First connect low speed. Then highspeed.
??
I can't follow you.
High speed is only on obd and low speed on nac itself.
Low speed doesn't work on obd and high speed doesn't work on nac directly.
What did you do?
Or you could test my sketch, it has a built-in settings for changing bitrate and speed.
You can also save the values directly in arduino.
All accessible via console.
Also some other nice features, see description.
The only thing that oesn't work yet is sending multiframes.
Reading single- and multiframes works and sending single frames works.
Unfortunately I haven't found the time to finish the sketch yet.
But it's pretty useful for logging.
