Hello, I am using Telink B91 development kit for my application, when i connect the Development board to PC trough burning EVK i am able to dump the code and also i tested the code with BLE it is working fine, But when it comes to UART the COM port is not showing, What i need to do? Weather i need to install any driver or anything wrong with the code.(I am testing it by the UART DEMO code).

In short, you can use uart_send_byte to send data to the USB to Serial tool so that your computer can receive the data
For more information on the use of the API, please refer to the UART_Demo example.

Here the COM port is not showing in the Device manager, when i connect my device with EVK to PC it is showing some Printing device.

You need a USB to Serial tool
