Follow these instructions to set up the raspberry pi to be able to receive files from the app. Almost the entire list of instructions below is thanks to a tutorial on YouTube referenced at https://www.youtube.com/watch?v=DmtJBc229Rg 

One major issue came from the git repository link, which I have fixed below.

• Install Necessary Software on the PI: 

sudo apt-get install python-dev libbluetooth-dev

•  Edit Bluetooth service to flag

sudo nano /lib/system/system/bluetooth.service

• About the 7th line down is:

ExecStar=/usr/lib/bluetooth/blluetoothd 

• add a -C to the end of that line to look like

ExecStart=/usr/lib/bluetooth/blluetoothd -C

• Save, exit and reboot. 
• Run the script to turn Bluetooth on from the command line

bash home/patch/bin/bluetoothOn.sh

•  get pip

cd /home/patch/
wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py
git clone https://github.com/karulis/pytbluez
cd pybluez/
sudo python setup.py install

•  Create Script to enable Bluetooth serial Port

cd /home/patch
sudo nano bluetooth_adv
sudo hciconfig hci0 piscan
sudo sdptool add SP
ctrl-X

•  Give execute permission and run

sudo chmod +x bluetooth_adv
sudo ./bluetooth_adv

•  You're all set-up.
