Problem with NFC Shield at Arduino Uno - No connection

Products & Technology Shields
#1

Hi,

i have bought a NFC Shield an connected it to my Arduino Uno. After I had downloaded the libraries I have uploaded a example programm to my Uno. But sadly I only got this text at the serial-monitor: “Didn’t find PN53x board”

Also after I have activated the debugging-function (#define PN532DEBUG 1), I had the mistake:

I got:
Hello!

Sending: 0x0 0x0 0xFF 0x2 0xFE 0xD4 0x2 0x2A 0x0

Sending: 0x0 0x0 0xFF 0x2 0xFE 0xD4 0x2 0x2A 0x0
Didn’t find PN53x board

How can I fix that mistake?

Jonas,

I am having exact the same problem, and I’m still not able to solve it. So how did you solved the problem?
