1. Start with fresh Jessie install on a Raspberry Pi 2

2. Install some libraries

   $ sudo apt-get install python-pip

   $ sudo pip install pynmea2

3. Change console tty to free up HW UART

   $ sudo nano /boot/cmdline.txt

   Change contents from:

   dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p6 roo tfstype=ext4 elevator=deadline fsck.repair=yes rootwait

   To:

   dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p6 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

   Note: we're removing console=ttyAMA0,115200 from the file.

   You can also achieve this by doing sudo raspi-config, selecting option 8, going to 'Serial' and turning .

4. disable getty on serial

   $ sudo systemctl disable [email protected]

5. reboot the Pi

   $ sudo reboot now
