Hi, If the led is not blink, that means It doesn’t get any message.
I think you could double check this 2 things:
- does the CAN_H and CAN_L connect right?
- does the baudrate set right? I mean if the baud rate of your CAR is 100k?
One more thing, the latest code is here: github.com/Seeed-Studio/CAN_BUS_Shield
