Hi,

I have created a USB CDC project using STM32CubeMX. It is running on STM32F429 board. However after receiving first character, the program is not accepting anything. Did anybody face similar problem?Regards,Provat

Hi,

I had the same issue. You have to manually call the receive function again to receive more data:

static int8_t CDC_Receive_HS (uint8_t* Buf, uint32_t *Len){/* USER CODE BEGIN 11 */USBD_CDC_ReceivePacket(hUsbDevice_1);return (USBD_OK);/* USER CODE END 11 */}

Regards,

Robert
