Question about "btsppEcho" Example - Series60 SDK 0.3.1 - Series60 SDK 2.1

[diplomart]

"btsppEcho" is the Example from the "Introduction To Developing Networked MIDlets Using Bluetooth Version 1.0" from May 11, 2004


I use the following software:
Nokia Dev Suit for J2ME 2.1
Series60 MIDP Concept SDK Beta 0.3.1
Series60 MIDP SDK 2.1 Beta
btsppEcho Example from Nokia

Start Nokia Dev Suit for J2ME -> Start Emulators:
with the Series60 MIDP Concept SDK Beta 0.3.1 (Nokia edition) i get following results:
The btsppEcho Application start select Options -> BTProperties

"my bluetooth address: = 83ad7bf4056f"
"bluetooth.api.version = 10"
"bluetooth.connected.devices.max = 5"
"bluetooth.connected.inquiry = true"
"bluetooth.connected.inquiry.scan = true"
"bluetooth.connected.page = true"
"bluetooth.connected.page.scan = null"
"bluetooth.l2cap.receiveMTU.max = 612"
"bluetooth.master.switch = true"
"bluetooth.sd.attr.retrievable.max = 10"
"bluetooth.sd.trans.max = 10"

So the Device have a BT Address. Everything is fine.
The App. runs an I can Connect to other Devices on the same PC
as well to Devices on other PC over the network.

But if I try to start the btsppEcho Application with the Series60 MIDP SDK 2.1 Beta i got following results:
The btsppEcho Application start select Options -> BTProperties

"bluetooth.api.version = 10"
"bluetooth.connected.devices.max = 7"
"bluetooth.connected.inquiry = false"
"bluetooth.connected.inquiry.scan = false"
"bluetooth.connected.page = false"
"bluetooth.connected.page.scan = false"
"bluetooth.l2cap.receiveMTU.max = 672"
"bluetooth.master.switch = false"
"bluetooth.sd.attr.retrievable.max = 65535"
"bluetooth.sd.trans.max = 1"

So the Device DONT have a BT Address.
Is there any configuration I have to do first to use the
Series60 MIDP SDK 2.1 Beta with this BT Application?
And If I have to do .. were do i have to?

With the (SDK Beta 0.3.1) i can set Preferences -> Bluetooth emulation type:
1. Network using UDP multicastig
2. Single computer using manual port assignment

With the (SDK Beta 2.1) i can't set Preferences for bluetooth emulation!

at the Series_60_MIDP_Concept_SDK_Beta_0_3_1_Nokia_edition\bin Directory i found the "bluetooth.xml" file
were all the configutartion is, but the SDK 2.1 dont have this bluetooth.xml file !

What i have to do to run this MIDlet with the SDK 2.1?

And could i use the UDP Multicasting stuff to develop an App. that
would send and recive data with the emulator over a simulatet bluetooth connection?
