PICO/iClass card not responding to CR95HF

I only need to get the UID of a iClass card. According to the IS15693 specification, it is MANDATORY for the card to respond to the INVENTORY command.

After the card is detected, I set the chip to this protocol format:

0x01 0x09

0x01 is ISO15693 protocol

0x09 is 26Kbps, Wait for SOF, 100% modulation, Single sub carrier, Append CRC.

Then I send the INVENTORY command:

0x26 0x01 0x00 // ISO15693 spec, table 1,5 and 9

0x26 is the flags:

Bit 1: Sub-carrier flag = 0

Bit 2: Data rate flag = 1

Bit 3: Inventory flag = 1

Bit 4: Protocol extension = 0

Bit 5:AFI flag = 0

Bit 6: Nb slots flag = 1

Bit 7: Options flag =0

Bit 8: 0

0x01 is the INVENTORY command

0x00 is the length of the mask, no mask used.

I have another ISO15693 card, and it responds in the correct manner to this request.

What needs to be different for the iClass card?

Please help.

What are the steps to read out the iclass card?

Hi,

I would suggest that you create a new post with a description of your issue rather than posting on an already answered post.
