 I had the board run the following code to connect it to the cellular tower: 
 #include &amp;lt;zephyr.h&amp;gt; #include &amp;lt;stdio.h&amp;gt; #include &amp;lt;string.h&amp;gt; #include &amp;lt;lte_lc.h&amp;gt;

Do you experience the board resetting when running&amp;nbsp;the asset_trackker?&lt;/p&gt;
&lt;p&gt;Since you&amp;#39;re having issues with connecting I will need to have AT_client output. This has more debugging information for us to look through.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;What do you receive from:&lt;br /&gt;&lt;pre class="ui-code" data-mode="text"&gt;int ret = lte_lc_init_and_connect();&lt;/pre&gt;&lt;/p&gt;
&lt;p&gt;Please&amp;nbsp;provide some debug information from your code.&lt;/p&gt;
&lt;p&gt;Thanks&lt;br /&gt;&lt;br /&gt;Kind regards,&lt;br /&gt;Oeyvind&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrf9160 board unexpectedly reboot itself after cellular connection is established</title><link>https://devzone.nordicsemi.com/thread/177214?ContentTypeID=1</link><pubDate>Wed, 20 Mar 2019 06:41:07 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:00e9b339-fb92-4016-898c-876afe32401b</guid><dc:creator>Kai</dc:creator><description>&lt;p&gt;Hi Oyvind,&lt;/p&gt;
&lt;p&gt;The code is based on asset_tracker, simply replacing main.c with the above code.&lt;/p&gt;
&lt;p&gt;&lt;span style="text-decoration:underline;"&gt;&lt;em&gt;Is the board resetting or do you mean the connection?&lt;/em&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;I meant &amp;quot;the board is resetting&amp;quot;.&lt;/p&gt;
&lt;p&gt;If I run the original Nordic asset_tracker code, I could see several resets happen before the connection is established successfully. Please see the attached log.&lt;a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/log_5F00_LTE_5F00_LC_5F00_reboot.txt"&gt;devzone.nordicsemi.com/.../log_5F00_LTE_5F00_LC_5F00_reboot.txt&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;Best,&lt;/p&gt;
&lt;p&gt;Kai&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrf9160 board unexpectedly reboot itself after cellular connection is established</title><link>https://devzone.nordicsemi.com/thread/177009?ContentTypeID=1</link><pubDate>Tue, 19 Mar 2019 12:50:37 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:1fd01622-74a4-4b18-a0a1-8ce545b1823e</guid><dc:creator>&amp;#216;yvind</dc:creator><description>&lt;p&gt;Hello Kai,&lt;br /&gt;&lt;br /&gt;Can you please provide some background information?

&lt;p&gt;&amp;nbsp;Is the board resetting or do you mean the connection? If its the connection, can you please provide the output from the at_client application? This gives some debugging information we can work with.&lt;br /&gt;&lt;br /&gt;Kind regards,&lt;br /&gt;Oeyvind&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
