tagtool.py stuck at touch a tag on raspberry pi

Asked by Toby Herbert

Hi there,

I am using a raspberry pi with a pn532 reader attached to it's GPIO.

Running tagtool.py finds the reader but doesn't see when you touch a tag on it. The same happens when running helloworld.py that sees the reader but not the tag.

Using libnfc's nfc-poll does see the tag so i am unsure why nfcpy doesn't.

Is it a supported device on the nfcpy library?

Kind Regards Toby.

UPDATE: It does work but it doesn't support Mifare Classic cards. Is there any way to use these?

Mifare Classic cards are not NFC Forum Tags and main goal for nfcpy is to implement NFC Forum specifications. It's simply a matter of priority and on my personal priority it's rather low. I'd happily accept merge requests if someone thinks it's necessary to support them. Technically nothing speaks against, although knowledge of read/write keys is required.
