pcsc_scan not finding reader

yannick-couzinie commented 1 year ago

I am pretty sure that this is less of a bug, and more of me just not understanding how to use this software. I am on arch linux, I self compiled the latest version from github and am using this release https://github.com/frankmorgner/vsmartcard/releases/download/remote-reader-2.3/remote-reader-debug-2.3.apk from the app, as with the f-droid version I was getting the cold reset problem described here https://github.com/frankmorgner/vsmartcard/issues/201.

Expected behaviour

pcsc_scan should find a reader, after connecting the computer (vicc -vvvv --reversed) to the android phone (smart card reader/vpcd) as per bottom part of website that says that these programs should give some output.

Actual behaviour

pcsc_scan and opensc-explorer do not show any connected readers.

Steps to reproduce

On computer use vicc -vvvv -reversed
On phone tap the yellow button
Connection is shown as successfull but pcsc_scan does not show anything.

Logs

vicc -vvvv --reversed

The ports between vicc and remote-reader are correctly connected. However, they both try to speak the same protocol and don't understand each other. vicc waits for commands and calculates responses based on the python implementation of, e.g. an MRTD. remote-reader waits for commands and sends them to the phone's NFC hardware and receives the responses from the nearby contactless smartcard. (It's also possible to operate remote-reader as relay to vicc, but since it's not the default setup, I don't think you have it running this way.)

So first, please clearify how you want to roll... What do you want to access through which interface? If you want to access vicc through PC/SC (e.g. via pcsc_scan), you only need to install virtualsmartcard and restart pcscd, that's it.
