Pi & PN532 Board

by klomp on Mon Oct 21, 2013 12:13 am

I have followed all the instructions in setting up my Pi with this board. However, I keep getting the following error "Unexpected PN53x reply!". Any Ideas as to why?

I vaguely remember an inconsistency between the PN532 and libnfc-1.7, but don't know if that's still in effect. Let me pass this over to our NFC expert.
When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.

I fixed some of the wiring so that rx/tx on the ftdi are correct. Now I see more communications. However, when I use the pn532-diagnose I only get an error on the samconfiguration command. The inrelease reconfiguration and power down commands get a pn53x acked response.

The return data from the samconfiguration command is: 00 00 ff 02 fe d5 which the libnfc does not seem to understand. I wonder if the pn532 is returning some sort of error code.

Problem solved. Issue was that my raspdebian was version 6. Did the upgrade to weezy and things started working.
