FDCAN not receive messages from a few particular sensors

[Ping1]

Dear all

I am using STM32H563 and interface with some CAN bus sensors to receive and sometimes send data to them. The CAN bus sensors are developed by a partner company. I developed my software refer to FDCAN_Com_IT example provided in IDE firmware package. They work fine most of time, but there is an issue has been bother me - for a few sensors, tmy software doesn't receive the message form them, it doesn't generate interrupt simply.  Don't think the sensor module is fault as they can be received by a CANUSB dongle, it seems the issues are with a few fixed sensor modules only, so i am wonder what I have done wrong to miss the message, on Logic analyser, message can be seen although sometimes it is with error, but most of time, they are fine, just doesn't reach my ISR.

Regards!

Try:

  FDCAN_FilterTypeDef        sFilterConfig;
  sFilterConfig.IdType       = FDCAN_STANDARD_ID;
  sFilterConfig.FilterIndex  = 0U;
  sFilterConfig.FilterType   = FDCAN_FILTER_MASK;
  sFilterConfig.FilterConfig = FDCAN_FILTER_TO_RXFIFO0;
  sFilterConfig.FilterID1    = 0;
  sFilterConfig.FilterID2    = 0;
