Thank you for your answer. I didn't understand it well before. I'm sorry.Now I have found the reason after many attempts: the uint32_t const pointer type used in routine transmission, and the uint8_t const pointer type used by me, the length transmission should be divided by 4, the length transmission was wrong before, three times more transmission resulted in noise, now it has been solved,thank you all the same.
