Hello @JACK00 ,

In next time, could you please describe your issue in English as other community members can help you?

Translation:

"The CAN communication between the main control board (SMT32F407VGT6) and the server board (STM32F407VGT6), the ambient temperature is lower than -10 degrees, the communication is abnormal, and the ambient temperature is higher than -10 degrees!"

Not sure the question is clear. Could you please elaborate more?

The CAN communication between the main control board (SMT32F407VGT6) and the same server board (STM32F407VGT6) shows that the ambient temperature is below -10 degrees, the communication is abnormal, and the ambient temperature is above -10 degrees! Immediately returning to normal, may I ask what the reason is? Confirm that the CAN communication interface hardware chip meets the requirements!
