Hi! 

On 1st board i use HAL_UART_Transmit(&huart3,send_arr,100,5000); to transmit send_arr to 2nd board. on 2 nd board, i use HAL_UART_Receive_IT(&huart2,rec_arr,100); to receive data from 1st. but, If the data is lost , HAL_UART_Receive_IT(&huart2,rec_arr,100); do not callback. Does my program stopping until the rec_acc have enough 100 element?
