OBDDetect

driving detection and producting

Environment Setting:

Hardware

• 1. Install the Freematics device to car.
• 2. To pair the Freematics with RPi, then run the following command in a terminal: sudo rfcomm bind 0 24:0A:C4:06:50:2A 2 This will bind the Freematics device to /dev/rfcomm0 on channel 2.  
     Afterwards, /dev/rfcomm0 can be read like any serial device. (this step can be run with shell script when pi startup)
• 3. Start OBD run the EventDetect.py
