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.
