Hi,I try to comuunicate between STM32L443VCT6 and ultrasonic A02YYUW (By UART1) Just to make sure that the ultrasonic is working ok, i tested it by UART1 with model: stm32 neucler f441 and everthing works ok. This is the code for the STM32L443VCT6: ...

Of course, I received the data, For example it fail just 1 in 10 times. but i can know when it fail. i double check each value in the data

It looks like that sometime not all the data in the array comes: HAL_UART_Receive(&huart1, &data[i], 1, HAL_MAX_DELAY); and then this prevent from the code continue to run..

Thank Everyone for you fast response,I Solved it, i do not understand why..., but the "HAL_MAX_DELAY" blocked the receiveing data, So i modify it to 300ms and now i get response from the ultrasonic, There is a tiny glitch, that seldom. the sensor not...
