Hi, I accidentally encountered a problem with echo-received packets after transmitting. Is there a software initialization of FDCAN way to avoid it? I can't use a filter 'cause receiving the packet for MCU is possible.

Sounds like you have your Mode set for External Loopback mode instead or Normal Mode.

Check MX_FDCAN1_Init function to see what Mode you're using.
