I bought a rocketfish micro bluetooth adapter (2.1 connectivity). I run Ubuntu 12.04 LTS. My phone runs Android version 4.1.2, and the model is Samsung-SGH-I747, Kernel version 3.0.31-1300972. I didn't know what software info was needed, so this is all I could find.
When I go to connect the devices, they both ask me to put a passkey into the other device, but do not allow me to input anything. My computer won't see the phone until I try to connect to the computer with the phone. Also, the installation cd that came with the adapter won't work.
