https://devzone.nordicsemi.com/f/nordic-q-a/61407/mesh-uart-coexistence-communication-with-pcHi community ! i put the same question here but with less explaination : https://devzone.nordicsemi.com/f/nordic-q-a/61393/mesh-uart-coexistence-communication-with-pc I&#39;m currently working on the coexistence code between uart and BLE Mesh.

It would use the UART peripheral on the NRF52 to output the data to the (real) UART interface, not wirelessly.&nbsp;<br />Please study the ble_app_uart example before testing with the&nbsp;<span>ble_app_uart_coexist.</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/250206?ContentTypeID=1Fri, 15 May 2020 13:43:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7e4c9845-ddf6-4bb3-8eed-5f9a89f9e3daPaulGui<p>Yes, i&#39;m using Uart service (NUS) via BLE to send data from my pc to nRF52840 with ble_app_uart_coexist.<br />Does UART (app_uart) is still a wireless way to get all info ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/250196?ContentTypeID=1Fri, 15 May 2020 13:21:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d8c76c22-aa51-4d61-9659-efeb5d1bfc89Hung Bui<p>I assume you are talking about UART service (NUS) via BLE, not the UART hardware interface ?&nbsp;<br />Are you testing using&nbsp;ble_app_uart_coexist ?&nbsp;<br />The logging module in mesh uses RTT by default. You would need to use UART directly (app_uart) to print the data you need out.&nbsp;</p><div style="clear:both;"></div>
