receiving data from arduino (HC-06 module) to android phone via bluetooth.

[Slully]

I want to receive data from arduino (HC-06 module) to android phone via bluetooth. I want to make an application in Qt to receive data, but I dont know, which library should I use to do it. I was trying to run Qt Chat bt example, but it did not find my arduino. Can you please give me some examples, or tips, what should I do step by step?
Thank you.
