    Hi

    In Peer-to-Peer mode, two NFC devices can exchange data. In reader/writer mode, the NFC device is capable of reading smart poster tags. The modes are not mutual exclusive if i understand your question.

    please check https://projects.developer.nokia.com/ for sample projects and especially nfcinteractor that demonstrates everything you need. Code sources are open and available on Nokia Projects

    Re: Read/write tags with P2P

    Hi Izinin,
    If i use my phone in p2p mode is it possible to exchange data from a reader (NFC Reader) which is also in p2p mode .I want to read some data from smart poster and store it in my phone
    When I tap the phone to a reader the reader should read it .

    In c7 I guess there is no secure element I did the same thing with 6131 but struggling with Nokia C7.

    I had seen the nfcinteractor .Wanted something similar to it in Java ME.The source code provide here is C++.

    I have seen NFC Creator as well My app would reads the complete contents of a Mifare tag to a log file (default: E:\nfc\). and the SCL010 Reader would read the contents from E:\nfc

    Is it anyway possible

    Thanks for your reply

    Regards

    Hi

    if nfcinteractor project feature set is suitable for your needs , perhaps we need that project be ported to java just to provide example for others. I can explore the project porting feasibility but not right now. I will put it to my queue. I see it would be nice to have that port with or without design restriction list. What do you think?

    Hi

    In Card Emulation mode NFC services based on the use of the phone SIM card (Universal Integrated Circuit Card - UICC) as the secure element (SE). So having secure element is the matter of NFC mode. It is impossible to flash data on an external storage in Card Emulation mode otherwise it would be easy to clone credit cards and steal personal sensitive data. Such security flaw is so obvious that it cannot exists in the technology.
    SIM card is operated by a SIM card toolbox -- a closed API available for device manufacturers.

    you need to sign your app to use secure element. Additional info is referenced by links below:
