https://devzone.nordicsemi.com/f/nordic-q-a/52644/uart-disable-enable-damages-uart-on-nrf9160hi all, i&#39;m using uart with easyDMA, and i&#39;m disabling and enabling it back on my code. before disabling the uart TX and RX works fine. after disable&amp;enable i get wrong data on RX. what i get on RX is always the same bytes, even after restarting the deviceen-USTelligent Community 13Fri, 27 Sep 2019 11:33:34 GMThttps://devzone.nordicsemi.com/thread/212261?ContentTypeID=1Fri, 27 Sep 2019 11:33:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b2cda71f-4d81-4133-bd5a-4da8c40bd01fH&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>When issuing STOPRX, you should wait for the RXTO event, as described here, before disabling the peripheral:</p> <p><a href="https://infocenter.nordicsemi.com/topic/ps_nrf9160/uarte.html?cp=2_0_0_5_18_6#concept_twi_low_power">https://infocenter.nordicsemi.com/topic/ps_nrf9160/uarte.html?cp=2_0_0_5_18_6#concept_twi_low_power</a></p> <p></p> <p>After this event has occurred, you can potentially have received a transaction, which can check via the ENDRX event (or FLUSHRX if you&#39;re not interested at that point). I do not know how the rest of the logic is here, but if you also have disabled interrupts prior to disabling the receiver, it is potentially a payload that has been transferred from the previous run.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
