Bluetooth connection closed

[barak]

Hi, everyone,

I used JBuilder to develop J2ME application, running on Nokia 6230,
communicate to Bluetooth device. The discover device and services goes fine
and finally the connection command look like
btConnection = (StreamConnection)Connector.open(
"btspp://00E098C0F053:1;authenticate=false;encrypt=false;master=false");
The connection opened and function for about one second then closed.
Any idea why the connection closed?

Thanks in advanced
