Is it possible to have a second UART on nrF52?https://devzone.nordicsemi.com/f/nordic-q-a/20455/is-it-possible-to-have-a-second-uart-on-nrf52Hello, I would be interested on knowing whether I may have a secondary UART on the nrF52 chip or not. I would like to communicate my nRF52 with a RN2483 and this is done through UART, however I see that UART is used as well (on SDK12.2) in order toen-USTelligent Community 13Tue, 14 Mar 2017 15:47:03 GMTRE: Is it possible to have a second UART on nrF52?https://devzone.nordicsemi.com/thread/79751?ContentTypeID=1Tue, 14 Mar 2017 15:47:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:43e1bc39-95a7-4f52-a016-4b62349fcc8dWojtek<p>No, enabling and selecting RTT as the logging sink. There are not many options, why don&#39;t you just open it ex. by keil configuration wizard, and just try? I don&#39;t have access to my sources at the moment, but I am sure you will get how to do it in just few minutes.

So when you enable debugging in the sdk_config.h, all that data goes to the RTT debugging or to the UART?</p><div style="clear:both;"></div>RE: Is it possible to have a second UART on nrF52?https://devzone.nordicsemi.com/thread/79747?ContentTypeID=1Tue, 14 Mar 2017 12:42:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f671d6d2-f2b1-4d8e-80cc-14718866383eWojtek<p>What I did not to waste UART for debug purpose is I moved to RTT debugging - it only utilizes SWD lines for that. There is only one uart on nRF52832. There are 2 UARTs on nRF52840 as far as I know.</p><div style="clear:both;"></div>
