nRF52 DK and UART Example on PC

[Mark]

I opened, compiled, and uploaded the UART example on my nRF52-DK board using KEIL IDE. I use either CoolTerm or RealTerm on my PC. When I open the Terminal program I can see COM port 8 connected to my nRF52-DK. I followed this setup and got connected:

Baud rate: 115.200

8 data bits

1 stop bit

No parity

HW flow control: RTS/CTS

However I don't see "Start:" nor 'Exit!' when I enter q/Q.

Aren't I supposed to connect to the Terminal program through the same USB port as for programming nRF52-DK board? Or am I supposed to use another port with an external device to get connected to Terminal program?

Thanks in advance

I can see part of the code is:

 #ifndef ENABLE_LOOPBACK_TEST
    printf("\n\rStart: \n\r");

    while (true)
    {
        uint8_t cr;
        while(app_uart_get(&cr) != NRF_SUCCESS);
        while(app_uart_put(cr) != NRF_SUCCESS);

        if (cr == 'q' || cr == 'Q')
        {
            printf(" \n\rExit!\n\r");

            while (true)
            {
                // Do nothing.
            }
        }
    }
#else

    // This part of the example is just for testing the loopback .
    while (true)
    {
        uart_loopback_test();
    }
#endif

I'm not using bluetooth, but do I need a softdevice on the chip as well?

I started debugging, and the code is running. I used LEDs to see how far I get, and it seems the code runs as it should, but I don't see the printing messages on the terminal!

Any Idea?
