How to run when NFC reader is connected to COM 5 on Windows?

Asked by Aiyee

I recently bought the itead NFC shield which uses PN532.

I used nfcpy-0.9.2 and not nfcpy-dev because I could not get nfcpy-dev working properly. My NFC shield is connected to a Windows laptop at Serial port COM 5.

Inside nfcpy-0.9.2, I ran the This is how I run it;

> python --device com:5:pn53x

The message I got was;

[nfc.clf] searching for reader with path 'com:5:pn532'
[nfc.clf] no reader found at 'com:5:pn532'
[main] no contactless reader found

Did I use the command correctly? What should be the right way to talk to a NFC shield connected to COM 5?

Try 'com:4:pn532' and 'com:COM5:pn532', both should be equivalent.

Can you help with this problem?
