Real Time Car tracking now working!
At long last I have found a way to track my car in real time. The cool thing is I can also track my car from one car to another :cool:
Bluetooth link to my mobile phone (although a cable would work just as well)
GPRS capable mobile phone with a data enabled SIM card and contract.
Lantronix Com Port Redirector
KeepRAS (Internet link keep alive software)
And here is what I did:
Firstly, I configured my mobile phone for internet access, this was probably the hardest bit due to figuring out the best way to configure the bluetooth connection. I happen to be using a Lynksys Bluetooth dongle to a SonyEricsson p900.
Next step was to configure a VPN link to my home server. I needed to do this as it's not possible to access my car PC through the internet from home directly. When the VPN link is up and running I can communicate to my car PC just as though it was sitting next to me in my home LAN. Also, this makes things that bit more secure.
Next was to figure a way to get the serial data from my GPS unit from the car to my home server. For this I used a combination of Comfoolery and Lantronix com port redirector. Comfoolery takes your com port and makes it available through an ip address and port number. The Lantronix software is able to take a local com port and send it to a remote ip address.
You with me so far?
I installed the Comfoolery software on my car PC to provide a car based ip com port. I then installed the Lantronix software on both my car pc and home server. This allows me to provide local comports on both the car pc and home server providing GPS data. This is important as I need a GPS signal in the car for my navigation software and also a GPS signal at home for my tracking software. Simply configure your mapping and navigation software to the com port that Lantronix provides.
Lastly, I used KeepRAS to open the internet connection and VPN connection automatically in the car and also to re-establish the links should they drop. Now all I need to do is start the car and drive off, the car can be tracked from home in real time.
