Reducing current draw when UART is idle.

Reducing current draw when UART is idle.https://devzone.nordicsemi.com/f/nordic-q-a/12104/reducing-current-draw-when-uart-is-idleI have an application that needs to minimize its current consumption when sleeping. From the nRF52 manual, I see that UART should consume 1uA when in idle. The total current draw (CPU sleeping + UART idle) that I'm expecting should be around 2.5uA-3.0uAen-USTelligent Community 13Wed, 24 Feb 2016 11:46:58 GMTRE: Reducing current draw when UART is idle.https://devzone.nordicsemi.com/thread/45808?ContentTypeID=1Wed, 24 Feb 2016 11:46:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b3405ef4-bd1a-4b3e-a35a-5b3c6c8f6649Ole Bauck<p>The idle current is for uart peripheral only. The uart may request some other resources that is responsible for the current draw you see. You should disable the uart when you are not using it. You can do this with the hardware flow control pins or use two separate gpio pins, see <a href="https://github.com/NordicSemiconductor/nrf51-UART-examples/tree/master/ble_app_uart_low_power">this</a> example for nRF51.</p><div style="clear:both;"></div>
