I am using STM32. I can read the NDEF file from M24SR via I2c but I want to to delete it after reading so do I erase? I didn't found any example of erasing in app note.

    Hello,

    First of all, thanks for your interest in M24SR and STM32 products !

    Erasing an NDEF file is usually done by overwriting the NDEF file content.

    The simplest way to make the NDEF content "unvalid" is to put NDEF length to 0 ( offset address 0 of the NDEF file).

    I hope this answers your question,

    Best Regards
