I feel like this is something RealDash problem because at CAN Monitor it works. Sometimes timeouts…

If not sending anything for a while:

on the main dash still getting

Looks like RealDash have timout problem.

[realdashdev]

Timeout is normal when there is no data from CAN bus for a few seconds.

Don’t know really what the problem could be. We use Seeedstudio CAN adapter on 2M baud on Windows and Linux daily with no issues.

I think it works but gives me bad information. Connecting to /dev/ttyUSB0 (interface) is not same as Waiting Canbus data. I thought there is problem with the interface but not. It’s just waiting for Canbus message.
