bluetooth UUID search with Java / bluecove

Question

In windows, I communicate fine with my bluetooth connected devices. I get the name and address of the device ok. But, the line

UUID[] uuids = device.getUUIDs();

… produces this error:

The method getUUIDs() is undefined for the type RemoteDevice

Code sample

import javax.bluetooth.DiscoveryAgent;
import javax.bluetooth.LocalDevice;
import javax.bluetooth.RemoteDevice;
import javax.bluetooth.UUID;
//...
LocalDevice localDevice = LocalDevice.getLocalDevice();
DiscoveryAgent discoveryAgent = localDevice.getDiscoveryAgent();
RemoteDevice[] devices = discoveryAgent.retrieveDevices(DiscoveryAgent.PREKNOWN);
UUID[] uuids = device.getUUIDs();

Answer 1

According to the documentation, the RemoteDevice class does not have a getUUIDs() method. I assume that in your code the device is a single member of the devices array, otherwise there might still be an error in your code.

Answer 2

As already pointed out by others, there is no getUUID() method in RemoteDevice class. However, if you need the bluetooth address you can use the getBluetoothAddress() method like this:

package org.example;

import javax.bluetooth.DiscoveryAgent;
import javax.bluetooth.LocalDevice;
import javax.bluetooth.RemoteDevice;
import java.io.IOException;

public class BlueTest {
    public static void main(String[] args) throws IOException {
        LocalDevice localDevice = LocalDevice.getLocalDevice();
        DiscoveryAgent discoveryAgent = localDevice.getDiscoveryAgent();
        RemoteDevice[] devices = discoveryAgent.retrieveDevices(DiscoveryAgent.PREKNOWN);
        for (RemoteDevice device : devices) {
            System.out.println("Address: " + device.getBluetoothAddress());
            System.out.println("Name: " + device.getFriendlyName(false));
        }
    }
}

Hope this helps.
