arduino Nano + rn-42 bluetooth module, connected but not work

Hello, thanks to take 5 minutes to read this post.

I'm doing a project consisting of a temperature sensor, it will be read by arduino and sent from the bluetooth module. I downloaded the APP BlueTerm to look the results from bluetooth module and my smartphone.

The module is connected from rx to arduino tx, and module from tx to arduino's rx. The device is powered at 3.3v

I managed to connect the smartphone with the bluetooth device but not transmits anything to the termnal, i can conect but i can't read results.

I had been testing the baudrate and other bluetooth applications, the module having antenna, I have been testing with delays also .. but i can't find the solution.

Solutions?

Thanks.

It is more for the JY-MCU, but one bluetooth is much the same as another.
