Sample Application for ASK UCM108 RFID reader

Introduction

This sample application illustrates how to use the ASK UCM108 RFID reader on Coppernic devices.

The libraries

Coppernic uses a Maven repository to provide libraries.

In the build.gradle, at project level, add the following lines:

allprojects {
    repositories {                
        maven { url "https://nexus.coppernic.fr/repository/libs-release" }
    }
}

Documentation

The javadoc for CpcAsk can be found here.

The basics

Power management

Libraries

CpcCore is the library responsible for power management.

In your build.gradle file, at module level, add the following lines:

implementation 'fr.coppernic.sdk.core:CpcCore:2.1.12'

Power on/off RFID reader

First, implement PowerNotifier:

public class MainActivity extends AppCompatActivity implements PowerListener

...

@Override
public void onPowerUp(CpcResult.RESULT result, Peripheral peripheral) {
	// reader instantiation
	Reader.getInstance(this, this);
}

@Override
public void onPowerDown(CpcResult.RESULT result, Peripheral peripheral) {
	enableUiAfterReaderInstantiation(false);
}

Then register it in Power API, in onCreate for example:

PowerManager.get().registerListener(this);

Use the on/off methods:

if (isChecked) {
    if (OsHelper.isAccess()) {
        AccessPeripheral.RFID_ASK_UCM108_GPIO.on(MainActivity.this);
    } else {
        ConePeripheral.RFID_ASK_UCM108_GPIO.on(MainActivity.this);
    }

} else {
    if (OsHelper.isAccess()) {
         AccessPeripheral.RFID_ASK_UCM108_GPIO.off(MainActivity.this);
    } else {
         ConePeripheral.RFID_ASK_UCM108_GPIO.off(MainActivity.this);
    }
}

Finally, release it:

PowerManager.get().unregisterAll();
PowerManager.get().releaseResources();

Reader initialization

Libraries

CpcAsk manages the ASK UCM108 RFID reader:

implementation 'fr.coppernic.sdk.ask:CpcAsk:4.0.2'

Create reader object

First declare a Reader object:

private Reader reader;

Then instantiate it:

Reader.getInstance(this, this);

Where your activity implements InstanceListener:

@Override
public void onCreated(Reader reader) {
    this.reader = reader;    
}

@Override
public void onDisposed(Reader reader) {

}

Open reader

On a C-One and Access-ER ASK, by default baudrate is 115200 bauds:

reader.cscOpen(ASK_READER_PORT, 115200, false);

Get firmware version to initialize reader for communication

StringBuilder sb = new StringBuilder();
reader.cscVersionCsc(sb);

Reader is fully initialized.
