More details: 
My H4 mode CF card is set in comport 21
When running BluetoothServer I got the message:

HCI: Sending Command: 3075
HCI: Received Command Status Event: 0

I put a debug line under server.run()
try {      
         watchA = hciDriver.send_HCI_HC_Reset();
         BluetoothTCPServer server = new BluetoothTCPServer(2600);
         server.run();
         System.out.println("server is running");
        }catch (HCIException e){
            System.out.println("Can't reset cause of "+e);
        }

obviously may server is not running  
what should i do
Plz!! Chris HELP!!
