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 verison of Bluez you do not need to do this step!
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 this step.
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
You may need to type the above code in to make it work rather than doing a copy/paste, or manually remove a superfluous line feed between lines
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
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.
