Freematic OBD-II I2C ISO 15765-4

Post by Harvey68 »

Hello,

i bought last year the Freematic OBD-II I2C but did'nt look what protocols my car needs:

I have a Nissan X-Trail T31 2.0 150HP, it uses ISO 15765-4 CAN (11 bit ID,500 Kbaud), but the Freematics OBD-II I2C Adapter (for Arduino) has not this protocol?

On the website is written:
Vehicles using following vehicle protocols are supported.

CAN 500Kbps/29bit
CAN 250Kbps/29bit
KWP2000 Fast
KWP2000 5Kbps

So it is possible to use the 15765-4 protocol or not?

Or is the problem the I2C? Not fast enough for the 500 Kbaud?

yours

The OBD-II I2C adapter works on some 11-bit CAN bus but not all so we don't list that as supported protocol. The OBD-II UART (V1 and V2) work with 11-bit without any issue.
