Simply, these bluetooth modules are not tolerant to signal levels of greater than 3.3V. The Arduino output signal levels are true logic at 5V. Many people on forums argue that you can run these devices at signal levels of 5V, but I have experience of serious degradation to the module and unstable bluetooth connections directly attributed to running the signals at 5V.
There are many places that show a divider network to limit the Arduino TX out to the Bluetooth module RX in. Well, I have created a very simple PCB that does it for you:
The Bluetooth module Tx to Arduino RX signal does not require conditioning as it is generated by the module at 3.3V. The rest of the signals on the pcb are straight through, En to En, ST to ST, Vcc, Gnd and Arduino Rx to Bluetooth TX. Please check in picture 3 that your pin outs match those of the module shown.
