Network Setup

Once your Pi is physically ready to be installed in your car there are a few things that need to be worked out. Since OnBoardPi uses a web-server to push OBD data to connected devices, you will need some sort of LAN within your car. We have a few options:

1. You have an Android car stereo or a vehicle with a WiFi hotspot. This method does not take any more setup than the Pi and the software itself, just connect your Pi to the existing network and you are good to go.
2. Use your phone's cellular hotspot. At the moment, OnBoardPi does not require any internet connection so it will not use your data plan. Set up your personal hotspot on your phone and connect the Pi open a browser and go to http://raspberrypi.local. If you cant reach the host you will need to know the IP address of the Pi for this method to work so use an app like Network Analyzer to scan for devices connected to the hotspot. Further you can configure the Pi to have a static IP on ths hotspot so you do not have to scan for it each time. This option will be handy in the future when OnBoardPi supports cloud backups so it can use a cellular plan for internet access.
3. Use the Pi itself as a wireless hotspot. I use Autohotspot which allows you to configure the Pi to connect to any known network within range and fallback to being a hotspot. So when you are parked at home in your router's range, the Pi can have internet access, but if you are driving around the Pi will create its own network allowing you to access the OnBoardPi web page.
