cannot detect bluetooth device...

Hi,
Erm I used 115200 for baud rate, the parity, stop bit and flow control as the manual shows. It didn't work. Then I tried 9600 baud rates, it is works. is it I'm wrong??
But, when i try connect the skkca with bluetooth dongle, but it failed to detect each other...
and when the bluesoil is launch, it shows INVALID Operation.
so what is the problem??
