ST25 SDK fatal error on Mac OS X
Hi,
As though there are libraries available for Mac OS X, my simple application randomly (almost always) crashes, and it has something to do with the dynamic libraries provided, specifically streader.dylib.
Any thoughts would be appreciated.
I'm running a MacBook Pro with macOS High Sierra version 10.13.4.
My code:
public
static
void
main(String[]args
)throws
STException {
stReader
=new
STReader();
boolean
connected
=stReader
.connect();
connected
=stReader
.connect();RFGenericReader
mActiveRFReader
=stReader
;
if
(connected
) {System.
out
.println('Connected!'
);
String
name
=mActiveRFReader
.getName();System.
out
.println(name
+' is connected'
);
stReader
.initialize();List<
byte
[]>uidList
=new
ArrayList<>();
try
{
uidList
=mActiveRFReader
.getTransceiveInterface().inventory(RFReaderInterface.InventoryMode.NFC_TYPE_5
);
if
(!uidList
.isEmpty()) {Iso15693Command
cmd
=new
Iso15693Command(mActiveRFReader
.getTransceiveInterface(),null
);
cmd
.setFlag(Iso15693Protocol.HIGH_DATA_RATE_MODE
);
cmd
.resetToReady();
System.
out
.println(Helper.convertByteArrayToHexString(Helper.reverseByteArray(uidList
.get(0))));}
}
catch
(STExceptione
) {
e
.printStackTrace();}
}
}
Sometimes it crashes at mActiveRFReader
.getName()
[Console output]:
