I am new on the forum.
I have some issues with LLCP understanding..

I already able communicate between 2 NFC devices. However, my code works only on one way.
I can push a message to the target but I can't succeed to receive one from target.

here my log file with big steps of LLCP

Send Symm
Initiator -> send Symm [9]: 74 06 0F 06 D4 06 00 00 00 
>>>| Symm, DSAP=0, SSAP=0
Received data which was send from the Target

<<<| Connect, DSAP=1, SSAP=33


Send a Connect to the Target
Initiator -> send Connect [26]: 74 17 0F 17 D4 06 01 05 21 06 0F 63 6F 6D 2E 61 6E 64 72 6F 69 64 2E 6E 70 70

how to get my data from target???
Send receiveReady  or I ???
Initiator -> send RR [10]: 74 07 0F 07 D4 06 03 43 61 01 
>>>| Rr, DSAP=16, SSAP=33



Send a Disconnect to the Target
Initiator -> send Disconnect [9]: 74 06 0F 06 D4 06 04 41 61 
>>>| Disc, DSAP=16, SSAP=33

Could you explain me the LLCP workflow? the NFC forum documentation is not clear enough for me.

How can I receive the data from my target?
Do I have to send an I PDU ? to inverse the DSAP and SSAP? Do I have to fill the information parameter if yes with what information?
I have done some tests without success

Many thanks,
jmc

1. Connect to LLCP socket with service name com.android.npp
2. Send the NPP Header following by NDEF Entries as defined in the Data Format section
3. Disconnect the LLCP socket

http://static.googleusercontent.com/ext … otocol.pdf


Looking at the log I found that Android sends the Connect LLCP using 0x06 0x0F as the first 2 bytes followed by the service name. So it is using PDU Type 1011 which according to NFC forum is Reserved. Also the service name is not according to the NFC forum LLCP service uri specification which should be something like urn:nfc:sn:<servicename>.

also while sending the NPP data it doesn't follow any of the LLCP forum specific messages. It just pushes NDEF messages with ist own NPP header without using any of the defined LLCP message exchange format.

So can anyone tell me how does the android NPP push protocol is implemented on top of LLCP?

I got some issue about LLCP connection with Google nexus s, my nfc board is NXP PN533. After got the LLCP information from Nexus S, our side just use InDataExchange response for "01  00  00", later it came with the 0x13 error code, i think maybe because "01 00 00" was not an avaiable PDU can be recognized by Nexus S LLCP, but i don't know which PDU format is correct in this situation, if anybody know some informations about this?

Please reference the following log:

first of all, thanks for libnfc and all the tools around it. Great work!!

I did some experiments with libnfc-llcp in order to get a basic understanding for
P2P transfers using LLCP. I tested with llcp-test-server and client and it caused
some kind of hang condition during tests and the inability to start the test code
again after killing the server and client codes. (btw: nfc-dep-target and inititator
examples from libnfc work fine)

Here my detailed problem description:
I am using two NFC readers (ARYGON, ADRB1US00) on one computer, the server code
was slightly modified in order  not to use the same reader as the client.

On the server side I started:
./llcp-test-server --mode=target

On the client side:
./llcp-test-client --mode=initiator --test 1

Both sides seem to transfer data as expected, but a some point the communication
stops. Especially the client seems to have finished communication, and hangs during
MAC Link deactivation.

The server and client program can't be killed by pressing Ctr+C, only the kill
command works. After killing client and server, a restart of the client oder server code does
no longer work (nfc-list still works). No output, it just hangs. Unplugging and plugging in the readers
does not change anything sad Resetting USB-Ports also does not work. I fact the
only thing that works for me is rebooting the machine.

I am using latest svn versions of libnfc and libnfc-llcp. I am testing on Ubuntu 11.10 x86_64.

Here are the outputs (Is there a possibility to submit the full as an attachment? The two logs
exceed the limits, so I can only post parts of it...)

The "-nxp" suffix suggests it's catering to NXP's PN544 found inside the Nexus S, currently the only NFC equipped Android device.

Now, the only NFC capability exposed in the Android Java API for now is simple tag reading -- now I am wondering whether P2P functionality would be accessible to apps via additional native and/or Java code, and whether that would require rooting the Nexus S or not. (The last commit says "disable NFC P2P functionality", uh oh seems like root will be required to undo that.)

The situation seems similar to Bluetooth where limited Bluetooth functionality is available in the official Java API but most of what the BlueZ stack offers can be accessed via additional Java code like Bluecove.

If anyone managed to get their mittens on a Nexus S and/or can judge this by looking at the code, your feedback appreciated. Access to NFC P2P functionality decides whether I will buy a Nexus S or not.

Any ideas why the standard command "jump for dep" doesn't recognize and activate the mobile phone?

I try to send data to a Nokia 6212 with PN533.
I send the letter several times.
But I get an error "0x13" in return (error format DATA).
Can someone tell me if I am on track to send DATA to GSM?

The NFCID3 GSM is 00 00 00 00 00 00 00 00 00 00.

Here is the script:

May be somebody know:

1) How autostart midlet on nokia to p2p  after touch mobile to ACR122 ? (i'am read all forum nokia - resultless)
2) How send NDEF tag (example mifare) from ACR122 ? (as workaround for start midlet after touch mobile)
May be send APDU byte array?

Thank you.
