Hi all!
I have a react native app where I can print rfid tags. I found some example, and I can get a bluetooth connection to the printer and print the tags correctly.
But I need to get the tag id, too. I use zpl language in order to set how to print the tag, and I read about to use RI command to get RFID tag ID. But I can't understand how to get it.
This is the code I'm speaking about:
<code>
Connection printerConnection = null;
ZebraPrinter printer = null;

printerConnection = new BluetoothConnection(macAddress);

try {
printerConnection.open();

if (printerConnection.isConnected()) {
printer = ZebraPrinterFactory.getInstance(printerConnection);
PrinterLanguage printerLanguage = printer.getPrinterControlLanguage();
byte[] testLabel = getTestLabel(printerLanguage);
printerConnection.write(testLabel);
}
</code>
I expected <code> printerConnection.write(testLabel);</code> could return the tag id, but it seems return only void.
Do I have to listen some events in order to get that id?
How can I get it?
Thanks in advance :-)
