I recently use the uart with nRF51822，but I can not find the APP for Android，can anyone give me a link ？I have no permition to download from the official website

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.

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

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:
