REV Hardware Client: CAN Bus error

Hi! I was trying to configure the robot and this message popped up.

I double checked the wiring and I replaced damaged CAN wire.
Please help!

Thank you,
Stephen.

Did it just pop up once, or is it a recurring problem? If you reboot the robot and hardware client, does it still appear? If it’s still appearing, does the timestamp change or is it always the same?

I rebooted the robot and hardware client and it still appears. The timestamp did change.
Additionally, when I plug the USB-C cable in to configure the controllers, they started blinking red - yellow (brushed motors) and red - cyan (brushless motors).

Thank you.

I don’t see red/yellow or red/cyan listed as defined blink codes, which makes me think its either a combination of codes or the “red” you describe is actually orange (which would be valid fault codes)

Are all your CAN devices showing up in the list?
