Re: [Open-NFC] Using an android Phone to talk to an reader (card Emulation)

[Tunc I. <tun...@gm...>]

Hi Julian,

I am also interested for the card emulation in the Android especially the
Mifare Classic cards. I know that using CyanogenMod on some specific set of
mobiles, you can emulate Desfire cards but any card using anything other
lower than 14443-4 (APDU) communication including Mifare Classic and
Ultralight cards. Using CyanogenMod means obviously rooting and flashing
your phone with Cyanogen custom ROM.

If I may ask, where did you get information that Mifare Classic cards can
be emulated using Android. Or if you managed your self, how?

Thanks in advance.

[Open-NFC] Using an android Phone to talk to an reader (card Emulation)

[Julian R. <Julian@Raufelder.com>]

Hey,

I am very surprised but eventually found a way to use the card emultion mode of Android phones with open nfc. I have researched a lot on the internet but nothing seemed to work.
Is it really possible with the Open NFC stack to emulate a Mifare Classic card? I can not believe :). Must the device be rooted or otherwise prepared? 

Please give me a short answer to my few questions. 

Thanks a lot!!!!

With best greetings,

[Open-NFC] NFC HTML for Tumblr

[Chris S. <cso...@gm...>]

Hi,

I am not a programmer or engineer, I only know the basics of programming. I
have looked through your site and elsewhere and can't find the answer to my
question.

Is it possible to write code to create an NFC integrated Virtual Card so
new laptops with NFC capabilities can download vcards via their mobiles in
close range to the laptop, from finding the information on a website (i.e.
my tumblr)?

If this is possible, does anyone have any NFC code for a virtual card that
I can paste into my Tumblr? I'm guessing it is more complex than just some
code, so does anyone know how I would set this up properly on my Tumblr?

Thanks very much for your help!

Hello,

 

It is indeed possible to use Card Emulation with Open-NFC compatible phones, however this feature is reserved for the phone manufacturer (restricted by Android system itself and the Google license).

Re: [Open-NFC] NFC emulator setting issue

[Sebastien D. <sde...@in...>]

The file is included in the archive you downloaded : MAN_NFC_1205-326 Open NFC - Android ICS 4.0.4 - Porting Guide v0.4.pdf

 

However please note that the last AVD we released has a bug, as described here:

http://sourceforge.net/mailarchive/message.php?msg_id=30159955

 

We will release a new AVD fixing this problem ASAP.

Re: [Open-NFC] nfc_hal_simulator.so library not found in Android emulator...

Well, as soon as the correct AVD file is online, you do not need to go through the compilation yourself. If you cannot wait for this image, then yes you can compile it yourself.

You can find the connection center tool in the SDK or Core editions of Open NFC. IT is an application running on Windows OS and “connecting” your Android emulator to the NFC simulator, also included in these archives.

Re: [Open-NFC] Porting open-NFC to a specific android target

You need not only a dedicated kernel driver, but also a dedicated HAL module in Open NFC (replace the nfc_hal_microread with a dedicated nfc_hal_***). This is documented here:

I write another mail in the hope to receive the necessary support to start my project.
As described in my previous mail , my target is to port open nfc library to an android platform (Sony XPERIA S ) which embeds a pn544 chip.
I downloaded the source code of the jellybean firmware for my phone and the 4.5.0. release of the open nfc libraries but i've soon realized that it would have taken more work to port them to a different hardware than microread module or securead. I ve tried to read the guides included in the core release but i still don't know exactly how to operate.

So my question is, starting from the files included into the android 4.5.0 release, what of them require a modification?? The kernel related driver i suppose , but how ?? i can't find any documentation covering this part of the porting.
I obviously don't ask you to make the work for me, but i need some instructions to get on the right way to compile a working version of android for my device with open nfc embedded.

Also at present time as far as i know nobody has ever attempted to integrate these libraries in an android device, so this project could contribute to the diffusion of the libraries to the smartphone world.

I hope in your support.

Thanks

Subject: [Open-NFC] OpenNFC Android Presence detection

Hi,

I've found an interesting behavior of OpenNFC on Android, which I do not understand. Maybe someone on the list can enlighten me?
After a READER_TARGET_DISCOVERED event is sent, the stack periodically sends an I-Frame + 4 bytes payload + CRC to the card:
02 FF FF FF FF (+CRC)
The card always responds with 1 byte:
02 1C (+CRC)

I'm assuming this is some kind of presence detection but I do not understand how it works and what protocol it uses. According to ISO 7816-4 a class byte of 0xFF is invalid (but there is no notion how a card has to respond to an invalid class byte). Also a response of only 1 byte is not valid according to ISO 7816-4.
So I assume OpenNFC is using some other protocol (loophole?) to do presence detection. Is this correct? How?

[Open-NFC] PN533 porting support with Open-NFC

[Tianhao <tia...@gm...>]

Hello,

I have a simple question on PN533 support with Open-NFC stack.

I'm using a NXP PN533 NFC chipset for my application and planning on using
Open-NFC stack. Does Open-NFC support PN533 HAL porting(from NXP SDK)?
Also, when I check the Core Edition, it seems that the "connection center"
only supports NFC device with UART, SPI or I2C interface. But the NFC
device that I'm developing is using USB. How can I have Open-NFC work
directly with USB interfaced NFC device? BTW, I have my USB driver working.

Thanks a lot for any suggestion or help,

Subject: [Open-NFC] How to develop driver for custom NFC chip

 

Hi all,

I'm a student, learning OpenNFC. My goal is to run OpenNFC stack on Linux with TI WL8 NFC chip. The chip supports NCI commands. I'm going to develop HAL-NCI driver. In general, I understand HAL API.

[SD] This is great project. Do you think you will be able to contribute the developed code back to the Open NFC project?

My questions are:

1)      Is HAL driver kernel or user space?

[SD] In general on Linux we prefer to run the stack on user mode. If you take the example of the nfc_hal_microread code, there is a very small part in kernel space to drive the hardware (I2C, GPIO) and the remaining is in user space.

2)      How to embed driver into stack?

[SD] That’s up to you to define this; in our existing porting we use a file interface (open, read, write, …)

3)      Is there open-source example for HAL driver?

[SD] Yes, the NFC HAL for MicroRead module is freely available.

 

Best regards,

Sebastien.
