ISO baud rate command support with UART Adapter

Post by jcheairs »

Hi everyone. I have the OBD-II UART Adapter V2.1 and I cannot seem to use the AT IB command. When I attempt to do so I get back a '?' response from the adapter, which I think means it does not support it. Reference for the command is here (https://www.sparkfun.com/datasheets/Wid ... mmands.pdf), but the long and short of it is that I need to change the baud rate for KWP (fast int) - protocol #5. The reason for this is that it seems toyota decided to send tpms data via a different protocol than the other sensor data. Further they decided to send it at 9600 baud, which is not the standard speed for the protocol. Can this adapter support the AT IB commands?

Thank you

ATIB command is not supported. Use ATSP to set a protocol.
