CaenUhfSample

Sample application for Caen UHF reader on C-One

Prerequisites

CpcSystemServices shall be installed on your device.

Please install the last version available on FDroid available on www.coppernic.fr/fdroid.apk

Set up

build.gradle

repositories {
    jcenter()
    maven { url 'https://artifactory.coppernic.fr/artifactory/libs-release' }
}


dependencies {
// [...]
     // Coppernic
    implementation('fr.coppernic.sdk.cpcutils:CpcUtilsLib:6.17.0')

}

Power management

• Implements power listener

  private final PowerListener powerListener = new PowerListener() {
        @Override
        public void onPowerUp(CpcResult.RESULT result, Peripheral peripheral) {
            if (result == CpcResult.RESULT.OK) {
                //Caen UHF reader is ON
            }
            else{
                //Error while powering Caen UHF
            }
        }

        @Override
        public void onPowerDown(CpcResult.RESULT result, Peripheral peripheral) {
           //Caen UHF reader power off
        }
    };

• Register the listener

@Override
    protected void onStart() {
// [...]
        PowerManager.get().registerListener(powerListener);
// [...]
    }

• Power reader on

// Powers on Fingerprint reader
ConePeripheral.RFID_CAEN_R1270C_GPIO.on(this);
// The listener will be called with the result

• Power off when you are done

// Powers off OCR reader
ConePeripheral.RFID_CAEN_R1270C_GPIO.off(this);
// The listener will be called with the result

• unregister listener resources

@Override
    protected void onStop() {
// [...]
        PowerManager.get().unregisterListener(powerListener);
// [...]
    }

Reader initialization

Create reader object

• Get reader instance

    private CAENRFIDReader reader;
    ...
    
    if (reader == null) {
            CAENRFIDReader.getInstance(context, new OnGetReaderInstanceListener() {
                @Override
                public void OnGetReaderInstance(CAENRFIDReader caenrfidReader) {
                    reader = caenrfidReader;
                }
            });
        }

• Connect to the reader

     try {
            reader.Connect(CAENRFIDPort.CAENRFID_RS232, CAEN_READER_PORT);
        } catch (CAENRFIDException e) {
            e.printStackTrace();
            return CpcResult.RESULT.CONNECTION_ERROR;
        }
    

• Create listener to get tag result

  private CAENRFIDEventListener caenrfidEventListener = new CAENRFIDEventListener() {
        @Override
        public void CAENRFIDTagNotify(CAENRFIDEvent caenrfidEvent) {
            Timber.d("Tag received!!");
            ArrayList<CAENRFIDNotify> tags = caenrfidEvent.getData();
        }
    };

Start inventory

• When your reader is initialized and connected. Start inventory

    Timber.d("Start inventory");
    CAENRFIDLogicalSource source = reader.GetSource("Source_0");
    source.SetReadCycle(0);
    reader.addCAENRFIDEventListener(caenrfidEventListener);
    source.SetSelected_EPC_C1G2(CAENRFIDLogicalSourceConstants.EPC_C1G2_All_SELECTED);
    source.EventInventoryTag(new byte[0], (short) 0x0, (short) 0x0, (short) 0x06);

• Stop inventory

   Timber.d("Stop inventory and disconnect reader");
   reader.removeCAENRFIDEventListener(caenrfidEventListener);
   reader.InventoryAbort();

• Disconnect reader when you are done

   reader.Disconnect();
