Question
After the new firmware package for STM32WB, v1.2, I am not able to see the STM32WB on COM port after running a simple USB CDC code to enable serial communication.
//main.c file

char dataOut[256];
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
sprintf(dataOut, "HelloWorld");
//CDC_Transmit_FS(( uint8_t * )dataOut, strlen( dataOut ));
USBD_CDC_SetTxBuffer(&hUsbDeviceFS, ( uint8_t * )dataOut, strlen( dataOut ));
USBD_CDC_TransmitPacket(&hUsbDeviceFS);
HAL_Delay(1000);
}
/* USER CODE END 3 */
}The mentioned code should send "HelloWorld" every second over USB. I have connected both the USBs to STM32WB. I able to see one port which is used to for debugging/downloading but can't see the other one. Anyone with any idea?
