I see. I havent tested phone-to-phone communication yet, however, it sound to me like you are trying to write to the other phone's internal Smart Card. As far as I know there isn't any RFID tag...

Ok, I understand your your problem. For the "Writing an Image to an NDEF tag" example, you'll need a) a 6131 NFC phone and b) a rewriteable RFID tag. I simply tested the demo with the included Nokia...

Hello,
When you say "NDEF tag", I presume you mean the NFC tag (the internal RFID tag). NDEF is a standarized framework for writing & reading from a NFC tag. I am not sure what you mean, so I'll...

Hi,

Are you trying to read the tag using the phone or a midlet?

Try writing something to the tag first using the writing functionality of the phone.

I tried the solution on the link above. It didnt work on my Nokia 6131. It displays the message "Nothing to display". It could be interesting to see if this works on other phones.

Hello!

After hours and hours of searching, I have finally found the error.

The error is thrown because I initialized the PIMList several times, without closing and cleaning the resources...

Hello

I have followed numerous examples of the PIM API for adding and removing events. However, while I can add new events without any problems, I cannot remove the added events.

The error...

How big are the images?

Look at this page: http://www.rfid.co.uk/hf_transponders.htm. There is a couple of tags with 2Kb memory.

How about compressing the images using Huffman or similar...

Hello,

Well, have you checked out the PIM API provided by Nokia? PIM is the Personal Information Manager interface that gives you access to device specific data. Ie. calendar event and contact...

Thanks, that was usefull for me to know too.

I have read through the MAD documentation. It seems to me that the MAD area actually has to be created/exist before it can be used. Writing NDEF data...

Looks great!

Hi

My own experiences is that, NDEF formatted data is written to sector 2 (counting from 1), data block 4 (counting from 0). Sector 1 has two data blocks, 1 sector trailer and 1 manufacturer...

I have no experience with the OmniKey reader, but maybe you should try to compile one the examples from Nokia and try to see if it will read. Look at post number 6, I posted a link to one of the...

Alright, thank you very much.

I have a few more questions I hope you can help me with:

Can I use the standard key for all write operations?

If I have a byte array that is longer than 16...

Then, why doesnt this line working:

std_conn.write(autKey, dataBytes, 4);

thanks...

This reply is for "super_beda":

First of all, make sure that the phone is a NFC version of the Nokia 6131. From what I read, I understand that it is..

The tag that is provided in the sample...

I am testing on both. The output from the phone is the same as the emulation.

The wired thing is that, even writing 16 bytes to other than offset 0 gives a "MFStandardException". For instance...

I have tried to write a 16 bytes length byte array (as each data block is 16 bytes) as Ricardo proposed. Using the code below, returns no error at all, however when I read from the tag again there no...

Yes, the phone has a RFID reader and writer integrated. There is also standard software on the phone that lets you write and read from tags. However, the Nokia software on the phone, only lets you...

Hi

I bought a "Trikker Sample Kit" from TopTunniste, including a Nokia 6131 NFC phone. The Nokia 6131 NFC is compatible with all NXP Mifare 1K/4K/Ultralight/DESFire tags. The sample kit includes...

Dear valuable members of the Nokia NFC Forum:

I have a midlet that is able to both read and write NDEF formatted data to a Mifare 1K tag. I am also able to read data dircetly from the tags memory...
