I''m using bluesmirf module + arduino nano to send data to the PC and visualize them.

I have one major problem with the bluesmirf is that it is causing a lot of noises, and they interfere with our algorithm.
I have attached the screenshot of our system when using bluesmirf (noises.png), and when using USB Cable (no_noise.png). Im sorry that I cant capture the scale, but the range of the signals are 0-5V.

I'm not connecting CTS and RTS (flow control) together. Even doing so doesn't help.

Is there anyway I could fix the problem? Thanks
