JavaCard OS

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:

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.
