11.3.2 Bluetooth Discovery Timeout
In the Bluetooth section of the preferences window, the Device discovery timeout
is the amount of time, in milliseconds, the emulator will wait while attempting to
locate other devices in the simulated Bluetooth environment.
11.3.3 Bluetooth System Properties
The System Properties tab in the Bluetooth section of the preferences contains
properties that can be retrieved in an application using the getProperty()
method in javax.bluetooth.LocalDevice.
The Bluetooth properties are fully described in the JSR 82 specification.
11.3.4 Bluetooth BCC Properties
The Bluetooth Control Center (BCC) controls Bluetooth settings. Some devices may
provide a GUI to customize Bluetooth settings. In the J2ME Wireless Toolkit, the
BCC is configured using the BCC Properties tab of the Bluetooth preferences. The
properties are as follows:
TABLE 7 BCC properties
Property Description
Enable Bluetooth
support
If this property is disabled, then
LocalDevice.getLocalDevice() throws a
BluetoothStateException and no connections can be created.
This is useful to test the behavior of your application on devices
that support JSR 82 but may have the Bluetooth feature turned off.
Device is
discoverable
This property indicates whether or not this emulator can be
discovered by other emulators.
Friendly name The friendly name is a human-readable name for the emulator in
the simulated Bluetooth environment. If the name is left blank, the
emulator will not support the “friendly name” feature.
Encryption This property determines whether connection encryption is
supported (on) or not (off). In addition, the force settings means
all connected must be encrypted. See the documentation for
RemoteDevice’s encrypt() method for details.
Authorization This is similar to the Encryption property. See RemoteDevice’s
authorize() method.
Authentication This is similar to Encryption and Authorization. See
RemoteDevice’s authenticate() method.
