https://devzone.nordicsemi.com/f/nordic-q-a/78017/ble-uart-dataDear Members, I used E:\nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ble_app_uart\main.c I can see it&#39;s running in COM11 from J-link, but I can not see any datas transmitted via bluetooth ? How can I see data transmitted on bluetoothen-USTelligent Community 13Fri, 30 Jul 2021 06:43:51 GMThttps://devzone.nordicsemi.com/thread/322582?ContentTypeID=1Fri, 30 Jul 2021 06:43:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d2edbfaa-31c4-47b0-bfc1-897f9fddfe81Amanda Hsieh<p>Hi Rixtronix,</p> <p>I would suggest you use&nbsp;<a href="https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-mobile">nRF-Connect-for-mobile</a>&nbsp;if you don&#39;t have extra DK to run the BLE app.&nbsp;</p> <p>Connect the board to the computer using a USB cable. The board is assigned a COM port, which is visible in the Device Manager. I think you already did this in your first figure.&nbsp;</p> <p>Refer to the instructions in the <a title="Testing" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/ble_sdk_app_nus_eval.html?cp=8_1_4_2_2_25_2#project_uart_nus_eval_test">Testing</a>. S<span>elect the UART RX characteristic value in nRF Connect to send the value and check the COM listener and vice versa (check UART TX characteristic value in nRF Connect).&nbsp;</span></p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/274081_5F00_1.PNG" /></p> <p>-Amanda H.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/322554?ContentTypeID=1Fri, 30 Jul 2021 01:04:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b8195d6d-1695-4ea6-9153-98bdde29769cRixtronixLAB<p>Hi Amanda,</p> <p>I can pair and connect to Nordic_UART</p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/2021_2D00_07_2D00_30-09_5F00_02_5F00_11_2D00_Bluetooth-Explorer.png" /></p> <p>but I can not send and receive a text on any COM ?</p> <p>How can I send and receive with COM in my PC, any codes need update ?</p> <p></p> <p>Regards</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/322449?ContentTypeID=1Thu, 29 Jul 2021 12:17:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d8aaa589-959f-4b48-a76f-33fbb0a1b7a7Amanda Hsieh<p>Hi,&nbsp;</p> <p>You can test the UART Application with the <a href="https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-mobile">nRF-Connect-for-mobile</a>&nbsp;or <span>nRF Connect&nbsp;</span><a href="https://www.nordicsemi.com/Products/Development-tools/nrf-connect-for-desktop">for-desktop</a>/&nbsp;<strong><a href="https://infocenter.nordicsemi.com/topic/ug_nrfconnect_ble/UG/common/nrf_connect_app_installing.html">Bluetooth Low Energy app</a>.&nbsp;</strong></p> <p>-Amanda H.&nbsp;</p><div style="clear:both;"></div>
