Has anybody figured out a solution to this message whenever attempting to talk to a VESC via CAN bus? I am working with a VESC 75/300 and can use vesc-tool 6.02 via USB but my vehicle implementation calls for only CAN bus control. I am running two-wire CAN to a DB9 which is connected to a PEAK CAN-to-USB converter connected to my laptop. Using PCAN-View I can see the data dumping from my VESC meaning that I am able to stream data from the VESC but vesc-tool is not able to talk via CAN bus.
I know this is old but maybe it will help someone . I started getting this error when I accidentally changed the can communication in apo settings from “vesc” to “uavcan” and wrote the app . I had to manually connect to it via usb and change the settings back and make sure the baudrate was right then it was working again .

@SuperSpeed Scooter, Were you able to get the two motors run simultaneously using can bus connection with 'vesc' setting? I have been struggling for a few weeks now and I am not able to run the two motors simultaneously over can.

@SuperSpeedScooter,
Are you having this issue on VescTool version 6 ?
I can't seem to find this settings..
I think I am having a similer issue here where I changed the settings to UAVCAN on the ESCs but cannot see them on CANSCAN because the hub is on VESC can protocol. My problem is I have a Vesc Duet, and can only communicate with the hub over USB. If anyone figures out how to change the CAN protocol some other way, Id love to know.
