Reader SCARD_SHARE_DIRECT connection error

[Klemen1337]

Hi, I am trying to connect to the reader with direct mode to write on LCD. It works on Linux, but not on Windows. Are the drivers different?

var LCD_CONTRAST = new Buffer([0xFF, 0x00, 0x6C, 0x00, 0x00]);

clearScreen: function (reader) {
    reader.connect({ share_mode: reader_object.SCARD_SHARE_DIRECT }, function (err, protocol) {
        reader.transmit(LCD_CLEAR, 40, reader.SCARD_PROTOCOL_RAW, function (err, data) {
            if (err) {
                console.log('error clearing screen:', err);
            }
        });
    });
}

I get [Error: SCardConnect error: Smart card was removed <0x8010069>] while trying to connect.

Cheers, K

@Klemen1337 I really don't know. What reader are you using? Does it have proprietary drivers? Do they distribute sample code to write on the LCD?

[Klemen1337]

I am using ACR1222L reader with drivers from the official page. I can pickup state changes like the example code, but cant transmit direct commands. The same code works on Linux, but not Windows.

The Windows CCID driver is far from perfect. The GNU/Linux one is much better :-)

Try again with a card inserted in the reader.

@LudovicRousseau yea I figured that out :stuck_out_tongue_winking_eye: It works if state is SCARD_STATE_PRESENT, but It is not how I want it to work.

[LudovicRousseau]

@Klemen1337 maybe ACS has a better driver.

[Klemen1337]

@LudovicRousseau ACS drivers are the one I used...

@Klemen1337 aren't there code samples for the functionality you're testing in their drivers / documentation? If there are and they work maybe we can migrate it to use node-pcsclite.

[LudovicRousseau]

I do not use Windows so I am not sure of what I write. I would not be surprised if you can't connect to a reader with no card inserted, even with SCARD_SHARE_DIRECT. Your bug would then be a limitation PC/SC on Windows and not a bug in node-pcsclite.

I'm closing this. @Klemen1337 please reopen the issue if you think there's something actionable. Thanks
