In addition you will need to set up bluetooth communication, I used the begining of this tutorial to set it up but the TL:DR is:
First: install the packages needed
sudo apt-get install bluetooth blueman bluez
sudo apt-get install python-bluetooth
Second: pair your mobile device
sudo bluetoothctl
[bluetooth]# power on
[bluetooth]# agent on
[bluetooth]# discoverable on
[bluetooth]# pairable on
[bluetooth]# scan on
pair <mac address of your phone>
In addition you'll need a way to communicate to the pu via bluetooth. I found that bluetooth terminal apps for your smart phone a very easy way to do this.
