  1. Re: Inserting a unique download identifier in a sisx file

    Ok, thanks for the fast reply.
    I think I'll try to use the OMA Download mechanism.
  2. Inserting a unique download identifier in a sisx file

    I have a Symbian application that'll be signed by a third party.
    A SMS is sent to the user with a link to download the application.

    What I'd like to do is to be able to identify the user who...

    Re: DataAdress for EGray2 Bitmap?

    It may look like it, but when displayed on screen, it displays a vertical line, and it looks like the whole image only takes about 1/8th of the data a EGray256 image would (as expected from a 1bpp...

    DataAdress for EGray2 Bitmap?

    I'm trying to get the raw data of a EGray2 Bitmap. I've tried using:


    TUint8* imageData = (TUint8*) iBitmap->DataAddress();

    I was expecting to get bytes containing data for 8 pixels, but all...

  6. Re: 6212 - how to store data from midlet into internal mifare

    I see two possible ways to solve this problem:

    1. Activate the card on the phone: in the main menu, go to NFC>NFC Settings and check that NFC is on and cards are always avilable.

    2. Change the...

    Re: PushRegistry problem

    In the MIDP tab of the emulator's preferences, you have to uncheck "Override default handset behavior" or select "OTA Provisioning".
    This way, the application will stay installed even after you...

    Re: Emulate a Tag

    Are you talking about emulating a tag in the emulator or having the phone behave as if it was a tag?

    The first one is handled by the NFC Manager of the SDK. You can't control this in your J2ME...
  9. Re: Nokia 6131 NFC and Secure Element of a MiFare SmartCard

    You don't need the internal Secure Element to use secure Mifare tags. You just need to use Nokia's extensions to JSR-257 for accessing the security part of the tag.
    The SDK documentation should...

    Re: [moved] RFID Reader Reach?

    The range is very limited. Something like 1cm for the 6131 and even less for the 6212 (it's easier to just touch the tag).

    Re: Everybody, Mifare 1k please help me!!!!!!!

    No, I use the Nokia 6212 Classic, so I don't know exactly how the ACR122U writes NDEF data on a Mifare tag. So I can't really help you with that.

    Re: Everybody, Mifare 1k please help me!!!!!!!

    The CRC should be explained in the pdf I've linked to in my last post.
    Yes, the NDEF Message should be written from block 1 of sector 1, though there might be some Mifare specific header there too....

    Re: Everybody, Mifare 1k please help me!!!!!!!

    03 E1 is the Application ID for NDEF Content.
    The C0 01 bytes are the MAD header. The first byte is a CRC and the second byte is an "info" byte. More details here.

    Re: Everybody, Mifare 1k please help me!!!!!!!

    I invite you to read Mifare 1K/4K specifications in order to get a better idea of how data is written on a Mifare tag.
    You can also experiment writing NFC data in the NFC Manager (with the checkbox...

    Re: ISO14443-4 Emulation and Secure Element

    You don't put MIDlet in the SE but cardlets (Java Card applications). The SE is a storage area where data is stored and accessed through Java Card applications. You can then access the data with a...

    It looks like you're trying to write in sector 14 with the default key. If it works on 2 phones but not on a third, this probably means that the sector 14 is locked on the 3rd phone (According to the...
