   2. change ExecStart=/usr/lib/bluetooth/bluetoothd into ExecStart=/usr/lib/bluetooth/bluetoothd -C
   3. sudo sdptool add SP

9. Clone RFCOMM server into some folder git clone https://github.com/dinohorvat/pybluez--rfcomm-server.git

10. Install Pybluez

    1. sudo apt-get install bluetooth libbluetooth-dev
    2. sudo pip install pybluez

11. Making the script run on boot

    1. sudo nano /etc/rc.local
    2. Added this before the exit line (bottom of the script) sudo bash -c 'python /YOUR-PATH/rfcomm-server.py > /YOUR-PATH/rfcomm-server.log 2>&1' &
