Android application Bluetooth connect to device receive streamed data

Hello, I need an Android app, i think this should be easy enough. Goes like this. 1. App connects to a Serial Bluetooth device (think arduino like). 2. App should be able to handle the bluetooth stuff by itself, buttons in the main activity: pair/connect/disconnect/list devices. 3. Once connected it should move into a new page/activity where a Start button once clicked it will start to receive 129 double values streamed through bluetooth from the paired device . 4. Once all values are received it should list them with spaces between them. It should be able to do this continuously and after every 129 (1+128) values it should add an end marker and start the new line. We will stop here for now. From here the app will go into calculating the FFT of the F1 only not the DC in complex, calculate the phase and amplitude and store it in a database with 6 columns (ID, 1'st value sent from the 129, real part of FFT, imaginary part of FFT, amplitude and phase). From there it will go into some small graphics. For starters i would like to have just the bluetooth connect stuff and a page that prints what I send using a terminal BT software from my PC/Win7.
