https://devzone.nordicsemi.com/f/nordic-q-a/53678/uarte-dma-keeps-clock-activeHi, for a new project we use the NRF52480, I can get it into low power mode with a total use of 20&#181;A ( with all the other hardware on the board ). But when I initialize the UARTE, even without communicating, the current consumption jumps to 610&#181;A whenen-USTelligent Community 13Mon, 28 Oct 2019 13:20:46 GMThttps://devzone.nordicsemi.com/thread/217091?ContentTypeID=1Mon, 28 Oct 2019 13:20:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:28cadef1-9332-4ae0-b09e-e4c75b44ff9eSigurd<p>Hi,</p> [quote userid="84531" url="~/f/nordic-q-a/53678/uarte-dma-keeps-clock-active"]I have already tried disabling the UARTE peripheral even after waiting for the last writing action of the DMA but nothing seems to work.[/quote] <p>Did you use&nbsp;<span>nrfx_uarte_uninit() /&nbsp;nrf_drv_uart_uninit() for this ?</span></p> <p><span>If yes, make sure that use the latest version of nrfx.&nbsp;The&nbsp;new driver version now waits for&nbsp;TX_STOPPED event before disabling the&nbsp;peripheral. This&nbsp;gracefully uinit of the UARTE peripheral was introduced in nrfx v1.7.2. See&nbsp;<a href="https://github.com/NordicSemiconductor/nrfx/blob/master/drivers/src/nrfx_uarte.c#L266">this link.</a>&nbsp;(Note that SDK 15.3 is bundled with nrfx v1.6.2)</span></p><div style="clear:both;"></div>
