https://devzone.nordicsemi.com/f/nordic-q-a/35307/uart-rx-tx-signals-routingHi I would like to connect the nRF52810 to 2 devices via UART interface by switching the Rx and TX GPIO pins by the software in realtime. Is it possible? what is the method to do that?

A simple example of using the UARTE peripheral through the registers can be found on <a href="https://github.com/andenore/NordicSnippets/blob/master/examples/uart/main.c">this page</a>.

Uninitializing the old UART interface and initializing it with new pins should be sufficient. How to do this depends on how you setup the UART interface (<a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52810.ps/uarte.html?cp=2_2_0_5_24_8#topic">Registers</a>, <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/group__nrf__uarte__hal.html?cp=4_0_0_6_9_0_29_1">HAL</a>, <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/group__nrfx__uarte.html?cp=4_0_0_6_9_0_29_0">driver</a>, <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/group__app__uart.html?cp=4_0_0_6_11_57">app_uart</a> library, <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/lib_serial.html?cp=4_0_0_3_39">nrf_serial</a> library, <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/group__nrf__libuarte.html?cp=4_0_0_6_11_15">libuarte</a> library, etc.)</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
