 Simple question: 
 When I set off A DMA transmission on the UART, how do I poll for that transmission having finished? There seem to be no status bits in this UART. Is that really right or am I just being blind? I&amp;#39;ve tried looking at the EVENTS_TXDRDY</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Tue, 11 Jun 2019 12:25:26 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/48393/how-do-i-know-when-a-uarte-dma-transmission-is-finished" /><item><title>RE: How do I know when a UARTE DMA transmission is finished?</title><link>https://devzone.nordicsemi.com/thread/192066?ContentTypeID=1</link><pubDate>Tue, 11 Jun 2019 12:25:26 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:8f9824ee-5f79-4d50-ad58-94ae276d1f98</guid><dc:creator>Kenneth</dc:creator><description>&lt;p&gt;According to:&lt;/p&gt;
&lt;p&gt;&lt;a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/uarte.html?cp=3_1_0_34_2#concept_a54_2gm_wr"&gt;https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/uarte.html?cp=3_1_0_34_2#concept_a54_2gm_wr&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;The code should be close to:&lt;/p&gt;
&lt;p&gt;&lt;span&gt;NRF_UARTE0-&amp;gt;EVENTS_ENDTX = 0;&lt;/span&gt;&lt;br /&gt;NRF_UARTE0-&amp;gt;TASKS_STARTTX = 1;&lt;br /&gt;while(NRF_UARTE0-&amp;gt;EVENTS_ENDTX == 0);&lt;/p&gt;
&lt;p&gt;But maybe you can take a look at this also:&lt;/p&gt;
