Is there any sample Apps read /write memory beyond NDEF file? I want to lock the NDEF file and then use memory beyond for proprietary usage. Thanks for kindly help.

    Hello,

    Reading beyond the NDEF file length can be done with the ExtendedReadBinary command.

    Please refer to the section

    ExtendedReadBinary command of the M24SR datasheet.

    You might also find useful the application note AN4433

    http://www.st.com/web/en/resource/technical/document/application_note/DM00105043.pdf

    , section 2.2 for more explanation on the command.

    Hoping this will help you.

    Best Regards,
