ISO15693 Error - MAM2

[enoe]

Hi all,

I'm working on MAM2 and I'm having a recurring error.

I have a succesful answer to MAM1 message and then I send:

80 00 00 11 90 2f aa fa a6 3f 71 31 12 00 c8 39 fc b9 32 e5 87

Where:
80 authmode by host
00 crypto suite AES 128
00 11 numbero of byte of MAM2 message (next 17 bytes)
90 is the step MAM2
2f aa fa a6 3f 71 31 12 00 c8 39 fc b9 32 e5 87 is the message.

I keep having this anser:

95 0f  (ISO15693 error).

Can someone help me?

Thanks

Hello @enoe 

Are you using the RFID Discover tool which is from NXP or an application that you wrote yourself?

In addition, before authentication please make sure if your key is active, that is to say, check if the key header is 0xE7.
