Hello

i am cordova developer and i am trying to create cordova plugin for TC53e-RFID device using SDK 2.0.3.162 for our application
https://www.zebra.com/us/en/support-downloads/software/rfid-software/rfid-sdk-for-android.html?downloadId=37746677-7567-4b97-a54b-33dce8bdb7c2

Currently, the problem is that the in-build reader is not being found

using 

context = cordova.getActivity().getApplicationContext();
readers = new Readers(context, ENUM_TRANSPORT.RE_SERIAL);
availableRFIDReaderList = readers.GetAvailableRFIDReaderList();

got error when run "readers.GetAvailableRFIDReaderList()"

also i directly tried to get ReaderDevice using 
ReaderDevice readerDevice12 = new ReaderDevice("RE40", "COM_PORT", new RFIDReader("RFIDTC53E", 921600, "RE_SERIAL"));

but still got same error.

can please suggest any case that can be use in our plugin and read data from Tag.

I faced one issue regarding USB cable.
if in-build reader is connected in "123RFID Mobile" or "HH sample" application and i connect cable in mobile then reader is auto disconnect.

please provide developer document for find in-build reader and how to connect reader.

i also checked 123RFID Mobile application for test, it is working fine as expected and i need to get same result using cordova plugin.
