https://devzone.nordicsemi.com/f/nordic-q-a/35042/current-consumption-in-nrf52Hello everybody, I use NRF52832, sdk14.2, s132 softdevice. When I install SDK examples(for example nRF5_SDK_14.2.0_17b948a\examples\ble_central\ble_app_uart_c), the minimum current consumption is 2.1mA. Previously, the samples in SDK8,10,12 had muchen-USTelligent Community 13Tue, 05 Jun 2018 09:28:55 GMThttps://devzone.nordicsemi.com/thread/134690?ContentTypeID=1Tue, 05 Jun 2018 09:28:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:470452b8-0201-480c-a4eb-109ea92762e7Stian R&#248;ed Hafskjold<p>You should be careful turning off the UART if the logging module is using it. But yes, app_uart_close() should close the UART. It&#39;s better to turn off logging in sdk_config.h.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/134555?ContentTypeID=1Mon, 04 Jun 2018 12:22:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4d1afa45-8baf-4794-972e-5e3bea559364purgoufr<p>Yes logging enabled. I think the uart consumes high power because it is open.&nbsp;How do I turn on/off the UART when I do not use it? &quot;<strong>uart_init();</strong> -&gt; to turn on /<strong> app_uart_close ();</strong> -&gt; to turn off&quot; is it enough?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/134520?ContentTypeID=1Mon, 04 Jun 2018 11:05:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aef43cf8-3b09-404e-a8f3-94b29d45e3a0Stian R&#248;ed Hafskjold<p>Can you check if logging is enabled? Go to sdk_config.h and set NRF_LOG_ENABLE to 0</p><div style="clear:both;"></div>
