This memo provides information about how to read CANraw data through the OOBD firmware. Distribution of this memo is unlimited.

(example for HS-CAN setup)

Select the CANraw mode protocol

p 1 1 0 0

This activates the CANraw mode protocol, clears the internal PID list and sets the CAN bus into “invisible listen” mode

Select the HS-CAN interface

p 8 4 0

Select HS-CAN bus speed to 500kbit/s (for other bitrates please have a look to the firmware syntax here: The OOBD Firmware Syntax)

p 8 3 3

Set CAN-Transceiver to normal operating mode

p 8 2 3

Set CAN filter Start address

p 8 10 1 $000

Set CAN filter mask (here: all frames $000 - $7FF are enabled)

p 8 11 1 $000

Activate CANraw listen mode

p 7 1 1

Hint:

If there are already CAN-Messages received on the HS-CAN interface they will be directly transmitted from the firmware to the serial Bluetooth interface so that they are directly accessible by any application (i.e. OOBD-Android). See the chapter Example for more details.

This RFC raises security issues. Sending frames on the bus might create unexpected reactions .
