We have our unit in eDRX mode, using flow control on UART0, and only get WakeUp interrupts when we receive a SMS message, which is exactly what we want.

&lt;p&gt;Not necessary to send ACK twice, so no.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to ACK received SMS messages using SLM</title><link>https://devzone.nordicsemi.com/thread/403652?ContentTypeID=1</link><pubDate>Fri, 06 Jan 2023 18:53:36 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:4824a1b0-4903-4021-9714-2e41d4955fc8</guid><dc:creator>Bryan Mills</dc:creator><description>&lt;p&gt;That didn&amp;#39;t actually answer my question. Do I need to send an ACK, yes or no?&lt;/p&gt;
&lt;p&gt;If no, then I assume the answer is no because &amp;quot;it is already handled in the the lib_sms library&amp;quot;.&lt;/p&gt;
&lt;p&gt;If the answer is yes, then I assume I need to use something in the &lt;span&gt;lib_sms&amp;nbsp;&lt;/span&gt;library to send the ACK and I will need to know what that is.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to ACK received SMS messages using SLM</title><link>https://devzone.nordicsemi.com/thread/403569?ContentTypeID=1</link><pubDate>Fri, 06 Jan 2023 12:31:32 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:00449deb-665c-4faf-9a86-e945e3aa9a76</guid><dc:creator>Hakon</dc:creator><description>&lt;p&gt;Hello,&lt;/p&gt;
[quote user=""]My question is, do I need to send an ACK and if so, how do I do that so I don&amp;#39;t get an error?[/quote]
&lt;p&gt;it is already handled in the &lt;a href="https://github.com/nrfconnect/sdk-nrf/blob/main/lib/sms/sms.c#L83"&gt;lib_sms library&lt;/a&gt;.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
