Communication problems from ACR122U to Phone #4

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Run the ReaderToPhone Code.
2. Place the phone up against the reader when ready.
3. The message is not sent.

What is the expected output? What do you see instead?
Instead of send the message, I see that output:
IN JUMP FOR DEP done..
[DEBUG] {sending   [10 bytes]} 0xFF 0x00 0x00 0x00 0x05 0xD4 0x40 0x01 0x11

What version of the product are you using? On what operating system?
Last version, Windows 7 and Nexus S with Android 4.1.2.

Please provide any additional information below.
I have a lot of questions about the code. I suppose that after "IN JUMP FOR 
DEP" we wait till the length of the reply is 7, what means that the phone is 
waiting the data. However, I receive the repplies you can see above.

Could you help me? Could it be because the phone sends that message while the 
thread is sleeping?

I have done the tests with Android Beam enabled and disabled with no 
differences.

I would be grateful if you could help me.

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.
