How to send anything from Edison's Arduino IDE to android phone via bluetooth?

Hello all,

I have manged to receive data on my Edison board (on arduino IDE) from an android phone successfully following this tutorial Communicate to Arduino code with your Android* Phone by Bluetooth Serial Port Profile (SPP) on Intel® Edison , but now I need to be able to send even a string from my Edison (via arduino IDE) back to the android phone via Bluetooth, I have searched a lot but can't find an answer.

Thanks in advance
