Turn the Raspberry Pi Into a Bluetooth Device That Is Discoverable by Remote Bluetooth Client

Introduction

I have a Bluetooth Radio USB device that was gathering dust when I stumbled upon it. So I thought I should put it to use with Raspberry Pi. This instructable is about my learning journey of adding a bluetooth interface to Raspberry Pi.

Target Readers

This instructable will mostly benefit Linux users, especially Debian and its derivatives like Raspberry Pi running Raspbian OS.

System Environment

Raspberry Pi with the following specification:

Model B
Debian 7.6
Bluetooth Radio USB Adaptor
Mains-Powered USB Hub

Scope

This instructable will cover the following:

Install and run Bluetooth in Raspberry Pi.
Make Raspberry Pi discoverable by remote bluetooth client.
Test for success by using a remote bluetooth client that can show that it has discovered the Raspberry Pi device.

This instructable will NOT cover the useful things that can be done by a Raspberry Pi with a bluetooth interface. In other words, although I have turned the Raspberry Pi into a Bluetooth device, I did not show any useful task that can be done with a Raspberry Pi that has a bluetooth interface. Read my "Send a copy of your photos and videos in your Android Phone to Raspberry Pi using Bluetooth" instructable if you are interested to do useful stuff with the Raspberry Pi.
