Trouble logging OBD2 data

[pmathe...@gmail.com]

Hello,

I having difficulty connecting to my vehicle and logging OBD2 data. The details are below:

Vehicle: Ford Territory SZ MkII (2016 model)

Android device: Samsung Galaxy GT-19300

Android version: 4.3

OpenXC enabler version: 6.1.6

Firmware version:  vi-emulator-firmware-FORDBOARD-ctv7.2.0.bin

                            vi-obd2-firmware-FORDBOARD-ctv7.2.0.bin

OpenXC device ID: 0006666D5630

Issue:

I can successfully establish a bluetooth connection between the phone and VI device when running in 'emulator' mode. The OpenXC Enabler app displays the dummy CAN data without any problems.

When I flash the obd2 firmware and connect to the vehicle I get 2 blue lights on the front of the VI but I get no CAN data whatsoever (vehicle is keyed 'on' and engine running).

I have rolled back the firmware version to 6.0.3, and the Enabler App to 6.0.6 and tried various combinations. The best I can get is vehicle and engine speed messages but the message data is totally incorrect and doesn't update quickly.

Any suggestions would be greatly appreciated!

Many thanks,

Paul.

Hi Paul,

The obd2 firmware simply allows obd2 access. You can send your own requests. Try the translated_obd2 firmware which does automatic recurring requests. This sounds like what you're looking for.

Regards,

Hi Eric,

Thanks very much for the fast reply - the translated_obd2 was indeed what I was after.

It successfully reads engine speed, vehicle speed, coolant temp and % engine load.

Cheers,

Paul.

What about leveraging the Python diagnostic commands?

These appear to respond with the equivalent of a one off OpenXC dump. I'll send associated logs
