https://devzone.nordicsemi.com/f/nordic-q-a/55037/disabling-nrf9160-uart-during-runtimeHello, I am currently working on incorperating the UART on the nRF9160 into my application to communicate with an nRF52. At present this is working well, with UART interrupts generating whenever I send send TX data to the nRF9160&#39;s UART1 peripheralen-USTelligent Community 13Mon, 04 Mar 2024 08:20:30 GMThttps://devzone.nordicsemi.com/thread/471953?ContentTypeID=1Mon, 04 Mar 2024 08:20:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:84af97d6-bc30-4395-9a2f-5a18f45aec7cLuckyMan<p>Hi&nbsp;<a class="internal-link view-user-profile" href="https://devzone.nordicsemi.com/members/mjd093">MJD093</a>,</p> <p>Can you please give me some of your experience?&nbsp;</p> <p>You mentioned that your application only consumes around 7uA in the IDLE mode.
