Is it possible to communicate between two ESP32 without CAN transceiver?

[rahullabs]

I have two ESP32-VROOM-32 and I want to connect these two ESP32 with wire. I know its possible through the CAN transceivers but I want to connect without a CAN transceiver. If it is possible is there any schematics or code that I can get a reference from?

Also, I know it is possible to communicate between these two devices through Bluetooth and Wifi but my boss wants it through the wire without a CAN transceiver. So I have no other option.

I don't think so... not that familiar with CAN, but one of the features of the transceivers is to help in collision detection, which even with two devices may be an issue. Can you use UART instead? It's pretty easy to hook that up without a transceiver.
