Valery Gorohovsky & Shmuel Koyas Supervisor: Boaz Mizrachi Spring 2012 Project A Final presentation OBDII_Hack Android Application

 OBD II is the automotive diagnostics standard  Since 2009 CAN is the standard communication protocol in the automotive industry  Our project modified existing firmware.

 An Android application which monitors CAN communication and maps between vehicle devices and their addresses Study CAN protocol Study programming for Android Study firmware programming in Microchip environment Develop a solution for CAN monitoring and data analysis Emphasize both hardware and a software suite on an industry level product

An Android smartphone MobiWize OBDII plug A Car supporting CAN protocol

 Study of the MobiWize firmware  Study the Android SDK  Firmware programming  Application development  Testing  Customer review  Modification and finalizing  Celebrating

Bluetooth initialization and connection to MobiWize

Configuring the plug and sniffing CAN communication

Producing data structures and filtering constant data communication

Changing car inputs and monitoring communication data changes

 Find a suitable car  BT/CAN bandwidth shaping  Synchronizing and enabling Bluetooth communication  Multithread synchronization in Android  Android SDK uses a large and complicated framework  Back up problem – use version control software next time!  Microchip IDE is really not user friendly

 Exporting data and mapping to a database  Synchronizing hack data with server  Adding support for additional OBD protocols  Filtering known headers
