What happens if the transmit ID and receive ID are the same in CAN?

[takagi_y]

RT1062 When the transmit ID and receive ID are the same value in CAN, the transmitted data is received on the channel it was sent on.

I have a question because there is an error in the settings.

I have confirmed that the LPB of FLEXCANx_CTRL1 is 0.

Best regards

Hello @takagi_y,

Due to the behavior of the protocol the transmitter is always listening to the bus, but you can disable the self-reception in the bit "SRX_DIS" of register "Module Configuration Register (FLEXCANx_MCR)" in the RM, where inside describes the bit functionality.
