Sample Code

USB Scanner​

Detect the Connected Devices List​

var usbDeviceManager: DatalogicDeviceManager

usbDeviceManager.detectDevice(context) { devices ->
                _deviceList.postValue(ArrayList(devices))
}

Open the connected device and setup the scan listener to get the barcode scanning data​

// Open the device
val result = device.openDevice(context)

when (result) {
USBConstants.SUCCESS -> {
                       	 //Setup listener
            		scanEvent = object : UsbScanListener {
			//The onScan() function will be called when scanner scan the barcode
                			override fun onScan(scanData: UsbScanData) {
                    			setScannedData(scanData)
                                       }
               		  }
          }                
}

Bluetooth Scanner​

Steps to pair the Bluetooth Scanner with SPP profile​

var usbDeviceManager: DatalogicDeviceManager

// Create the barcode image to pair scanner
val bitmap = usbDeviceManager.qrCodeGenerator(context, BluetoothProfile.SPP)

// Start to pair the Bluetooth scanner
usbDeviceManager.stopScanBluetoothDevices(context)
usbDeviceManager.scanBluetoothDevices(context) { pairingData ->
    val status = pairingData.pairingStatus
    val message = pairingData.message
    val name = pairingData.deviceName
    
    when (status) {
        BluetoothPairingStatus.Successful -> {
            if (message.contains("connected")) {
                setPairingStatus(PairingStatus.Connected)
            } else {
                setPairingStatus(PairingStatus.Paired)
            }
        }
        BluetoothPairingStatus.Unsuccessful -> {
            if (message == "Permission denied") {
                setPairingStatus(PairingStatus.PermissionDenied)
            } else {
                setPairingStatus(PairingStatus.Error)
            }
        }
        BluetoothPairingStatus.Timeout -> {
            setPairingStatus(PairingStatus.Timeout)
        }
    }
}

// We need to scan the bitmap image with Bluetooth scanner here…

// Remove Bluetooth device scanning setup
usbDeviceManager.stopScanBluetoothDevices(context)

Steps to connect the Bluetooth Scanner to receive scanning data​

// Create the scanning listener 
bluetoothScanEvent = object : UsbScanListener {
    override fun onScan(scanData: UsbScanData) {
        setScannedData(scanData)
    }
}

// Connect the Bluetooth scanner 
CoroutineScope(Dispatchers.IO).launch {
    device.connectDevice(bluetoothScanEvent, context) { status ->
        if (status == BluetoothPairingStatus.Successful) {
            _status.postValue(DeviceStatus.OPENED)
            _deviceStatus.postValue("Device opened")
        } else {
            _status.postValue(DeviceStatus.CLOSED)
            _deviceStatus.postValue("No device selected")
        }
    }
}

// When the scanner scan barcode, the scanning data should be returned on bluetoothScanEvent
//…

// Disconnect the Bluetooth scanner
device .clearConnection(context)
