Installing bluehydra on raspberry pi

Introduction

ap BlueHydra is a Bluetooth device discovery service built on top of the bluez library. In this tutorial we are going to give the steps to install bluehydra on the rasperberry pi using Raspbian GNU/Linux 8 (jessie). If you are using raspbien wheezy, please see the Apendix

Installing ruby with rvm

There are several ways to install ruby, the one I prefer is with rvm. rvm is is a command-line tool which allows you to easily install, manage, and work with multiple ruby environments. Download and install rvm with:

 curl -L https://get.rvm.io | bash -s stable --ruby

This will probably raise the error:

 gpg: Can't check signature: public key not found

Read the instructions to download the signatures from the error..

Now let’s check that we are using a correct ruby version:

 rvm current

In the following steps we are going to use blunder to install ruby gems.

 sudo gem install bundler

Now that we have ruby working on the raspberry pi, we are going to install the dependencies.

 sudo apt-get install python-bluez python-dbus sqlite3 bluez-tools ruby-dev bluez bluez-test-scripts python-bluez python-dbus libsqlite3-dev ubertooth

BlueHydra Instalation

 git clone https://github.com/pwnieexpress/blue_hydra.git
 cd blue_hydra
 bundle install

Final Result

sudo ./bin/blue_hydra

If everything is right, you should see the bluehydra working.

if you have a python import error on bluezutils, try to download bluezutils.py and copy it to the bin directory of blue hydra:

 wget https://raw.githubusercontent.com/pauloborges/bluez/master/test/bluezutils.py

Not working in wheezy

When I began writting this tutorial I was using wheezy, but since I got a lot of issues with dbus and errors like:

E, [2016-08-24T00:19:43.606500 #27471] ERROR -- :   File "/home/pi/blue_hydra/bin/test-discovery", line 15, in <module>
E, [2016-08-24T00:19:43.606813 #27471] ERROR -- :     import bluezutils
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "GetManagedObjects" with signature "" on interface "org.freedesktop.DBus.ObjectManager" doesn't exist

To check which version you are using just cat /etc/os-release
