 I made one-shot agps app by modifying gps sample app. The behavior is this. 
 - download SUPL data from supl.google.com before first fixing &amp;lt; loop &amp;gt; - enable LNA - turn on GPS(AT+CFUN=31) </description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 08 Oct 2020 08:30:34 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/63536/why-does-agps-take-a-long-time-like-5-to-20-sec-to-fix" /><item><title>RE: Why does AGPS take a long time like 5 to 20 sec to fix?</title><link>https://devzone.nordicsemi.com/thread/273658?ContentTypeID=1</link><pubDate>Thu, 08 Oct 2020 08:30:34 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:53671f86-8ab0-442d-9628-4a31ecdf5eab</guid><dc:creator>mikael.kallberg</dc:creator><description>&lt;p&gt;Hi Yusuke.&lt;/p&gt;
&lt;p&gt;Do you still have the code for the mentioned ?&lt;br /&gt;I would be really happy if you do and would share it?&lt;br /&gt;Thanks // Mike&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Why does AGPS take a long time like 5 to 20 sec to fix?</title><link>https://devzone.nordicsemi.com/thread/261858?ContentTypeID=1</link><pubDate>Tue, 28 Jul 2020 00:09:28 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:2c514c4d-dd8e-4f60-bb79-255bcdf34d53</guid><dc:creator>Yusuke</dc:creator><description>&lt;p&gt;I figured out the cause of this issue. I initiated and started and close socket after I get the first fix every time. This causes the slow GPS fix. I initiate GPS socket only once and start/stop GPS repeatedly. Then hot start works out.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Why does AGPS take a long time like 5 to 20 sec to fix?</title><link>https://devzone.nordicsemi.com/thread/259185?ContentTypeID=1</link><pubDate>Thu, 09 Jul 2020 12:49:15 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:4db05ce2-5f58-43b3-bf8f-706d980096ba</guid><dc:creator>Yusuke</dc:creator><description>&lt;p&gt;That&amp;#39;s fine.
