Are you using software serial for the BT module? Is your arduino powered with USB lead or power connector? What code are you using to read/write to PC over BT module (remember to post any code between code tags)

Code is working fine with normal arduino Serial Communication thru FTL 232 (onboard USb-Serial) . I am using NANO.

But when it comes on Bluetooth module , Data sent from Arduino is recived on PC thru Bluetooth .... But no data is sent to Arduino from PC thru Bluetooth Module


Try using software serial to send/receive from BT module to see it that works. I never had much luck trying to connect BT modules to UART RX/TX pins when powered over USB, I think the FTL232 interferes.
