Ubuntu 10.10 + RFIDIOt + ACR122

[proempiet]

I am trying to got RIFIOt running with an ACR122 I get to the last point in reading the tags then I get the message below.

>>>

Does anybody know what is wrong?

You're further than me, I think... But, same reader, similar problem.

The svn copy of pyscard fixes the undefined symbol in the beginning.

svn co https://pyscard.svn.sourceforge.net/svnroot/pyscard pyscard

if not T1 then T0 protocol
I'm new to Python, not sure if user can choose protocol...
if T0 then response is 61xx where xx is length of data
get data with a subsequent 'get data' command
- this is GOOD if you are attempting 'wrapped; FF mode
- I havnt got there yet

still stuck on Python weidness...
if you dont set
hcard = None
then Python crashes if you test hcard
.... what is less than None??
.... what is hcard anyway???

I will attempt to set it to 'TOAST' if not None <<do NOT do this

hcard is card handle

File "/usr/local/lib/python2.7/dist-packages/smartcard/scard/scard.py", line 505, in SCardControl
return _scard.SCardControl(*args)

TypeError: Expected a python long as SCARDHANDLE.

ps: I was doing much better BEFORE i installed the Linux ACS driver - it seems that some default reader driver was better!!

RFIDIOt is stuffed full of low level reader-type flags and fields...
My Advice: Abandon automatic detection of readers.
First step: decide on your reader and dont go reading obscure EEPROM bytes, they may not be there...
