When I use the V4 Datalogger with K-Line protocol, there is never GPS and OBD output in one file. Sometimes only GPS and ACC Data, sometimes only OBD-Data, never both in one file. (I cannot say, when it records GPS/ACC and when only OBD, mysterious.. ) At CAN protocol everything is fine. Any ideas?

I think if you don't change the code, its the fastest method. If you want to slow it down or set a frequency, it works with delays in the loop. But setting a frequency would be also very interesting for me, so I ask, if someone has a idea for implementing it. Biggest problem should be, that CAN is m...

Hey guys, has anyone of you made the V3 Datalogger work for any other protocols than CAN11/500? (Other CANs or K-Line..?) I unfortunately could not and I'm wondering if the problem is in the open source code (OBD.cpp) or in the non-open source code from the STM32-Interpreterchip. I already tried to ...

Thanks for your answer.
As you said, I downloaded Arduino from arduino.org. I still have the same error while uploading.

Any other suggestions?

Hi guys, when I try to upload my code or any other code to my new Vehicle V4 Datalogger, I'm always getting the error, which says: "avrdude: verification error, first mismatch at byte 0x000 0x62 != 0x0c ..." Bildschirmfoto 2016-05-24 um 19.01.44.png I already tried different computers, sta...

Have you solved the problem yet?
I ordered the V4 Datalogger today and my CSV Output looks nearly the same as yours.

Thanks in advance

I have a question.
Does the V4 Datalogger device work with the Firmware Code from Stanley?

Im sitting here with the V3 Datalogger and cannot make it work. So Im thinking about ordering the next generation.

Thanks in advance.

Hello guys, this is, what I got from a trip, longer than an hour. I uploaded the latest V3 Firmware Code on the V3 Datalogger via Arduino as ISP. My testing car was VW Golf VI 1.4, I think OBD communication was via K-Line. As I see on the file size of 2KB, connection got lost during the trip. Does a...
