&lt;p&gt;&lt;/p&gt;
&lt;p&gt;This blog is very helpful for someone who wants to check CMW500.&lt;/p&gt;
&lt;p&gt;Please allow me to ask for something.&lt;/p&gt;
&lt;p&gt;Is there a configuration about this on CMW500?&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-1c6dd6ab-ecea-4bde-a91b-b8ccbc33da93/CMW500.png" /&gt;&lt;/p&gt;
&lt;p&gt;One of the customers needs the value of &amp;quot;NB Index&amp;quot; for nRF9160.&lt;/p&gt;
&lt;p&gt;The equipment engineer said that this value came from the vendor.&lt;/p&gt;&lt;img src="https://test-devzone.nordicsemi.com/aggbug?PostID=1311&amp;AppID=21&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item><item><title>RE: External GPS antenna on nRF9160 DK</title><link>https://test-devzone.nordicsemi.com/guides/cellular-iot-guides/b/hardware-design/posts/external-gps-antenna-on-nrf9160-dk</link><pubDate>Wed, 01 Jul 2020 12:54:55 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:7afbbeb4-6f65-4922-8172-347039b4e7a0</guid><dc:creator>user66886</dc:creator><slash:comments>0</slash:comments><description>&lt;p&gt;Woudl the internal GPS antena wwork on this rev?

&lt;p&gt;Unfortunately the best value achieved is 508uA, with the following changes:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Disable serial in example&lt;/li&gt;
&lt;li&gt;Disable serial in spm&lt;/li&gt;
&lt;li&gt;Comment #include uart.h in example due to recent change&lt;/li&gt;
&lt;li&gt;Add the following line to top of&amp;nbsp; main: `while(1) k_sleep(1000);`&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;Disable things that could print at uart&lt;br /&gt;
&lt;div style="font-weight:normal;"&gt;
&lt;div&gt;&lt;span&gt;CONFIG_AT_HOST_LIBRARY&lt;/span&gt;&lt;span&gt;=n&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style="font-weight:normal;"&gt;
&lt;div&gt;&lt;span&gt;CONFIG_STDOUT_CONSOLE&lt;/span&gt;&lt;span&gt;=n&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;
&lt;div style="font-weight:normal;"&gt;
&lt;div&gt;&lt;span&gt;CONFIG_LOG&lt;/span&gt;&lt;span&gt;=n&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;&lt;span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;&lt;span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;&lt;span&gt;This results in 510uA power draw.&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;&lt;span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;&lt;span&gt;The interesting results is however that at some point I managed to build a minimal code example with just k_sleep as a secure image and then the power consumption was 4.8uA. Any thoughts?&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;/li&gt;

&lt;p&gt;&lt;span&gt;1. Do you know why it takes around 1 minute to finish sending? When I use the default amount of data (sizeof(ntp_format)), it takes around 12 seconds from sending to go to sleep mode.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;2.
