Using the ble_app_uart example, you should be able to see both the data you send(from the app) and receive(from nRF51 via PC/UART).

Note that the data in your UART terminal(on PC) will not be sent to the phone before you either send a newline character('\n') or the data string reach BLE_NUS_MAX_DATA_LEN characters (20).

Relevant code-lines:

  if ((data_array[index - 1] == '\n') || (index >= (BLE_NUS_MAX_DATA_LEN)))
            {
                err_code = ble_nus_string_send(&m_nus, data_array, index);
                if (err_code != NRF_ERROR_INVALID_STATE)
                {
                    APP_ERROR_CHECK(err_code);
                }

                index = 0;
            }

In e.g. Termite terminal program, you can configure the text to be transmitted with new-line character by selecting the "Append LF" option:

thank you very much, I used to use the nRF-Toolbox app, but I found that this can only watch the data we send to the computer, it is not able to watch what we recieve from the PC

Hi,

The old UART 2.0 app is deprecated (over 3 years since last update). I strongly recommend using the nRF-Toolbox app, and use the UART function there instead.
