NDEF_TAG is detected but ISO14443_card is not detected

[jhansiprasad]

hi everybody

i am using Nokia_6131_NFC_SDK_1_1. i wrote the code for to detect uid of smartcard ,when i am using Target_type.NDEF_TAG its detecting and displaying the taguid and Url , but when i am using Target_type.ISO14443_CARD its not getting detected.Its doesnt display anything.

So wat would be the problem? Can anyone give the solution for this problem?
Pleasseeeeeeee...


Thanks in advance..

i think card is not a ISO14443 type card. which card you are using ?

i think card is not a ISO14443 type card. which card you are using ?

Thanks for the reply...........

I am using ISO14443CARD...

if the code is in a single class it is working but when divide into two classes its not working..........
like one is for midletclass and another is for tagdetectionclass

here i am calling detections method.......

see in the bellow code..........

package test;

import javax.microedition.contactless.DiscoveryManager;
import javax.microedition.contactless.TargetListener;
import javax.microedition.contactless.TargetProperties;

public class Detection implements TargetListener{
ISO14443Connection isoConnection ;
ShowISO14443Connection s;
Detection(){

}
public void detections(){
try
{
System.out.println("_________start__________");

DiscoveryManager.getInstance().addTargetListener(this,TargetType.ISO14443_CARD);
// s.Display();
}
catch (Exception ex)
{
s.Display();
}
}
public void targetDetected(TargetProperties[] targetProperties)
{
System.out.println("_________11111111111__________");
for (int i = 0; i < targetProperties.length; i++)
{
TargetProperties tp = targetProperties[i];
//form.append("uid before ISOConnection: " + tp.getUid() + "\n");
if (tp.hasTargetType(TargetType.ISO14443_CARD))
{

System.out.println("_________2222222222222__________");
//form.append("Target is ISO14443_CARD\n");
try
{
/*form.append("url: " + tp.getUrl(Class.forName(
"javax.microedition.contactless.sc.ISO14443Connection"))
+ "\n");*/
isoConnection = getISO14443Connection(targetProperties);
//String statusWord=doSelect(isoConnection,APDU_SELECT,"SELECT");
//form.append("uid: after ISO===============> " + tp.getUid() + "\n"+statusWord);
}
catch (Exception ex)
{
//form.append(ex.toString());
}
}
else
{
//form.append("Target is NOT ISO14443_CARD\n");
}
}
}
public static ISO14443Connection getISO14443Connection(TargetProperties[] tProp) {

for (int j = 0; j < tProp.length; j++) {

TargetProperties tp = tProp[j];
String tagID = tp.getUid();

/*for(int i=0; i<cardUids.length; i++) {

{

}
catch (Exception e)
{
e.printStackTrace();
}
}
}
}
}

return null;
}
public String doSelect(ISO14443Connection isoConnection,byte[] APDU,String APDUType)
{
byte[] resByteArr;
StringBuffer sb = new StringBuffer();
String SW1="";
//successFlag=false;
try
{
resByteArr = isoConnection.exchangeData(APDU);
for(int i=0 ;i < resByteArr.length;i++)
{
sb.append(resByteArr[i]+ " ");
}

}

}


please solve the problem................

[esunilkumare]

please use the CODE tags (also well intended) while posting codes so that it is readable.

in this case please post the output of the above code-listing while showing a ISO14443 card

package test;

import javax.microedition.contactless.DiscoveryManager;
import javax.microedition.contactless.TargetListener;
import javax.microedition.contactless.TargetProperties;
import javax.microedition.contactless.TargetType;
import javax.microedition.contactless.sc.ISO14443Connection;



public class Detection implements TargetListener{
ISO14443Connection isoConnection ;
ShowISO14443Connection s;
String Uid;


Detection(){
detections();
}




public void detections(){
try
{
//s.Display();
System.out.println("_________start__________");
DiscoveryManager.getInstance().addTargetListener(this,TargetType.ISO14443_CARD);
}
catch (Exception ex)
{
s.Display();
}
}



public void targetDetected(TargetProperties[] targetProperties)
{
System.out.println("_________11111111111__________");
for (int i = 0; i < targetProperties.length; i++)
{
TargetProperties tp = targetProperties[i];
Uid=tp.getUid();
s.display(Uid);//its the method in midlet class
}
}
}

output:

while showing the card its display nothing
