue? Could someone help us? I think that it is an importan issue.

Thanks in advance.

Anyway, I think that the problem isn't due to the deactivation of the LLCP link 
because when the data is successfully sent the LLCP link is also deactivated.

I have seen that when the communication is correct:

D/NFCJNI(487): Failed to accept incoming socket  0x0096[NFCSTATUS_ABORTED]

Could that help us?

I can also see this message:

E/NFCJNI(487): phLibNfc_Llcp_Send() returned 0x006f[NFCSTATUS_BUSY]

I have searched for NFCSTATUS_BUSY in Google and I have found this:

Has this issue been solved? I'm getting the same error, and the only workaround 
that I know is to reboot the phone or reset the NFC.
