https://devzone.nordicsemi.com/f/nordic-q-a/65152/uarte-transmitted-bytes-are-padded-with-extra-bits-even-with-parity-offI am attempting to send 13 bytes over UARTE1 on the nRF52840. I&#39;m using the ASYNC API in Zephyr. When I look at the output on an oscilloscope, some of the bytes show up in the sent pattern. However, there are 2+ extra bytes that are sent along with theen-USTelligent Community 13Tue, 25 Aug 2020 15:01:57 GMThttps://devzone.nordicsemi.com/thread/266296?ContentTypeID=1Tue, 25 Aug 2020 15:01:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5173c795-a026-4e7f-b9cc-213da2a76316Darby Hewitt<p>I figured it out; I realized when I was looking for my bytes on the scope, I was looking for them backwards. This was not a software problem. It was a user error. <span class="emoticon" data-url="https://devzone.nordicsemi.com/cfs-file/__key/system/emoji/1f612.svg" title="Unamused">&#x1f612;</span> Sorry!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/266285?ContentTypeID=1Tue, 25 Aug 2020 14:34:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1bd64aa4-fa1e-4bd7-a484-e65116a4d262Darby Hewitt<p>Thanks, Sigurd.</p> <p>I&#39;m using NCS 1.3.0.</p> <p>Here&#39;s my prj.conf</p> <p><pre class="ui-code" data-mode="text">CONFIG_BT=y CONFIG_BT_CENTRAL=y CONFIG_UART_NRFX=y CONFIG_SERIAL=y CONFIG_UART_ASYNC_API=y CONFIG_UART_1_ASYNC=y</pre></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/266190?ContentTypeID=1Tue, 25 Aug 2020 10:49:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7aaec9fb-54c5-4354-a999-abbd52020265Sigurd<p>Hi,</p> <p>I will try to reproduce this.</p> <p>What version of NCS(nRF Connect SDK) are you using ? v1.3.0 ?</p> <p>How does your prj.conf file look like ?</p><div style="clear:both;"></div>
