So here we are, released public code for you (if you want) to take this device and repurpose it however you want.
I feel ive done what i wanted with this and to be honest. i have other things that id like to get done. However i will create a OpenSource version of an ODB2 diagnostic tool for this reader at some point. This project has now gone to the "as and when" pile ;)
Its been a great project and fun to learn bits and pieces from it.
Please enjoy the code and as always Feedback is always welcome!
