I disabled UART0 after enabling and the UART0 registers are all getting its default value after disabling. But the current stays at 0.6mA, I even disabled the UART PINs to input floating but stillen-USTelligent Community 13 Non-ProductionFri, 27 May 2022 18:31:56 GMThttps://test-devzone.nordicsemi.com/thread/369829?ContentTypeID=1Fri, 27 May 2022 18:31:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:14f2eaad-b37c-41a4-9ad5-6ee2d2cfed8buser35341<p>Hi, sorry I forgot to comment here. It is solved today, Earlier I was trying to disable uart inside ble data receive handler and now I am setting a flag from there and disabling it in main while loop above the power management loop and there after it is entering into low power mode and current is becoming almost near to 2 uA which is perfect for my application.</p><div style="clear:both;"></div>https://test-devzone.nordicsemi.com/thread/369812?ContentTypeID=1Fri, 27 May 2022 14:50:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3ca46ddd-c4d2-48cd-b991-22c01ad01869user14926<p>Hi,</p> <p>Can you check if the workaround in <a href="https://test-devzone.nordicsemi.com/f/nordic-q-a/61499/un-init-and-then-re-init-buarte_async-module-will-report-nrf_libuarte_async_evt_error/250330#250330">this post</a> works?</p> <p>Are you un-initing the UART when there is a receive operation in progress?</p> <p>Do you enable the HFCLK in explicitly in your application?</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>https://test-devzone.nordicsemi.com/thread/369719?ContentTypeID=1Fri, 27 May 2022 07:20:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0abc3099-e6c2-48ac-bfec-b4f8f29844b3user35341<p>Any clue ?</p><div style="clear:both;"></div>
