Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

How does bR301 use API to appoint the specific protocol(T0 or T1) to connect the card

Post by Tarantino » Fri Oct 23, 2015 1:53 am

I'm using bR301 smart card reader to do the test. But now i have a question.
How does bR301 use API to appoint the specific protocol(T0 or T1) to connect the card ?
I mean i want to use bR301 to connect the card with specific protocol.
I have also checked the document but found nothing.
The Card.PowerOn() function doesn't have the parameter to do this. Any help?

Hi

We provide source code for customer. the source code made based on WINSCARD API(Linux and Mac os x call PC/SC API).
https://github.com/FeitianSmartcardRead ... ple%20Code

When you want to do communication with card, there have a API called SCardConnect, check below:
https://msdn.microsoft.com/en-us/librar ... 73(v=vs.85).aspx
http://pcsclite.alioth.debian.org/api/g ... 0696a8d6a5



LONG SCardConnect ( SCARDCONTEXT hContext,
LPCSTR szReader,
DWORD dwShareMode,
DWORD dwPreferredProtocols,
LPSCARDHANDLE phCard,
LPDWORD pdwActiveProtocol
)
Establishes a connection to the reader specified in * szReader.

Parameters
[in] hContext Connection context to the PC/SC Resource Manager.
[in] szReader Reader name to connect to.
[in] dwShareMode Mode of connection type: exclusive or shared.
SCARD_SHARE_SHARED - This application will allow others to share the reader.
SCARD_SHARE_EXCLUSIVE - This application will NOT allow others to share the reader.
SCARD_SHARE_DIRECT - Direct control of the reader, even without a card. SCARD_SHARE_DIRECT can be used before using SCardControl() to send control commands to the reader even if a card is not present in the reader. Contrary to Windows winscard behavior, the reader is accessed in shared mode and not exclusive mode.
[in] dwPreferredProtocols Desired protocol use.
0 - valid only if dwShareMode is SCARD_SHARE_DIRECT
SCARD_PROTOCOL_T0 - Use the T=0 protocol.
SCARD_PROTOCOL_T1 - Use the T=1 protocol.
SCARD_PROTOCOL_RAW - Use with memory type cards. dwPreferredProtocols is a bit mask of acceptable protocols for the connection. You can use (SCARD_PROTOCOL_T0 | SCARD_PROTOCOL_T1) if you do not have a preferred protocol.
[out] phCard Handle to this connection.
[out] pdwActiveProtocol Established protocol to this connection.
Returns
Error code.
Return values
SCARD_S_SUCCESS Successful (SCARD_S_SUCCESS)
SCARD_E_INVALID_HANDLE Invalid hContext handle (SCARD_E_INVALID_HANDLE)
SCARD_E_INVALID_PARAMETER phCard or pdwActiveProtocol is NULL (SCARD_E_INVALID_PARAMETER)
SCARD_E_INVALID_VALUE Invalid sharing mode, requested protocol, or reader name (SCARD_E_INVALID_VALUE)
SCARD_E_NO_SERVICE The server is not running (SCARD_E_NO_SERVICE)
SCARD_E_NO_SMARTCARD No smart card present (SCARD_E_NO_SMARTCARD)
SCARD_E_NOT_READY Could not allocate the desired port (SCARD_E_NOT_READY)
SCARD_E_PROTO_MISMATCH Requested protocol is unknown (SCARD_E_PROTO_MISMATCH)
SCARD_E_READER_UNAVAILABLE Could not power up the reader or card (SCARD_E_READER_UNAVAILABLE)
SCARD_E_SHARING_VIOLATION Someone else has exclusive rights (SCARD_E_SHARING_VIOLATION)
SCARD_E_UNKNOWN_READER szReader is NULL (SCARD_E_UNKNOWN_READER)
SCARD_E_UNSUPPORTED_FEATURE Protocol not supported (SCARD_E_UNSUPPORTED_FEATURE)
SCARD_F_COMM_ERROR An internal communications error has been detected (SCARD_F_COMM_ERROR)
SCARD_F_INTERNAL_ERROR An internal consistency check failed (SCARD_F_INTERNAL_ERROR)
SCARD_W_UNPOWERED_CARD Card is not powered (SCARD_W_UNPOWERED_CARD)
SCARD_W_UNRESPONSIVE_CARD Card is mute (SCARD_W_UNRESPONSIVE_CARD)
1 SCARDCONTEXT hContext;
2 SCARDHANDLE hCard;
3 DWORD dwActiveProtocol;
4 LONG rv;
5 ...
6 rv = SCardEstablishContext(SCARD_SCOPE_SYSTEM, NULL, NULL, &hContext);
7 rv = SCardConnect(hContext, "Reader X", SCARD_SHARE_SHARED,
8 SCARD_PROTOCOL_T0, &hCard, &dwActiveProtocol);
