STM32F2xx detect CAN speed mismatch when receiving data

Question asked by ice111 on Dec 8, 2014
I am using STM32F2xx, and CAN1. I using NVID for the CAN data

I have configured my firmware to receive CAN data at 1Mbps, but how can I detect if the receive CAN speed rate is not 1Mbps? so I can display in my LED that the CAN speed is different

Ex: I cant get any CAN data event in the interupt at 500kbps, is there anyway I can get the CAN speed mismatch event?
