https://devzone.nordicsemi.com/f/nordic-q-a/92758/nrf-sdk-disabling-nrf-async-uart-at-run-timeHi, The nRF UART running over the ASYNC interface consumes a lot of current even when not in use. As ours is a battery-operated device we intended to disable UART when not in use. And enable dynamically as required. Please suggest a way to get thisen-USTelligent Community 13Tue, 11 Oct 2022 11:29:41 GMThttps://devzone.nordicsemi.com/thread/390241?ContentTypeID=1Tue, 11 Oct 2022 11:29:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:656fe080-da98-4828-a484-6a2095b278c5J&#248;rgen Holmefjord<p>Hi,</p> <p>You can use the APIs <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.1.0/zephyr/hardware/peripherals/uart.html#c.uart_rx_disable">uart_rx_disable</a><span>() and <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.1.0/zephyr/hardware/peripherals/uart.html#c.uart_rx_enable">uart_rx_enable</a>() to dynamically stop and start the async UART during runtime. The TX should generally not be an issue, as it will stop once the transfer is done, but there is also a&nbsp;<a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.1.0/zephyr/hardware/peripherals/uart.html#c.uart_tx_abort">uart_tx_abort</a>() API that can be used for stopping transfers.</span></p> <p><span>Best regards,<br />Jørgen</span></p><div style="clear:both;"></div>
