    The pass week I wrote all the AES keys and I switch the level to the level 3. I obteined a positive response. But today I use the TagInfo App for NXP and it says that my Mifare Plus EV1 is in level 0. Also when I tried to save all the keys and switch the level everytime it appears the response 0Bh, this says in the DataSheet: "The command was received while the PICC is not in the SL1MFPAuthenticatedISOL4 nor in SL1NotAuthenticatedISOL4 or the command was received while another command is ongoing."

    Do you know why appearse this message (0Bh)?

    Thank you very much.
