The J2ME Wireless Toolkit allows you to configure the Bluetooth and OBEX
simulation environment. Choose Edit > Preferences... from the KToolbar menu to
see the following window.
FIGURE 38 Bluetooth and OBEX preferences
11.3.1 OBEX Preferences
Devices using IrDA in the real world discover other devices by “listening”. You can
configure how long the J2ME Wireless Toolkit emulator waits to discover another
device using the Discovery timeout fieldintheIrDA OBEX section of the
preferences window. Enter a value in milliseconds.
At the API level, the discovery timeout value determines how long a call to
Connector.open("irdaobex://discover...") will block before it returns or
throws an exception.
The maximum packet length affects how much data is sent in each packet between
emulators. Shorter packet values will result in more packets and more packet
overhead.
