Class RemoteDeviceHelper

java.lang.Object
  com.intel.bluetooth.RemoteDeviceHelper

public abstract class RemoteDeviceHelper
extends Object

Implementation of RemoteDevice. Instance of RemoteDevice can be created by User. BlueCove should use only RemoteDeviceHelper class to create RemoteDevice instances.

Your application should not use this class directly. The only exception is method authenticate(RemoteDevice device, String passkey).

authenticate

public static boolean authenticate(RemoteDevice device)
                            throws IOException

Attempts to authenticate RemoteDevice. Return false if the stack does not support authentication.

Throws:

IOException

See Also:

RemoteDevice.authenticate()

authenticate

public static boolean authenticate(RemoteDevice device,
                                   String passkey)
                            throws IOException

Sends an authentication request to a remote Bluetooth device. Non JSR-82, Return false if the stack does not support authentication.

PUBLIC JSR-82 extension

Parameters:

device - Remote Device

passkey - A Personal Identification Number (PIN) to be used for device authentication.

Returns:

true if authentication is successful; otherwise false

Throws:

IOException - if there are error during authentication.

authorize

public static boolean authorize(RemoteDevice device,
                                Connection conn)
                         throws IOException

Determines if this RemoteDevice should be allowed to continue to access the local service provided by the Connection.

Throws:

IOException

See Also:

RemoteDevice.authorize(javax.microedition.io.Connection)

encrypt

public static boolean encrypt(RemoteDevice device,
                              Connection conn,
                              boolean on)
                       throws IOException

Attempts to turn encryption on or off for an existing connection.

Throws:

IOException

See Also:

RemoteDevice.encrypt(javax.microedition.io.Connection, boolean)

isAuthenticated

public static boolean isAuthenticated(RemoteDevice device)

Determines if this RemoteDevice has been authenticated.

A device may have been authenticated by this application or another application. Authentication applies to an ACL link between devices and not on a specific L2CAP, RFCOMM, or OBEX connection. Therefore, if authenticate() is performed when an L2CAP connection is made to device A, then isAuthenticated() may return true when tested as part of making an RFCOMM connection to device A.

Returns:

true if this RemoteDevice has previously been authenticated; false if it has not been authenticated or there are no open connections between the local device and this RemoteDevice

isAuthorized

public static boolean isAuthorized(RemoteDevice device,
                                   Connection conn)
                            throws IOException

Throws:

IOException

isEncrypted

public static boolean isEncrypted(RemoteDevice device)

Determines if data exchanges with this RemoteDevice are currently being encrypted.

Encryption may have been previously turned on by this or another application. Encryption applies to an ACL link between devices and not on a specific L2CAP, RFCOMM, or OBEX connection. Therefore, if encrypt() is performed with the on parameter set to true when an L2CAP connection is made to device A, then isEncrypted() may return true when tested as part of making an RFCOMM connection to device A.

Returns:

true if data exchanges with this RemoteDevice are being encrypted; false if they are not being encrypted, or there are no open connections between the local device and this RemoteDevice

isTrustedDevice

public static boolean isTrustedDevice(RemoteDevice device)
