Use the [PyUAVCAN](https://pyuavcan.readthedocs.io/) CLI tool. We’ve got a couple of examples published in the crash course, too:

> $ pyuavcan pub 4919.my_project.MyMessageType.1.0 '{value: 1234, key: "Hello world!"}' --tr='CAN(can.media.socketcan.SocketCANMedia("vcan2",8),59)'
> 
> ```

The tool works on any platform but the CAN transport is currently only supported on GNU/Linux because it supports only SocketCAN as the backend. If you would like to use CAN on a different platform, please help us resolve this:
