looks a lot like LudovicRousseau/pyscard-contrib#2

trying any example with transmit (here http://pyscard.sourceforge.net/pyscard-framework.html#selecting-the-df-telecom-of-a-card), with any tag, i get:

insert a card (SIM card if possible) within 10s
connecting to ACS ACR122U PICC Interface 00 00

IndexError: list index out of range
disconnecting from ACS ACR122U PICC Interface 00 00

when i get down to it with pudb, response is just [] in there, so of course it's out of range. First tried with python-pysdcard from ubuntu repository, then i built/installed from source (this repository). I'm having a look into scard.i, and SCardTransmit, but i have no experience with swig, so i'm not positive i'll find the cause on my own, so any idea welcome :). If i start gscriptor and run a script like FFCA000000, i do get an answer, so i guess pcscd is working correctly.

What happens with gscriptor if you send the APDU "A0 A4 00 00 02 7F 10"?

Sending: A0 A4 00 00 02 7F 10 
Received: 
wrong SW size for: 

Script was executed without error...

not much apparently…

Thanks for fast answer :)

edit: this made me understand (quite new to rfid, sorry) that what i want mainly, getting tag ID was simpler than i though, i was sending SELECT + FFCA000000 for that, when i only needed the latter part, and in this case, answer is immediate, so for now i'm settled, but if think there is a real bug to solve in pyscard for the DF_TELECOM (if it should work with any tag/reader), i can help debugging this further, it might be useful in the future.

Can you generate pcscd logs as described in https://pcsclite.alioth.debian.org/ccid.html#support and send the problematic APDU A0 A4 00 00 02 7F 10 using gscriptor ?

I've read a bit more about DF_TELECOM, which i was only trying because it was the example, it seems only about SIM cards, maybe it's normal that i don't get an answer for it with my simple rfid/nfc tags?

Sorry, i though keeping only the communication part would be more useful

The reader firmware is bogus.
It returns 80 00 00 00 00 00 0F 00 FE 00
bStatus = 0x00 indicating No Error
bError = 0xFE indicating ICC_MUTE, CCID timed out while talking to the ICC

The reader should report an error in bStatus so that the driver knows something failed and returned an error so that the upper layers, in this case pyscard, do not try to parse the empty result.

Can you follow https://pcsclite.alioth.debian.org/ccid.html#CCID_compliant please?

Your reader is already in the "unsupported" list but I want to know what firmware version you are using

Sure, here it is, thanks for looking into it and explaining, i've been told this reader was quite common, so though it would have good support, but maybe it's limited by a bad firmware, support is good enough for what i want for now anyway :), i guess i should have started with the support list.

You are using a "recent" firmware bcdDevice: 2.14.
I added a note to https://pcsclite.alioth.debian.org/ccid/unsupported.html#0x072F0x2200
It is not a bug in pyscard.
Thanks for your help.
