In order to use your Raspberry Pi to send out Beacon data in the advertising frame, we'll need to install a few open source tools, mainly Bluez

Check if you already have Bluez

If you already have a modern version of Bluez you do not need to compile and can skip to step 4!

On your Raspberry Pi, try running

sudo apt-get install bluez

and then

dpkg --status bluez | grep '^Version:'

If you get something like Version: 5.23-2+rpi2
Where the version is greater than 5.11 you can skip the installation and compilation steps.

1. Install Required Libraries

sudo apt-get install libusb-dev libdbus-1-dev libglib2.0-dev libudev-dev
sudo apt-get install libical-dev
sudo apt-get install libreadline-dev

sudo apt-get install libusb-dev libdbus-1-dev libglib2.0-dev libudev-dev
sudo apt-get install libical-dev
sudo apt-get install libreadline-dev

2. Download Bluez

sudo mkdir bluez
cd bluez
sudo wget www.kernel.org/pub/linux/bluetooth/bluez-5.11.tar.xz

sudo mkdir bluez
cd bluez
sudo wget www.kernel.org/pub/linux/bluetooth/bluez-5.11.tar.xz

3. Unzip and Compile Bluez

Next you need to actually build Bluez on the Pi. This step may take a while, but should work without any hiccups if you properly installed all the libraries in step one above:

      sudo unxz bluez-5.11.tar.xz
sudo tar xvf bluez-5.11.tar
cd bluez-5.11
sudo ./configure --disable-systemd
sudo make
sudo make install
    

      sudo unxz bluez-5.11.tar.xz
sudo tar xvf bluez-5.11.tar
cd bluez-5.11
sudo ./configure --disable-systemd
sudo make
sudo make install
    

4. Insert the USB Module and Reset

Once Bluez has been built, shut down your computer with sudo shutdown -h now and once its Halted, insert your Bluetooth 4.0 USB Module and then restart the Raspberry Pi so that all of the changes we have made can take effect.
