Problem of transmitting data from serial device to bluetooth on Arduino

I am using an accelerometer which uses serial communication on Arduino (UART), I wish to transmit the data to a bluetooth module (blusmirf gold) using I2C and finally read it from my android application.

I am able to detect the correct reading from accelerometer, I am also able to transmit the data through bluetooth. However, when i put these two things together, it only transmit once and stop transmitting anything afterwards.

Is there anyone can help me with this? Thanks in advance!
