When I connect the dashboard, these are the results with the loop message and with a total resistance about 55ohms:
The signal at the osciloscope stays with the noise of that mensage. It looks like it added the noise of the message to the typical CAN signal that the dashboard has.
when i try to run the receive_can stub with these settings, i detect the signal on the oscilloscope but i still don't receive anything on the Serial Monitor. Just this message:
