 I’m trying to finish the first exercise of lesson 1, but when I save it to flash and run the binary, I get this error and I don’t know what’s causing it. 
 
 Could someone help me? I’ve simply exported the example mentioned in the instructions:</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Sun, 14 Dec 2025 19:39:12 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/125908/problem-with-wi-fi-fundamental-lesson-1---exercise-1" /><item><title>RE: Problem with Wi-Fi Fundamental: Lesson 1 - Exercise 1</title><link>https://devzone.nordicsemi.com/thread/556935?ContentTypeID=1</link><pubDate>Sun, 14 Dec 2025 19:39:12 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:127266de-904b-473e-a4b5-a4fcfd9c86e4</guid><dc:creator>oscargomezf</dc:creator><description>&lt;p&gt;Hi Mikel,&lt;/p&gt;

&lt;p&gt;Have you tried restarting your phone, and/or turning bluetooth on/off to see if this has any impact?&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Great to hear that you got some progression on this issue.&lt;/p&gt;
&lt;p&gt;There should be a pop-up with a pairing notification from the android system after connecting, like this:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1764839829227v2.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;Before you can fill in your SSID/password, and crypto option.&lt;/p&gt;
&lt;p&gt;Could you check if there is any permissions on that app that is denied?&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Please note that if using WPA/WPA2 mixed mode selection, then there is a known issue on NCS v3.1.x at this time, and you will need to cherry pick this fix:&lt;/p&gt;

&lt;p&gt;Could you check if your flashed the merged image, or the sub-image? Make sure that the &amp;quot;build&amp;quot; catalog is selected in blue here, and not &amp;quot;ble&amp;quot; or &amp;quot;ipc_radio&amp;quot; before pressing &amp;quot;flash&amp;quot;:&lt;/p&gt;
