i have played with the Tutorial "Introduction_To_Developing_Networked_MIDlets_Using_Bluetooth_v1_0.zip" and special with the "btsppEcho " example. In the emulator is the connection between ServerClient...no problem. But it is possible a connection between the application on the NOK6230 and the PC/Emulator, or stil beter in reaction of a signal from the NOK6230 (like click button 5) directly into Jbuilder or Eclipse! For example click on NOK6230, the response is a "change of state" from a boolean(True to False.)
