Problem using OBD-II UART Adapter

[basrad]

Hello all, Merry Christmas if you're celebrating.

I was very excited to receive my connector and very pleased at how fast it was delivered over the holidays.

Unfortunately, I'm getting in a bit of a tizz following links around trying to get some functionality.

I have an UNO, an OLED 128 x 64 an a brand new OBD-II Uart Adapter. It says for Arduino on it, but I can't see a version number anywhere. It should be the V1.

I am unable to get any communications with the device. I tried serval example sketches and the nanoscanner. My screen works fine, but no data is returned from the adapter. The UART adapter is plugged into Pins 0 and 1 of the UNO - Does this means I get not serial debugging? The code wont upload while the adapter is connected to the arduino.

I've tried the RPM LED example, nothing.. I've tried the most basic "ODB is connecting" on OLED. It never moves onto "CONNECTED"

My car is a VW T5 using KWP2000 Fast and KWP2000 5Kbps. Does this need setting up in the UARTODB.h?

Any advice to getting a data return would be fantastic.

Kind Regards

Try modifying the code of obd.init() and add the protocol so it is like:

obd.init(PROTO_KWP2000_5KBPS)

or

obd.init(PROTO_KWP2000_FAST)
