ESP32 - ESP32 CAN communication issue using SN65HVD230 transceiver

[bnvarma]

Hello,

I am currently working on CAN communication between two ESP32 boards and need some guidance.

Hardware details:

ESP32 boards :2
CAN transceiver: SN65HVD230
Number of CAN nodes: 2

I want to establish bidirectional CAN communication between the two ESP32 devices:

ESP32-A should transmit CAN messages to ESP32-B.
ESP32-B should receive the messages and send responses back to ESP32-A.

Current issue:
I am unable to successfully transmit or receive CAN messages between the two ESP32 boards. I have checked the wiring, but communication is not working as expected.

Could anyone please guide me on the correct configuration or share a working example code for ESP32 CAN communication using the SN65HVD230 transceiver?

Any help regarding wiring, CAN driver configuration, termination resistor setup, or sample code would be greatly appreciated.

Thank you.
