bluetooth with matlab

sh63:
I am willing to communicate between arduino and matlab via Bluetooth hc-06 module. The problem is it seems that I can not send any thing from matlab to arduino properly. However the status of Bluetooth object is open and the number of " ValuesSent " is showing that I am sending data but in Arduino site, the Serial.available() is always "0"!!! I am wandering it might be hardware issue!! Could you please help me to solve this?

Thanks

Most of us don't have Matlab.
