CR95HF responding with 0x8300

Hi,

We are working with the CR95HF chip using SPI protocol.

We get the correct response for echo, protocol set (1443-A) and IDn.

However for a continuous SendAndRecv command with the value 0x04022607 we get the response 0x8300 which is unknown instead of 0x8700 since there is no tag in the field.

Any recommendations with this issue ?

Regards,

Sid

Hello Siddhesh,

The error code 0x8300 provided by the CR95HF is relative to a bad protocol select command. You might check with a tag ISO 14443 A in front of the reader that you can access it with the send/receive command. I believe that their is a mismatch in your protocol select command and so you got the error code associated to this bad command setting.

Best regards

PB
